Message from the refi nery management
The Data Book of Health, Safety and the Environment of
Matosinhos refi nery, which is annually published, is an
opportunity for evaluation. Thus, as in previous years, here
we disclose in our 2011 Data Book, the results of the key
performance indicators for Health, Safety and the Environment
of our refi nery. In this document we focus on the assessment
of the goals achieved and the new challenges, and above all,
on what, with humility, we recognize the power and duty to
make even better.
If 2010 was the year of construction, 2011 will remain for
the refi nery records as the starting year of the new vacuum
distillation and visbreaking units offi cially inaugurated on
September 28th by His Excellency the President of the
Republic, Dr. Aníbal Cavaco Silva. The commissioning and
start up of the new units, a complex and time-consuming
activity, was performed in a professional and competent
way by an enthusiastic team. We are proud to announce
the non-occurrence of any accidents related to this activity.
Nevertheless, we cannot fail to register an internal outbreak
in a reservoir and hence take its lessons, in spite of all the
prevention mechanism and response to occurrence having
worked properly.
Also the environmental plan was featured in 2011. An
ambitious program of monitoring the ambient air quality
was carried out in a surrounding area of approximately
35 km 2 around the refi nery, measuring the main volatile
organic compounds, including benzene. It was possible to fi nd
that in all inhabited areas, whether in the north, the south or
at the east of the refi nery, the concentrations of pollutants are
lower in all monitored points than the required rigorous legal
limits.
In addition to the concern over air, the refi nery discharges
to the marine environment water used in its activities after
having been fully treated and purifi ed. In 2011 we have reused
43% of such water. Also in 2011 and for the fi rst time, all the
beaches from the seafront of Leça da Palmeira and Perafi ta
were awarded the blue fl ag. This evidences the healthy
coexistence between the refi nery and other industrial units and
the Environment.
We wanted to share our enthusiasm with the Environmental
improvement and have proceeded with the architectural
redevelopment of the access area through Rua Belchior Robles
and have planted trees along Rua Coronel Helder Ribeiro, in the
west front of the refi nery.
Key indicators of Safety, particularly the Accident Frequency
Rate with lost workday injuries, that are kept below the
average of the european refi ning sector operators, and far
below the national indicators, give us the strength to continue
on the path of continuous improvement, always investing in
the training of our workers and the qualifi cation of our suppliers
and partners, putting the refi nery at the forefront of safe
workplaces.
Director of the refi nery of Matosinhos
We are a modern refi nery that wants to be asserted by a
positive relationship with the community in which it operates,
with respect for fundamental values of protecting the health
and safety of the human person and the establishment of a
sustainable relationship with the environment.
Our values are increasingly present and we keep repeating
them:
• all our activities and decisions are supported by a strong
safety culture;
• our commitment towards the environment goes beyond legal
issues. We aim a sustained integration in the surroundings.
It is in defense of these values that in 2012 we intend to obtain
integrated certifi cation in Energy, Safety, Environment and
Quality. We trust that energy effi ciency cannot be dissociated
from the environment protection including by reducing
greenhouse gases emission.
To be in the fi rst quartile of the best European refi ning
operators in 2015 in terms of energy intensity, it is a
challenging goal and we are getting closer, as the plan for
energy effi ciency improvements will be achieved either
with investments for energy recovery, or by the use of more
environment friendly fuels. We will thus build a legacy, based
upon a strong culture of Health, Safety and the Environment,
that we can all be proud of in generations to come.

Introduction
INTRODUCTION 03 04 05 06 07 08 09 10 11
This is the fi fth edition of the Data Book on Health, Safety and
Environment of Matosinhos refi nery.
We have been presenting the performance of Matosinhos
refi nery in its most relevant indicators for Health, Safety and
the Environment with full transparency and rigor. The results
presented herein are, once again, the translation of the
effort of all those who earnestly and devotedly collaborate
in this industrial unit to ensure a sustained performance of
excellence by which we are already recognized.
This way, we have been attentive to the suggestions of our
readers, and thus we seek to refl ect them in the editorial,
graphics and content development that the Data Book has
been experiencing. This year, as opposed to the 2010 Data
Book, where a strong focus was made on investments when
describing the refi nery expansion, we have embarked on a
more synthetic, more direct and lighter approach. Obviously,
we have kept the core of the Data Book, focusing on the
presentation of performance indicators for Health, Safety
and Environment without major changes once an evolution
of continuity is warranted. The sections aimed at publicizing
the operational aspects of our refi nery were synthesized
without failing to focus on projects and facilities which
were structuring for the construction of a safer and more
environmentally responsible refi nery and which deserve a
prominent place in these pages.
The numerical information presented in the Data Book has
been showing the evolution since its origin from the year
2005. In 2010 it was still possible to include the fi rst year of
reporting, but from now on and in the name of a lively, more
appealing graphic design, we will only present the data for
the last fi ve years. So this year, the series presented cover
the period from 2007 to 2011. Readers, whom we failed to
deliver the Data Books from previous years and who might
be interested in information for the years 2005 and 2006,
we have the greatest pleasure to make them receive the
previous issues.
We have already mentioned the attention we give to
suggestions from our readers. This Data Book is for them
and it only makes sense if it meets their expectations as a
source of information, whether for their work, whether for the
interests it holds in relation to the refi nery or even as a mere
pleasure to become aware of something different. Everyone
is asked, earnestly, whether it is understood that we can do
differently, whether we can do better, to please complete
the questionnaire attached to the Data Book and refer it to
the address refi nariadematosinhos@galpenergia.com and
AmbAQSCorp@galpenergia.com.
Given the responsiveness that the english edition of the
Data Book has been evidencing, this year we will continue
to ensure it, as in the previous two years. We will, therefore,
be opening our doors to a wider range of readers, at a time
when our company is open to the world, with an investment
of unprecedented internationalization.
The Data Book is intended as a practical and easy document
conveying information that is reliable, trustworthy and
accurately presented. It is addressed to our customers and
suppliers, our employees, our shareholders and investors
in general, public authorities, the academic world and the
media. It is for all stakeholders in respect of the Matosinhos
refi nery and the urban environment in which it operates. The
data appropriately framed and defi ned in the Glossary section,
are reproducible and trustworthy. Actually they were subject
to verifi cation by an external auditor in order to demonstrate
the veracity and accuracy of the information herein made
available. Everybody is invited to use these data as a means
to satisfy your interest, your curiosity or even as a help in
your work. We will be happy to assist in these tasks. We wish
you a good reading.

