Advantages for system integration
Growing pressure on the production side, ever shorter product life-cycles,
rising production demands and an ever greater complexity. On the one
hand, the end customer demands for you as a system integrator are
immense. On the other hand you require solutions, which let you execute
and engineer your customer projects more quickly, precisely and economically
– from the design to commissioning.

Competence for the processes in the Chemical Industry
To ensure economic success in the chemicals business, you
need top productivity, highest flexibility, maximum safety
and the efficient use of resources in all your production
processes. This is the only way to meet the demands for fast
delivery, high and constant quality, and competitive prices.
Typical process units in chemical plants
The reaction process is at the heart of chemicals production,
and the greater the efficiency and performance of the catalyst,
the better the product yield and quality. To ensure the best
possible results, key process parameters such as temperature,
pressure and flow must be controlled with great precision.
When process media are being warmed or cooled, it’s crucial
for heat exchangers to quickly and precisely reach the right
temperature. At the same time, of course, it’s important to
prevent any contamination or unnecessary energy loss.
Using the best possible extraction agents, together with
seamless integration of heat with downstream columns,
brings long-term cost savings in extraction while maximizing
product quality and minimizing environmental impact.
Two key parameters determine the economic efficiency of
the distillation process: how much energy is used for vaporization
and condensation, and – as with heat-sensitive
substances, for example – whether environmental conditions
can be completely controlled.
Successful, efficient absorption of gaseous product mixtures
depends on selecting the right absorbing agent and controlling
all process parameters. High process and product
quality can only be achieved when all factors are optimally
combined and coordinated.
Tailored to the demands of the Chemical Industry:

at the same time
Comprehensive fieldbus integration makes the connection
of field devices easy and optimizes the handling
Direct interfacing to the IT system opens the DCS.
Maximum plant availability, with overall
redundancy through all levels
Availability is one of the most important criteria in a chemical
production, and consequently the availability of the automation
solution itself plays a key role in the economical effectiveness
of the plant. On the one hand the capital investment
for a chemical plant is extremely high, and on the other
hand, any production loss due to shut-down and start-up
operations can imply huge economical loss. Plant shut downs
must then be avoided as far as possible – with periods usually
reaching from once a year to less than one shut-down every
5 years for example for a steam cracker.
To guarantee the highest availability of the automation
system, all system facettes have to be taken into consideration:
starting from the controllers up to the operator level
and including the whole plant communication networks,
from the field to the production control level.
Redundant OS clients and
SIMATIC BATCH clients

Distribution with SIMATIC ET 200iSP in hazardous areas
In most companies, time and cost pressures belong to everyday
life. Increasingly shorter production times and reduced
costs are requested in all operational areas. In order to
manage these demands, many users in the process and
production industries apply distributed solutions, with remote
I/O devices allowing sensors and actuators to be connected
to a bus system in a cost efficient way.
Cabling costs and the number of standard terminal blocks,
junction boxes, IS barriers, which are normally used, are
clearly reduced. PROFIBUS has become the standard fieldbus,
also extending into hazardous areas.
The SIMATIC ET 200iSP (iSP stands for intrinsically safe for
process industry) from Siemens is a modular, intrinsically
safe I/O system with IP30 degree of protection for hazardous
areas. It can be used both in gaseous and dusty atmospheres,

which switch the motors up to 7.5 kW. By means of PROFIBUS,
the motor starter reports diagnoses, for example short-circuit,
phase asymmetry, operating current or overload, to the
control system. This helps to reduce downtime costs by a
quick and detailed diagnosis.
industrial communication for plantwide automation
The business drivers in industrial communication are improved
efficiency and safe data transfer in the plant. These
criteria are crucial to ensuring that process in your plant
works perfectly. This can be achieved by using open, transparent
communication not just on the process level, but
also through ERP systems.
The SIMATIC NET industrial communication products provide
the technology you need to:
Realize true distributed automation

Support for redundant I/Os in conjunction with
OPC server included with the communications
communication for sensors and actuators
Sensors and actuators play an important role in automated
processes. Whether it concerns the detection of valve states
or the correct level in a reactor or tank: sensors are the eyes
and ears of process control.
For a long time the cabling of transmitters and recorders
followed the old pattern: each sensor or actuator was
connected individually and with parallel wiring to the higherlevel
controller. Because the AS-Interface now provides you
with a bus system that implements the connection of all
automation nodes in the field to the higher-level controller
– simply, securely and cost-effectively. The AS-Interface
transmits process-level digital and analog signals and
connects proximity switches, valves, indicator lights and
other actuators and sensors to the higher-level controller.
