The following graph allows the evaluation of the specifi c
emissions of particulate matter at Matosinhos refi nery:

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

2011 was the fourth year of the second compliance period of
the Portuguese National Emission Allocation Plan, PNALE II –
2008-2012. The change in the number of emission allowances
recorded from 2007 to 2008 does not refl ect the generalized
reduction in all of the sectors covered by this regime because
since 2008 the collective ceiling includes the Aromatics Plant.
Although there is an increased consumption of gas, instead of
RFO, with higher carbon content, CO 2 emissions increased in

2011 compared to 2010 due to the increased level of activity
recorded during 2011 and a larger number of operating hours
of the 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.