The HSE Committee (HSEC) of Matosinhos refi nery is
constituted by the board members, heads of the Health, Safety,
Environment and Quality (HSEQ) areas and by the occupational
physician. the HSEC is also constituted by the responsible
members for the Lubricants Plant and the Boa Nova Depot,
to ensure a proper coordination of actions and information
exchange with these units.
Directly under the HSEC of the refi nery there are the HSE
Sub-Committees (SubHSEC) for each Factory and for Storage
and oil movements, which ensure the disclosure and alignment
with the HSEC. These SubHSEC are usually composed by the
responsible for the area, the deputy chief, shift supervisor, two
operators (at least one from outdoors), the representative of
the zone maintenance, the representative of zone inspection,
the hse element for zone support, and other elements that
may participate temporarily or permanently.
In 2011 the Groups for Excellence (GE) of the refi nery were
active and were dedicated to the report and investigation of
events and incidents and the policies and procedures group.
In addition to the structure here above represented, Matosinhos
refi nery also participates in corporate GE, particularly in the GE
Process Safety, for which it is the leader, and the GE Service
Providers.
Location and surroundings
Matosinhos refi nery is located on the Douro Coast between
Boa-Nova and Cabo do Mundo, in the parishes of Leça da
Palmeira and Perafi ta, in the municipality of Matosinhos. It
covers an area of approximately 400 ha, to the northeast of the
city of Porto, about 2 km north of the Terminal de Leixões.
The refi nery has good access roads and a link to the Oil
Terminal and monobuoy, by which raw materials are received
and fi nished products dispatched.
The following facilities in the refi nery surroundings deserve
special mention:
• Perafi ta Gas Depot (Parque de Gas Perafi ta), with facilities
for Liquid Petroleum Gas (LPG) storage and fi lling of tanker
vehicles and cylinders, situated to the northeast of the
refi nery;
• Boa Nova Private Hospital;
• canning factory, vehicle repair workshops and garages, about
150 m from the refi nery fence;
• urban spaces and population centres, namely Leça da
Palmeira and Matosinhos to the south, Aldeia Nova, Poupas
and Telheira to the north, and Almeiriga, Amorosa, Goncalves
and Avessada to the east;
• forest, agricultural land and bush land;
• dunes with typical vegetation.
FRAMEWORK 04 05 06 07 08 09 10 11
There are no Nature conservation areas close to the refi nery.
The following is a list of the land-planning schemes in force for
the region bordering the refi nery:
• Leça River Catchment Scheme (Plano de Bacia Hidrográfi ca do
Rio Leça);
• Caminha – Espinho Coastal Strip Land-use Plan (Plano de
Ordenamento da Orla Costeira Caminha – Espinho);
• the Forest Land-use Plan for the Porto Metropolitan Area and
between Douro and Vouga (Plano Regional de Ordenamento
Florestal da Area Metropolitana do Porto e Entre Douro e Vouga);
• northern Region Land-use Plan (Plano Regional de
Ordenamento do Territorio para a Regiao Norte);
• management scheme for the Municipality of Matosinhos
(Plano Director Municipal de Matosinhos);
• urbanisation scheme between Rua de Belchior Robles and
Avenida dos Combatentes da Grande Guerra in Leça da
Palmeira (Plano de Urbanizacao entre a Rua de Belchior
Robles e a Avenida dos Combatentes da Grande Guerra em
Leça da Palmeira).
Although multiple operators contribute to the air and water
quality in the region under the infl uence of the Matosinhos
industrial complex, and given that the refi nery monitors
liquid and gas emissions to control the impact of its activity,
it is relevant to provide information on the quality of these
descriptors in the surroundings.
The municipality of Matosinhos is part of a monitoring network
of the air quality in the Northern Region and is included in
the agglomeration of the Porto Coast. Of the 15 stations that
compose the agglomeration of Porto Coast and that are spread
between Espinho, Gondomar, Maia, Matosinhos, Porto, Vila do
Conde and Valongo, fi ve are located in Matosinhos.
The following graphs show the history of the Air Quality Index
for the Porto Coast region. It can be seen that the quality of air
has improved consistently.

In terms of surface water, the region is the watershed between
the Leça River and Onda River catchments. Watercourses are
temporary, with natural drainage occurring only after signifi cant
rainfall.
Groundwater resources have low vulnerability to pollution.
The beaches in front of the Matosinhos refi nery constitute a
large part of its surroundings, and all of them were rewarded in
2011 with the blue fl ag.