Drive systems: reliable, precise and efficient
In many applications in the Chemical Industry, the use of
frequency drives to regulate motor speed makes drive
technology more efficient. Variable speed allows much
more precise control of processes, such as the transport
and dosing of products, and at shorter response times than
do mechanical control concepts. In addition, soft starting
and deceleration in the variable-speed mode goes easy on
the entire drive train’s mechanical components. This prevents,
for example, pressure waves in pipeline systems.
Unfavorable operating conditions, such as cavitation, parallel
transport of gas or solids, ultrasonic compression shocks
and vibration can be avoided by using a frequency converter.
Variable-speed mode also saves a very significant amount
of energy, particularly in applications involving quadratic
load torque, like fans, pumps and compressors, as compared
to fixed-speed motors. Depending on the plant characteristic,
energy savings may reach 50%. Because of this, a frequency
drive soon pays for itself, often within only a few months.
For the most part, variable-speed drive tasks in the Chemical
Industry are covered by MICROMASTER 440 frequency drives
and SINAMICS G150 frequency drives.
SINAMICS: the new drive family
All members of the new SINAMICS drive generation profit
from the same core technology and have the same ”look
& feel“. An example are the standard engineering tools –
SIZER to engineer drives and STARTER to commission them.
In addition, all high power cabinet units of SINAMICS are
equipped with an AOP 30 operator panel with its selfexplanatory
menu prompts, which are output in plain text
via the user-friendly graphic display. This permits extremely
simple operator control and diagnostics. For the Chemical
Industry with its pumps, fans, mixers and extruders, the
SINAMICS G150 cabinet units and the SINAMICS G130
chassis units are the primary choices for consideration.
MICROMASTER 440 frequency drives: packed with
functionality for a wide range of applications
Whether it involves mixing drives in conjunction with offset
shaft geared motors, agitators in hazardous areas, extruders
requiring a high starting torque or, for example, foil processing
machines where several drives run in synchronized
operation – our MICROMASTER 440 frequency drive is the
best selection where maximum functionality and higher
dynamic performance is demanded. Typical applications:
Transportation of fluids or gases and solid substances,
metering and mixing, filtering, extruding, lifting.
Specially for pumps, fans, compressors, mixers
The units are specially geared toward drive tasks without
regenerative feedback in applications with quadratic torque
characteristics, such as pumps, fans and compressors, but
also constant-torque drives such as extruders, mixers, mills
and conveyor belts.
SINAMICS G150 cabinet units cover voltage classes from
380 V to 690 V. Power ranges are from 75 kW to 1500 kW.
The clear, well-structured design of the SINAMICS G150s
makes the units rugged and reliable. In case of service, the
modules can be replaced in just a few steps.
Simple and user-friendly
Above all, however, the units are appealing thanks to their
user-friendly operation. Preconfigured and thanks to the
clear operating concept, customers take profit from
functionalities that they really need. The easy-to-use
operator and commissioning functions are shown on the
graphic display in plain text. In addition, SINAMICS G150
cabinet units have a footprint that is up to 70 percent
smaller than the footprint of conventional converters. Noise
levels of only 69 db(A) during full operation, even in the
case of cabinet units with a power output of several 100 kW,
make additional soundproofing measures unnecessary.
Demands of the Chemical Industry are fully satisfied
SINAMICS G150s fulfill all demands made by the Chemical
Industry. For example, the units are equipped with NAMUR
terminal blocks as well as NAMUR functionalities specifically
for the Chemical Industry. As alternative to NAMUR terminal
blocks, it is possible to use the PROFIBUS Profile PROFIdrive
3.1, ”Process Engineering“ mode. Safe electrical isolation
according to PELV is also ensured.
In order to restrict the steep voltage edges customary for
IGBT voltage source converters as well as phase-to-phase
voltage on the motor, dV/dt filters are available which limit
the voltage gradients. In addition, the phase-to-phase
voltage is also limited in the case of long motor wires. An
EMC filter for secondary environment category C3 to EN61
800-3 is integrated as standard. Sinusoidal filters are also
available for particularly high demands.
SINAMICS G150 covers the majority of drive tasks with high
power requirements. If required, the SINAMICS G130, a
chassis unit with the same functionality and performance,
is also available. SINAMICS S150 cabinet units and
SINAMICS S120 chassis units represent a viable alternative
when the energy supplier places particularly high demands
on the network quality or in the case of weak networks.
With these units, the active infeed technology reduces
phase effects on the system to a minimum and protects
the drive system against power dips. For drive tasks requiring
several megawatts – such as very big mixers or extruders –
SINAMICS GM150 medium-voltage frequency drives are
the most cost-effective solution.