Historical Overview
MATOSINHOS REFINERY / DATA BOOK ON HEALTH, SAFETY AND ENVIRONMENT 2011
The blue fl ag symbolizes environmental quality and
consequently respect for the criteria of environmental
information and education, for the quality of water, for
environmental management and also for the safety and
services provided.
The blue fl ag award is therefore an indicator of environmental
quality for which the excellent performance of the refi nery has
contributed strongly, not only in the fi eld of water but also on
the part of air quality.
Matosinhos refi nery integrates this context and proves that its
“commitment to the environment goes beyond legal issues,
always looking for a sustainable integration in the environment”.

million tonnes of crude oil per year, producing a wide range of
refi ned commercial products, namely:
• Liquid petroleum gas
• Petrol
• Naphtha
• Jet/Kerosene
• Diesels
• Fuels
• Base oils
• Lubricating oils
• Paraffi ns
• Aliphatic and aromatic, solvents, benzene,
toluene and xylenes
• Bitumen
The storage capacity of the refi nery is currently 767,132 m 3
crude oil, amounting to a total of 1,865,096 m 3 of storage
capacity.
The management and production plans of the refi nery, with
an impact in the storage management, consider the need to
ensure the safety of supply of the petroleum products market.
Description of the principal raw materials
Matosinhos refi nery refi nes two types of crude: SOUR and
SWEET, the names deriving from their sulphur content. The
crude oil in 2011 came mostly from Saudi Arabia, Brazil, Algeria,
Nigeria, Angola, Cameroon and North Sea.
In July 2011, the refi nery adjusted its crude oils mix as the new
Vacuum and Visbreaker units started to operate, being able to
load heavier and more acid crudes and diversifying the sources.
From January to May, the crude oils came mostly from Algeria,
Nigeria and North Sea, with an API of 40.5º and average acidity
of 0.1% (m/m).
From June to December, with the startup of the new units, the
mix has been adjusted to heavier crude oils, with an average
API of 30.7º and higher acidity, about 0.4 % (m/m), mainly
coming from Brazil and Angola.

4.1 Cogeneration construction
The new Cogeneration Plant – Matosinhos
refi nery PORTCOGERAÇÃO
Within a short time, Matosinhos refi nery will enjoy, together
with Sines refi nery, the largest and most modern Cogeneration
power center existing in the country. It will be the aftermath
of a project long desired by the refi nery and that will make
a decisive contribution in the energy optimization of Galp
Energia’s Industrial Complex as well as on reducing its
environmental impact.
Since the beginning this project has overlapped the conclusion
of the Cogeneration Center of Sines (SINECOGERAÇÃO), which
has the same kind of design, so it was possible to transpose
into this second the experience of the fi rst.
Indeed, and taking advantage of the sequence relationship
in constructing both plants, Galp Power used the same team
of engineers for the management and supervision of both
projects with all the benefi ts it carries along.
On the other hand, both Galp Energia Refi neries will use the
same kind of technology in the simultaneous generation
of electricity and steam which will create unquestionable
operational synergies between both utilities factories.
Thus Galp Energia will take a more a decisive step in the
modernization of its refi ning apparatus making it more energy
effi cient, better integrated with its environmental surroundings
and more competitive to embrace in a more sustainable
manner a new lifecycle starting in 2012.
As happened in the previous cogeneration design for Sines
refi nery, this new cogeneration center managed to obtain,
from the European Investment Bank (EIB), a signifi cant increase
of funding that is a mark of credibility to the project and a
prize by the rigor with which Galp Energia promotes, manages
and implements this kind of investments in its industrial core
business.
In addition to all benefi ts to the refi ning facilities, these new
cogeneration power plants will create both value in Gas &
Power, by adding new volumes of natural gas and by the use
of gas in the effi cient generation of electricity which will be
delivered to the public electricity network, that in the case of
Matosinhos refi nery, is operated by EDP Distribution.
The signifi cant steam consumption in the process of refi ning
along its continuous operation regime, makes Matosinhos
refi nery an excellence site for implementing the cogeneration
technology and thus driven by the Utilities Factory team, this
project gathers all the conditions to confi rm the good results
already achieved in the Sines Cogeneration and also contribute
to the success of this Galp Energia strategic industrial complex.
MATOSINHOS REFINERY / DATA BOOK ON HEALTH, SAFETY AND ENVIRONMENT 2011
The design of the new Cogeneration Plant
The new Cogeneration Plant consists of two gas turbines,
industrial type of General Electric, model Frame 6B equipped
with combustion chambers Dry Low NOx (DLN ENTERPRISES)
with a nominal electrical power of unit 41 MWe. This model of
gas turbine engines, industrial design (Heavy Duty), has more
than 1000 references worldwide of which, several hundreds,
are installed in the industry of Oil &Gas.
Gás Turbine GE Frame 6B (DLN)
Gas turbine technical data:
• 17 stages bolted axial compressor;
• equipped with Inlet Guide Vanes (IGV);
• combustion chamber consisting of 10 annular elements;
• NO x emissions: 15 ppm (15% O2) for natural gas;
• turbine 3 stages of screwed connection.
The two gas turbines are attached to two recovery boilers
(Heat Recovery Steam Generators) that use the thermal energy
contained in exhaust gases to produce steam for the refi nery.
These boilers have natural gas post-combustion burners that
using the exhaust gases as oxidizing, allow to modulate the
steam unit production (@ 66 barg and 450ºC) since 85 ton/h
(minimum) up to 130 ton/h (Maximum Continuous Rating),
keeping unchanged the electricity production of the gas turbine
that is attached to each boiler.
Additionally the boilers are individually equipped with fresh-air
systems which allow to maintain its operation in case of
breaking down the Gas turbine. The boilers are manufactured
by NEM that supplied in Portugal the combined-cycle recovery
boilers of Tapada do Outeiro and Carregado.

3D model of the new cogeneration center
Cogeneration center technical data:
• 2 x GE Fr6B DLN + 2 x NEM HRSG (eq. c/ PC & FA);
• nominal heat output: 82 MWe (2X41 MW e );
• steam generation capacity: 260 ton\h (@ 450 C, 66 barg);
• electricity production: 670 GWh\year (forecast);
• steam production: 1.6 megaton Tsar/year (forecast);
• natural gas consumption: 232 Mm 3 (n)/year (forecast);
• equivalent electrical effi ciency (REE): 75%.
Under normal operation, the new Cogeneration Plant will
produce the equivalent of about 70% of the electricity
consumed in the municipality of Matosinhos with an equivalent
(REE) electrical effi ciency of 75% (this value compares with
the electrical effi ciency of a combined cycle power plant,
which is currently 60%) which shows a primary energy savings
exceeding 15%, and a reduction of CO 2 emissions at national
level of 400,000 ton/year.
Based upon these effi ciency values, the new power of the
refi nery of Matosinhos is classifi ed, according to the Community
Directive 2004/8/EC, as “high effi ciency” cogeneration.
Interconnection of new combined heat
and power plant with the external energy
infrastructure
The construction of New Combined Heat and Power meant
new interconnections of the Industrial Plant to high pressure
natural gas network and high voltage electricity distribution.

is a substantial stake in the refi nery in measures aimed at
reducing the impact of pollution produced. It is emphasized
that the adoption of inline technology often means technical
and structural constraints that prevent the implementation of
integrated technologies of pollution prevention as desired.

4.3 Training in Health, Safety and the Environment
The training policy of Galp Energia seeks to ensure employees
personal and professional development, aiming to contribute
to the consolidation of the group’s culture, promote the
development of strategic perspective on value creation,
supporting the individual development plans.
The themes of Safety, Health and Environment, especially in
an industrial activity as the refi ning, are absolutely strategic,
and over the past few years the cultural development of the
Organization has made clear its commitment to training and
qualifi cation as essential tools in ensuring sustainability of the
activity in its various strands. Training plays a key role and
therefore is taken with great seriousness at the refi nery and
between employees and service providers.
The realization of this vision unfolds in two parts. The fi rst
focuses on the training and qualifi cation of employees of the
refi nery and takes several available formats: on-job, classroom
or e-learning, packing various learning processes.

Matosinhos refi nery as a way to keep ensuring that the
procedures and rules are understood and to assure everyone’s
commitment, provides since a long time through internal
resources, communication and training sessions of various
kinds, which are mainly distributed by fi ve groups: hosting,
training, awareness, warning and Emergency Brigade either to
internal employees or to service providers employees.
In 2011, 516 training courses were provided distributed by the

Except for the Emergency Brigade training, the set of trainings
now under consideration are not programmable, and are given
according to the circumstances and events occurring each year,
such as for instance the technical shutdowns for maintenance,
which somehow explain the change seen over time, recorded
in previous graphs.
The training, warning and awareness courses are distinguished
mainly by their purpose.
The fact that the refi nery intends to raise and adjust the
performance indicators with the best available references
requires that, whenever deviations to indicators are identifi ed,
awareness campaigns are promoted to warn and start
improvement actions.
In turn, the continuous improvement of procedures, practices
and routines requires training as a way to bind throughout the
organization the general knowledge of the processes of change.
The failure of procedures, adoption of unfair practices or
performance of unsafe acts, requires the completion of
warning actions as a way to ensure non-recurrence of these
attitudes in future behaviors.

The percentage differences between the years 2010 and 2011,
respectively 45% and 34% are due to the fact that the year
2010 endured a technical shutdown, which meant access to a
large volume of employees in the facilities in that year.

Monitoring air quality
Matosinhos refi nery focuses heavily on minimizing the
environmental impact of its business, and these efforts are
shown in the development of its key indicators and the high
level of investment to improve the industrial plant.
In this guideline, between March 2010 and December 2011 a
comprehensive study to assess the air quality surrounding the
refi nery was carried out. This study emerges from the concern
that was expressed by the Commission for Coordination

Toluene is an aromatic hydrocarbon insoluble in water with a
typical odor of paint solvent. Chemically, it is a mono-substituted
benzene derivative i.e. that presents one of the hydrogen
atoms of the benzene ring replaced by CH 3 group. Toluene
occurs naturally as a component of various petroleum products,
being widely used as industrial raw material and as a solvent
for paints, coatings, glues, oil and resins.
The term xylene refers to a set of three isomers closely related
with benzene (Ortho-, meta-, and para-xylene). Xylene is a
colorless aromatic hydrocarbon, with sweet odor and highly
fl ammable. The Ortho-xylene (o-xylene) is the only form of
naturally occurring xylene; the other two are forms of human
manufacture. The XYLENES are used in gasoline and as a
solvent in printing industries, rubber and leather. P-xylene is

Benzene is a colorless and highly fl ammable aromatic
hydrocarbon, slightly soluble in water, with a sweet smell and
a relatively high melting point. Being a known carcinogenic,
its use as a component of gasoline is currently limited to 1%,

The study of air quality assessment was conducted by the
Institute for Environment and Development, an organization
widely recognized for its technical and scientifi c excellence in
environmental matters and was monitored by several offi cials,
including the CCDR-N that led, the Directorate General for
Energy and Geology, the Portuguese Environment Agency, the
General Inspectorate of Environment and Territory Planning and
the City of Matosinhos.
The legal framework for air quality is established by Decree-Law
No. 102/2010 of September 23 rd , which sets out goals for
ambient air quality taking into account the standards, guidelines
and programs of the World Health Organization, designed to
avoid, prevent or reduce emissions of air pollutants. It establishes,
in particular for benzene, the limit values and thresholds, as this
is the only hydrocarbon covered by national law.