Process instruments and analytics:
the full range for all measuring tasks
Siemens offers a broad product portfolio of process instruments
and analytics. All devices fulfill the needed certifications
in the Chemical Industry.
Throughout the Chemical Industry, measurement requirements
can be extreme. Every substance is different and
needs an individual solution. As the measurements are
often done in extremely harsh ambient conditions, specialized
process instruments (e.g. pressurized enclosures) are
often required for the relevant approvals (ATEX, FM, SIL,
Siemens process instruments offer advantages on the
automation level as well as for the asset management of
Continuous measuring or point level detection is based on
radar, ultrasonic or capacitive methods. From a storage
tank to stirring machines with high pressure, foam and
steam – with the product family SITRANS L and POINTEK,
we can fulfill the most common challenges in the level
Especially in the Chemical Industry, the tasks in measuring
the flow are versatile, just as our products are.
Magnetic-inductive and ultrasonic flowmeters or Coriolis
flowmeters are used for this. “Classical” mechanical methods
are also available: Rotary piston meters, variable-area
flowmeters, or measuring orifices remain an integral part
of our product family SITRANS F.
Whether high temperatures, high pressures, or aggressive
media, temperature measurement applications are not
always easy and are often done in harsh ambient conditions.
Our SITRANS T transmitters are available in different types,
from simple to intrinsically-safe with diagnostics and simulation
Whether relative, differential or absolute pressure, the
SITRANS P pressure transmitters provide precise pressure
measurements. The SITRANS P DS III instrument is ideal
where highly aggressive media and harsh ambient conditions
require experienced solutions and can be used for
safety-related measuring points in accordance with SIL 2.
The SIWAREX weighing systems can easily be integrated
into the automation structure of the process, and the
SIMATIC PCS 7 process control system. In addition to electronic
weighing systems and cells, you can select from an
extensive range of Siemens-Milltronics belt scales, weigh
feeders and solids flowmeters.
Reducing production downtimes is an increasing challenge
for a plant operator. Easy and versatile diagnostic functions
help to achieve these requirements.
To parameterize these functions, you can use our Process
Device Manager (PDM) software tool, usable for all field
devices. It facilitates the manufacturer-independent operation,
adjustment, maintenance and diagnostics of intelligent
process devices. Regardless of the automation system, it
can be applied via PC, or programming devices, or integrated
into the SIMATIC PCS 7 automation system.
With our SIPART PS2 valve positioner e.g., which is the most
frequently used intelligent positioner for linear and rotary
actuators, leakages at valve drives can be detected immediately.
A created warning message helps the maintenance
team to keep the process in optimized run.
The capabilities of modern process analytics can be the key
to a significant increase in efficiency, productivity, or safety
of chemical processes.
Continuous process analytics
The continuous gas analyzer of the Siemens series 6,
ULTRAMAT, OXYMAT, FIDAMAT, and CALOMAT, were originally
designed to fully meet the requirements for process analytics
in the Chemical Industry. Except for the FIDAMAT, based on
flame ionization detection, all analyzers are available in field
housings for operation in hazardous environments.
The intrinsic design of the analytical part of ULTARMAT and
OXYMAT and the materials in contact with the process gas
stream are chosen to withstand even highly corrosive gases.
Because the measuring system has no moving parts and
can be ordered in corrosion resistant materials like titanium
or tantalum the OXYMAT became the standard oxygen
analyzer in chlorine chemistry. Beside this, the excellent
analytical performance of the series 6 analysers make them
first choice in critical process applications in terms of
sensitivity and stability.
Optimized production of ethylene oxide
The efficiency of the ethylene oxide process increases with
the concentration of oxygen, while it is crucial to stay below
the lower explosion level (LEL). Due to its outstanding
stability, only the OXYMAT allows the process to be operated
at a set point of 5% O 2 , where competitive analyzers only
allow 4% O 2 . Thus, the process efficiency is increased by 1%.
Industrial controls and power distribution
More often the data of the motor feeders are also integrated
into the process control system. Intelligent motor management
systems, communication-capable motor starters and
circuit-breakers support this trend and make all relevant
data available via PROFIBUS. This increases the transparency
of your process and ensures a significantly greater density
of information in the control system – at no extra cost.
Standardized motor function blocks, for example, simplify
the integration and the engineering.
SIMOCODE pro: the flexible and modular motor
SIRIUS motor management and control devices (SIMOCODE
pro) are the first choice for constant speed motors in the
low voltage range. SIMOCODE pro optimizes the connection
between control system and motor feeder, increases the
plant availability and achieves considerable savings in the
construction, commissioning, operation and maintenance
of your plant.