102/2010 defi nes minimum time coverage for indicative
measurements of benzene a value of 14%, corresponding to
eight weeks distributed throughout the year. In order to comply
with the minimum sampling, it was decided to hold a series of
13 campaigns, 5 of which in 2010 and 8 in 2011.
We established a sampling grid covering a total of 59
measurement points, covering an approximate area of 35 km 2
in the nearby surroundings of the refi nery.
The location of sampling points can be viewed in the following map.
Sampling points location
MATOSINHOS REFINERY / DATA BOOK ON HEALTH, SAFETY AND ENVIRONMENT 2011
The sampling methodology adopted, resulting from the use
of passive diffusers, allows to know the spatial distribution
of pollutants monitored, enabling the identifi cation of any
contaminated areas, or the recognition of unknown emission
sources.
The air quality monitoring campaign using the technique of
passive gaseous compounds was performed using Radiello ®
diffusion tubes.
They were placed on power or lamp posts at a height of about
2.5 m, avoiding wherever possible locations near intersections,
bus stops and other “hot spots”.
Sampling of benzene, toluene and xylenes was performed by
using passive diffusivity samplers of activated carbon, allowing
adsorption of the compounds at a constant speed during
the period of exposure to ambient air, which corresponded
to a volume of air samples. Following their collection the
samples were sealed and sent to laboratory for analysis by gas
chromatography.
In turn, NO 2 and SO 2 sampling was performed by using passive
diffusivity samplers of triethanolamine which are laboratory
analyzed by ionic chromatography technique in the form of
nitrite ion and sulfate ion, respectively.
In terms of data processing, and as a means of determining the
annual concentration average over a calendar year, as required
by law, the average of the 2011 eight campaigns was made,
of the results of each point, which were compared with the
legal limit of 5 μg/m 3 .
The statistical treatment of results reveals the following:
Average: 3.0 μg/m 3

The results were collated in the form of bar chart, which is

of the results fall between 1 and 3 μgrams with only three
points above 10 micrograms. Just one point, located at Rua
Coronel Helder Ribeiro near the WWTP, shows over 5 μg/m3.
All points installed in sensitive inhabited areas located north,
south and east of the refi nery have average concentrations
below 5 μgrams/m 3 .

The assessment study of ambient air quality in the Matosinhos
refi nery surroundings, now presented, shows that there
are no concerns with the concentrations of benzene in the
monitored metropolitan area where the refi nery is located. It
also corroborates the measurements that the public station for
monitoring air quality, located in Perafi ta (see www.qualar.org),
about 1.5 km north of the refi nery, has been presenting.
Nevertheless, the refi nery, aware of its commitments to
protect the environment and the relentless pursuit to improve
its performance, will continue to monitor the air within the
limits of the facility, either with passive samplers, or with
its own stations for continuous monitoring that have been
acquired in the meantime.

The Boa Nova shipping area has a set of 46 tanks, which store
and dispatch the products to the whole country, supplying
about one third of the national market needs, and also from
where it exports to europe part of the petroleum products
produced in the Matosinhos refi nery complex.
This activity covers the receiving, subdivision and shipment by
road tankers of several product families, such as:
• aromatic and solvents, for national and international chemical
and petrochemical industries;
• petrol and Diesel, to supply fuel for the entire north area of
the country. In these facilities, they are coloured and additives
are added according to performance requirements and legal
marking;
• fuels, for the energy supply of part of the portuguese industry;
• paraffi ns, which are used in several industries , e.g. candles,
cosmetics, moulds, food, etc.;
• bitumen of various grades, as a component for industrial
adhesives, binders and insulation wire but essentially for road
paving;
• JET A1 (in cases of contingency, it is possible to supply
aviation fuel to domestic airports from this facility).

Under the Decree-Law No. 194/2000 - Integrated Pollution
Prevention and Control (IPPC Directive) - Matosinhos refi nery
holds an Environmental Permit (No. 190/2008) which
systematizes and meets all legal environmental requirements.
In addition to this license Matosinhos refi nery holds a
greenhouse gas emission permit, TEGEE n. 197.05.II in the
amount of 1,098,095 CO 2 emission permits in 2011.
On November 2011 Environmental Permit no. 190/2008 has
been replaced by Environmental Permit no. 190/0.2/2011.
All data concerning 2011 are thus presented according to
limits set in Environmental Permit no. 190/2008 as well as
the limits and/or considerations of Environmental Permit no.

7.1 Resource consumption
Given the signifi cance of its use as well as its environmental
signifi cance, this chapter presents information and indicators
relating to water consumption and energy.
Resource consumption
The water that Matosinhos refi nery uses for industrial purposes
comes from Água do Noroeste and INDAQUA (used for human
consumption and exceptionally in industrial activities) and may
also come from surface water catchment of the River Ave (ETA
Vilarinho), to be used in the industrial activity, including cooling
and steam generation processes. The fi rst two sources are
considered to be potable water.
The following graph shows the water total consumption, as well
as the amount of recycled water from the Industrial Wastewater
Treatment Station (WWTP) and then reused.

The year 2011 followed the trend of recent years in terms
of gradual reduction of fresh water consumption, noting a
decrease of 2% over the year 2010. Simultaneously, there
was the reuse of 891,206 m 3 of treated water, in line with the
previous year, taking advantage of the storage infrastructure
created in 2009. Actually in 2009 an investment to build a new
fi re water tank was made - TK4504. This new water tank allows
the storage of more recycled water from the WWTP.
MATOSINHOS REFINERY / DATA BOOK ON HEALTH, SAFETY AND ENVIRONMENT 2011
This chapter presents information and indicators concerning
Matosinhos refi nery’s environmental performance, including
compliance with IPPC Directive and further best practices.
These indicators are presented both in absolute and normalized
terms, ie, disregarding scale effects arising from different
levels of activity intensity. Indeed, the level of activity in the
installation inevitably infers absolute assessment indicators,
sometimes without the absolute evolution providing a good
picture of the progress and performance of the facility.
Moreover, standardized indicators ensure also a comparison of
the refi nery’s performance with its european peers within the
same reference sector.
The reuse of treated water from the WWTP enables to decrease
markedly the use of make-up fresh water and reduce the volume
of treated water sent to the receiving environment, the sea.
The chart below shows the evolution of water consumption by
level of activity.