It also involves an extremely compact design, a straightforward
and efficient service and maintenance as well as a
range of graduated functions. In addition, SIMOCODE pro
meets all requirements for future-proof energy management
and offers advantages in all areas: in process management,
operations management or in switchboards.
Some extensive features:
Multifunctional, electronic full motor protection,
independent of the automation system

ATEX-certified (overload protection of explosion-protected
SIVACON systems: for customized communication
SIVACON systems are low-voltage communication-capable
switchboards and busbar trunking systems with a high
degree of flexibility and availability. All of these features
provide a seamless integration into the automation environment.
Using switchgear and switching devices we offer a common
integrated communication concept for customized solutions:
e.g. with SENTRON circuit-breakers, SIMOCODE motor
management system and SIMATIC.
So SIMOCODE pro is likely to be used in SIVACON lowvoltage
Master Control Centers (MCC) and allows load
feeders to be configured. Load feeders that have a higher
performance and at the same time are extremely compact
and able to communicate.
The high degree of modularity allows all communication
components to be simply retrofitted. Innovative software
products offer user-friendly parameterization, diagnostics,
operator control and visualization locally via PROFIBUS DP
SENTRON: power distribution

of thousands of different combinations for all of your
energy distribution applications. The products in the
SENTRON circuit protection system tie into your automation
architecture giving you the power to increase production
system availability. In addition, you can further optimize
the energy distribution process with a networked power
management solution. Never before have circuit-breakers
been so versatile and so simple.
SENTRON: optimized energy solutions

SENTRON circuit-breakers can be done via the PROFIBUS DP
network. SENTRON circuit-breakers are completely integrated
into the SIMATIC world and the STEP7 engineering software.
Data management, configuration and programming is
integrated into the automation project SIMARIS manager
– Power Management Software to manage energy distribution
This modular and integrated power management software
is based on SENTRON switching devices and Totally Integrated
Automation. This not only facilitates efficient diagnosis,
alarm, and maintenance of SENTRON circuit protection
devices as part of a Totally Integrated Power solution but
also optimizes laboratory, investment and energy supply
costs through continuous analysis of energy data.
Best practice example:
INEOS Phenol production site in Gladbeck, Germany
INEOS Phenol is the world’s largest manufacturer of phenol
and acetone, with production sites in Gladbeck, Germany;
Antwerp, Belgium; and Mobile, Alabama, USA. In the course
of the company’s history, the Gladbeck site has experienced
significant development. The capacity of the plant at the
beginning of production in 1954 was a relatively modest
8,000 tons of phenol and 5,000 tons of acetone. Today,
Gladbeck is the largest phenol plant in the world, with an
annual capacity of 630,000 tons of phenol and 390,000
tons of acetone.
When INEOS was looking for a partner to modernize the
existing process automation system for the entire factory,
the company first performed an extensive comparison of
various control system suppliers. SIMATIC PCS 7, though
facing strong competition, was able to establish itself as
The INEOS order included replacement of all the installed
control technology on the entire site, with about 8,000
I/Os, and the merging of two control rooms. One decisive
factor for awarding the contract to Siemens, aside from the
previous positive experience INEOS had made with Siemens
in low-voltage projects, was the fact that PCS 7 offered a
modern, innovative, and efficient control solution that is
based on future oriented standards and Totally Integrated
Automation. The integrated safety technology and the high
system availability due to redundant solutions were also
decisive. In addition, PCS 7 offered the possibility of replacing
installed control technology during ongoing operation –
allowing the Gladbeck plant to continue to operate without
The new solution is based on a total of eight SIMATIC
S7-400FH automation systems. One redundant OS Server
and ten Clients plus one MultiClient as well as one
Engineering System were installed in the new control room
that resulted from merging the legacy system. The entire
plant was upgraded with no shutdown of production –
a very important aspect in high throughput continuous
processes such as phenol synthesis. The legacy systems
were changed over “loop by loop“, and the application
software of the legacy controllers was also converted.
The conversion from the previous control solution to SIMATIC
PCS 7 went smoothly, without interrupting plant operation.
With SIMATIC PCS 7, INEOS now benefits from increased
safety and system availability through redundancy on all
levels, and integrated fail-safe technology.