In 2011, despite the refi nery having operated at a higher level
of activity than in 2010 and given the increase of complexity
of processing raw materials, there was a decrease in water
consumption, a fact that refl ects a better effi ciency in the
management of water resources and which resulted in a
decrease of 2% in the indicator of water consumption by level
of activity in the previous year.
Energy consumption
Indicators of energy consumption consider fuel and electricity
consumption.
Fuels consumed in the refi nery are the Residual fuel oil
(known as RFO) and gas, a mixture of fuel gas enriched with
natural gas. This allows an increased amount of gas available
for consumption, making it possible to reduce consumption
of a less clean fuel, as the RFO. Matosinhos refi nery has
progressively privileged consumption of clean fuels.

Since the entry of natural gas into the refi nery’s fuel pool,
in 2008, it has been observed a signifi cant decrease in the
consumption of RFO, as it may be verifi ed in the charts.
In 2011, RFO consumption has decreased about 11% compared
to consumption during the year 2010. This decrease is due in
part to natural gas increased consumption in 2011 which was
79,064 tons, compared to 45,338 tons consumed in 2010.
As far as electricity is concerned, the refi nery sells or acquires
electricity from the city network depending on whether there
is surplus or shortage. The following graph shows the electricity
produced and consumed.

Sulfur is a natural component of crude oil. During the refi ning
process it is possible to recover a great part of this element, but
a residual portion is retained in refi ned products. When these
are used as fuel, sulphur is released into the atmosphere.

In order to reduce SO 2 emissions, the refi nery has been making
an effort whose notorious impact can be evidenced in the two
previous graphs. On one hand, natural gas was added to the
portfolio of fuels used and increased the consumption of fuel
gas, undoubtedly contributing to the reduction in emissions. On
the other hand, it is also clear the use of RFO with a sulphur
content quite inferior to the limit stipulated in our permit (3%),
with a favourable impact in our 2011 SO 2 emissions.

Finally, it can be seen below the evolution of the SO 2 “bubble”.
This indicator shows the concentration of sulfur oxides in a
virtual chimney, weighting the smoke fl ow and the pollutant
concentration in several sources.
Matosinhos refi nery has made a great effort in the continuous
improvement of its performance in this area, as illustrated in
the chart. Also, through this indicator, it’s visible the result from
the use of cleaner fuels, including the privilege given to the
consumption of gas and RFO with low sulphur content

As far as NO x emissions are concerned, it is noticeable
the success of Matosinhos refi nery towards a continuous
improvement of its environmental performance, due to the
increased consumption of gas against RFO and by installing low
NO X burners in the main fi ring facilities.

2011
Regarding particulate emissions, in 2011 there is a 30%
increase in particulate emissions, compared to the previous
year. This increase is justifi ed by the increased level of activity
observed in the refi nery during the year 2011 compared to
2010, when there was a technical shutdown of the refi nery in
October and November.
Despite this increase, emissions remain at lower levels when
compared to those observed prior to the introduction of
technical measures to reduce this pollutant. As can be seen,
the quality of fuels burned, like gas, and the installation of
an electrostatic precipitator were decisive factors in reducing
emissions from the end of 2008.
Carbon dioxide
The following graphs show CO 2 emissions deriving from
Matosinhos refi nery’s activity and evidences the suffi ciency of

reduction in all of the sectors covered by this regime because
since 2008 the collective ceiling includes the Aromatics Plant.

Volatile organic compound
Matosinhos refi nery’s volatile organic compound (VOC´s)
emissions come from various sources: product storage, process
(including the drainage network) and effl uent treatment.
Matosinhos refi nery carries out VOC´s monitoring campaigns,
under its Leak Detection Repair programme, whose
measurements allow the minimisation of fugitive emissions.
In these campaigns, the total emission of VOC´s resulting from
the refi nery operation is calculated, taking into consideration
fugitive emissions that result from leakages in manual and
automated valves, pumps, exchangers, fl anges, sampling
points, vent, purges and other end-of-line equipments.
The VOC’s emissions also include the drainage network and
equipments placed in the storage area (such as fugitive
emissions) and the fugitive emissions of the different
treatment equipments of the WWTP.
The European Standard EN15446:2008 is being used to
calculate the escaping emissions, associated with the different
process equipments and the drain pipe system - “Fugitive
and diffuse emissions of common concern to industry sectors.
Measurement of fugitive emission of vapours generating from
equipment and piping leaks”.
To quantify diffuse emissions from the WWTP the EPA
programme Water9 is being used and diffuse emissions from
storage the software TANKS 4.09D is being applied.
These procedures implemented under the Leak Detection
Repair programme, follow the techniques defi ned in the
reference document under the IPPC: reference document on
best available techniques for mineral oil and gas refi neries
(BREF 4.23.6.1.)
Continuous monitoring
Matosinhos refi nery carries out continuous monitoring of
SO 2 , NO x and particulate matter at several fi xed sources.
Nevertheless, under the environmental permit it is only
mandatory to continuously monitor the process furnaces fed
with RFO and gas – mixed sources.
The following graphs show the results for the SO 2 , NO X and
particulate matter, over the analysis period, for the self control
of the three mentioned fi xed sources.

7.3 Wastewater
Wastewater production
As mentioned in previous editions of the Data Book, the
wastewater production is inherent to operations, but is strongly
infl uenced by the meteorological conditions, as rainwater in the
processing and storage zones is collected and conducted to the
refi nery’s WWTP.
The commitment of the refi nery to reduce the impact of its
operations, developing continuous efforts to ensure sustainable
integration in its surroundings and operating its assets at levels
comfortably below the Emission Limit Values (ELVs) set, is clear
from analyzing the above graphs. The values of the ST0601
source referred to August are due to the Aromatics Plant
shutdown that happened in that period for economic reasons.
It should be pointed out that since 2008, Large Combustion
Plants (LCP’s) have been subject to a mass ceiling, as defi ned
in the National Emission Reduction Plan (PNRE). The changes
in recent years in pollutants mass emissions are visible in the
following graph:

As can be observed from the analysis of the previous charts, in
recent years it is notorious the refi nery’s effort to reduce the
production of waste which is not likely to be recycled given the
amount of recyclable waste.
As far as the amount of industrial waste that can be recovered
is concerned, the refi nery’s performance depends on the
completion of work carried out by third parties, and the
activities undertaken. Actually the vast material recovery in the
year 2010, as in 2007, was due to a technical shutdown for
maintenance, having been produced large quantities of metallic
scrap arising from the replacement of equipment.

Work accidents are a cause for concern, so it’s a prime task of
Matosinhos refi nery Management to ensure the existence of
the conditions, procedures and practices designed to prevent
occurrences and implement all preventive and corrective
measures to prevent recurrences.
04
Within the implementation of the Health, Safety and
Environment Systems of Galp Energia Group - the G+ System,
all accidents occurring to own or to third party workers during
the execution of services assigned to them, are investigated in
order to identify corrective and appropriate preventative actions
to prevent them.
In 2011, there were 27 accidents in the refi nery, involving
direct workers, as illustrated in the following graph.
Of the 27 accidents, 25 were cases of fi rst aid and 2 were
cases of medical treatment, with no accident with lost workday
injuries.
It should be noted that, although in the year 2011 the number
of occurrences is higher compared to the year 2010, the fact
that we have registered a value of 93% of fi rst aid accidents
shows a very signifi cant declining trend in relation to the
severity of injuries.

Statistical analysis and reporting of the frequency rate of
accidents involving lost workday injuries by most petrochemical
companies at European level, allows the reference benchmark
for this sector. For the year 2011, the value taken as a
reference to a calculation that includes accidents of its own
staff and contractors was 2.2 for this branch of industrial
activity according to the 2010 Concawe’s report.
This reference makes it possible to assess the degree of
performance of Matosinhos refi nery that comparing its
frequency rate of 0.9 is positioned securely at the level of the
best companies in this activity sector as far as accident rate is
concerned.
Inseparably from the frequency rate, the severity index must
be considered, once this one expresses the number of lost
workdays resulting from the type of injury for each accident
with lost workdays.
The 3 accidents that resulted in lost workdays in all contractors’
workers were refl ected in the severity index, as shown in the
graph below. In 2011 and including all universes (refi nery and
contractors) the severity level was 15.

In addition to investigating accidents at work the refi nery also
investigates all incidents including material, environmental,
road accidents and near misses. Particularly the analysis of
the latter reveals a huge potential for the improvement of the
plant’s safety.

2011 was characterized by the absence of environmental
accidents. However as far as material accidents are concerned
on August 11, during the startup of the new units, there was an
internal outbreak in an acidic water storage tank, which caused
the ceiling burst, without consequences for people, facilities or
the environment.

8.2 Occupational medicine
Occupational medicine in Matosinhos refi nery operates with
a view to the promotion of the health of workers and the
prevention of occupational diseases. For this purpose a periodic
plan of examinations is performed throughout the year, as
well as for the admission of new workers and occasional
examinations either on the initiative of the occupational
physician or the initiative of the employee.
The following chart illustrates the number of medical
examinations performed in Matosinhos refi nery during the
period 2007 to 2011. For 2007 only aggregated information
is available – total accident, while for other years it is already
possible to segregate the number of examinations depending
on its type.
A total of 916 medical examinations were held in 2011
including admission, periodical and occasional examinations.
There is an increasing number of scheduled examinations in a
clear demonstration of good planning for this activity.
Annual observation
Matosinhos refi nery, a top level dangerous industry considering
the quantities and characteristics of the products stored,
according to the provisions of Decree-Law No. 254/2007, of
July 12, implemented a safety management system for the
prevention of industrial accidents (SGSPAG) that allows the
confi rmation that the existing measures for the prevention and
mitigation of major accidents involving dangerous substances
are suffi cient and appropriate.
Accordingly, since 2008, audits are carried out annually by
qualifi ed auditors of the Portuguese Environment Agency (APA).
These audits through the issuance of Statements of Compliance
have confi rmed that the refi nery of Matosinhos complies with
the legal safety requirements and operates based on sustained
principles of environment valuation and safety of installations.
In 2011, the result of the audit identifi ed two “Non-compliances”
(NC) and two “Opportunities for improvement” (OI).
The number of non-compliances that have been identifi ed
in the period between 2008 and 2011 is presented below.
Non compliances are defi ned as improvement opportunities
for what and for each one of them an action plan is defi ned
containing measures to eliminate the root causes.

Implementing a Management System for Safety, Health and
the Environment requires, among other guidelines, the means
to measure its outcome. The performance of Preventive Safety
and Environmental Observations (OPAS), assumed as the act of
to observe, talk and register as a means to correct actions or
dangerous situations, is one of the indicators used to assess the
effi ciency and ascertain system guidelines
Matosinhos refi nery established the annual goal of 840 hours
of OPAS, however, that goal has been being exceeded over the
years, as shown in the following chart. In 2011, 992 hours of
OPAS were completed.

The refi nery is fi rmly committed in the approach with the
surrounding local residents in order to meet their needs and
concerns. For this purpose, an email address was created,
refi nariamatosinhos@galpenergia.com, which allows dealing
with situations like complaints, suggestions, among others, in a
more expeditious and methodical way. In 2011 there were no
records at this address.
This initiative aims to appropriately give a response to the
progressive enrichment of the population of Matosinhos
with particular emphasis to the surroundings of the refi nery,
ensuring that this installation does not introduce factors that
jeopardize the quality of life of the city and its inhabitants.
This way the Refi nary seeks to develop initiatives that
contribute for the above purposes. For 2011 we point out the
following:
Open refi nery
Between the 28 th and the 30 th September the refi nery opened
its doors to the outside citizens. We were rewarded with the
visit of hundreds of people interested in knowing the “inside”
of a refi nery. A reception tent was installed in the Leça da
Palmeira marginal, near the well known Tidal Pool by architect
Siza Vieira and buses were made available to visitors to travel
through the main streets of the refi nery
School visits
Integrated in school projects, or just as an opportunity to
extend knowledge and experience of an industrial site in full
operation, we are visited annually by hundreds of students
of various levels of education. To these students and their
teachers, a brief presentation of the refi nery and its products is
made, complemented later with a bus tour to the main spots
of the refi nery. In 2011 we were visited by about 800 students.
Protocols with schools
The refi nery has concluded agreements with several schools in
the municipality of Matosinhos, including the EB Perafi ta School,
the EB Leça da Palmeira School and the Secondary School of
Boa Nova. Under these protocols the refi nery contributes with
funds to equip laboratories, to carry out minor improvement
works of education facilities, and to develop projects such as
school-radio.
The refi nery allocates annually the Galp Award for the best
student in the 9th grade of EB schools and the best students
in Physics and Chemistry for High School. The refi nery is also
committed to receive interns from courses in professional
areas of which we highlight occupational health and safety
technicians and the environmental technicians.
Also as part of a technical training, the refi nery has protocols
with professional schools in order to guide the training needs
of industry, while ensuring job opportunities for students when
recruiting employees.
MATOSINHOS REFINERY / DATA BOOK ON HEALTH, SAFETY AND ENVIRONMENT 2011
Finally, within the chapter on safety awareness, several
technicians from the refi nery, experts in Health, Safety and
the Environment have collaborated with several high schools
in the municipality of Matosinhos disclosing to young students
messages inducing safe behaviors.
Social Responsibility
The refi nery as a member of the community cannot be kept
apart from the diffi culties that the most disadvantaged sectors
experience in this period of economic contraction. Accordingly,
we made donations to various charities and associations for
the elderly, participating in the purchase and distribution of
equipment useful for the welfare and quality of life of patients
and the elderly.
Striving to attend situations of need in the social tissue of
Matosinhos, in collaboration with the parish councils and the
church, the refi nery has been at christmas with the most
disadvantaged families, and associations that support them,
helping to make this a time of great solidarity.
The refi nery also promotes recreational and sports events to
support sports at local clubs.

“Recovered sulphur”, and the load processed.
Recycled water Represents the quantity of treated water in the WWTP of Refi nery that is reuse in the water fi re network and in
the service water network.
RFO Consumption Consumption of Combustible Process Waste (Fuel-oil for internal consumption), for burning in LCP´s and process
furnaces.

SO 2 emissions This indicator represents the sulphur dioxide emissions arising from RFO combustion LCP´s and in process
furnaces, in the AP and in the Claus Unit. The combustion emissions are calculated using the following formula:
SO 2 Emissions per level of
activity
SO 2 = SO 2 RFO (t) = Consumption RFO (t) x % S RFO x 0,02
% S RFO represents the level of Sulphur in the RFO (See “Sulphur content in the RFO”). Emissions of SO 2 from the
Fuel Gas and Natural Gas are not considered as the level of Sulphur is very close to zero.
Beginning April 1 st , for fi xed sources with continuous monitoring, the calculation of emissions switched to
being conducted by the Centralised Environmental Information System (SIAC - Sistema Informação Ambiental
Centralizada).
Means the ratio between SO 2 emissions, accounted for according to the contents of “SO 2 Emissions” and the
treated load.
SO 2 ”bubble” Represents the concentration of sulphur oxides in the form of sulphur dioxide, a virtual stack, weighing the
various fl ow rates and concentrations of different sources, as well as their sulphur content. The formula was
approved by the Portuguese Agency for the Environment, and excludes emissions from the Claus unit and
Flares.
Sulphur content in the
RFO
Means the percentage value of sulphur content in RFO. This value is determined in the laboratory, through
weekly analyses on compound samples, the annual value constituting a weighted average of the mean
monthly values.
Total Iron Represents the concentration of Iron in wastewater in accordance with the laboratory analyses conducted in
the Refi nery Laboratory.
Total Suspended Solids Corresponds to the concentration of Suspended Solids in the wastewater, in accordance with the laboratory
analyses conducted in the Refi nery Laboratory.
Wastewater
per level of activity
Wastewater
produced
Waste produced considered
solid urban waste
Water consumption per level
of activity
Means the ratio between wastewater produced, accounted for according to the contents of “Wastewater
produced” and the load processed.
Involves the volume of wastewater produced. m 3
Means the quantity of domestic or similar waste produced, due to its nature or composition ton
Represents the consumption of process water in the plant (captured from the Ave River), as well as water for
human consumption from the Matosinhos Municipal Water and Sanitation Service