Best practice example:
Jilin Fuel Ethanol Co. Ltd., China
Jilin Fuel Ethanol Co. Ltd., a subsidiary of China National
Petroleum Corporation (CNPC), is a joint venture formed
by CNPC, Jilin Grains Group (JGG) and China Resources
Group. This project was the first plant dedicated to the
production of fuel ethanol from corn in China with a capacity
of about 600,000 tons of ethanol per year. The plant consists
of two production lines and the capacity of a single line is
300,000 tons per year. The first production line was started
on September 22, 2001 and was launched on August 31,
2003. This ethanol fuel pilot plant in China has become a
prestige project for the Chinese government.
This significance and the fact that the application is quite
large regarding the extension and the number of I/Os were
asking for a state-of-the-art automation solution. When
choosing the appropriate automation solution, high availability,
safety, and a future-oriented solution were central
criteria for Jilin Fuel, as was local expertise and know-how
for project engineering and maintenance.
Seamless integration of the safety technology, the great
openness of the system, an excellent price/performance
ratio of the concept, and last but not least the benefits of
the uniform automation solutions based on Totally Integrated
Automation tipped the balance in favor of automating the
plant using SIMATIC PCS 7.
The entire system, which comprises a total of 9,000 I/O
points, is controlled from two PCS 7 control rooms. Eight
safe and fault-tolerant S7-400FH automation systems and
two fully redundant optical Industrial Ethernet rings form
the reliable backbone of the control system. The system
also collects and transfers all production and units data,
including the corn storage facilities and other utilities, to
a real-time production monitoring system. The devices at
the process level are connected to the PCS 7 systems via
PROFIBUS DP fieldbus, using the fiber-optic technology to
bridge distances of up to 1100 meters on the plant field.
The production and process management has been optimized
and plant efficiency has been improved. Production
cost, such as materials cost and management cost, have
also been reduced.
The data management has become more transparent, with
the implementation of Manufacturing Information System
(MIS) and the web functionality at the operator-station
level. At the same time, the maintenance workload has
been reduced, due to the high stability and reliability of
the SIMATIC automation systems and components. At the
bottom line, product quality has been improved and now
meets one hundred percent of the market requirements.
Best practice example:
Bayer polycarbonate production facility in Map Ta Phut, Thailand
Global companies are increasingly relying on standardized
processes and systems – in order to exploit rationalization
potential for spare parts, training, and service across all
their locations. Bayer is no exception. The company-wide
specifications were recently implemented with the SIMATIC
PCS 7 process control system in the modernization of a
small batch line in Thailand.
Bayer operates a polycarbonate production facility in Map
Ta Phut in Thailand that supplies base materials for a number
of applications. The company wished to equip a small-lot
compounding line that produces colored thermoplastics
resin with an automation system that was state of the art
and also complying with Bayer’s worldwide technology
standards. The aim was an integrated solution for the automation
of the entire production process – a task that was
completed through close cooperation between Bayer and
Siemens directly on-site in Thailand. The SIMATIC PCS 7
process control system provided the basis.
SIMATIC PCS 7 and the Bayer toolkit control all processes
in the plant. The compounding line is one of the first in the
world to use the latest version 6.0 of PCS 7. SIMOCODE and
SIMOREG (DC Drives), linked to the control system by
PROFIBUS, were used as well. The feeders are also integrated
with the control system via a gateway.
The front end is a graphical user interface that is now being
used in all Bayer plants throughout the world. It is characterized
by a flowchart that displays the entire production
process so that the operating personnel have a complete
overview of the current production steps at all times. New
recipes can be created using a PC in the lab sector and then
simply up- or downloaded to the control system in the form
of Excel tables. After completion of a batch, all the production-related
data are returned for documentation, and can
also be displayed as an Excel table.
The automation concept was implemented jointly with
local partners and uses standard routines developed by
Bayer and Siemens Thailand. The application is a typical
example of a company-wide strategy encountered today
in more and more globally active companies: exploiting
rationalization potential in production through the standardization
of processes and systems. With the company’s
unique combination of a local presence and global knowhow,
Siemens is able to optimally support this strategy.
Best practice example:
RohMax Additives production facility, Germany
RohMax Additives GmbH, a Degussa AG´s Company of the
Specialty Acrylics Group, develops and produces innovative
and customized additives for lubricants. With a wide product
portfolio of roughly 120 products RohMax belongs to the
high-yield companies on the specialty chemicals market.
The production of additive is a complex multi-phase batchoriented
polymerization process – with numerous ingredients,
that have to be selected and batch recipes, that lead
to the highest requirements in the matter of batch planning,
batch control, recipe management and route control. Among
several goals of the production improvement, the plant
operational safety was also important. A further optimization
potential in this plant has been exploited in creating a direct
coupling between the production and business level. The
existing ERP-legacy system SAP, via the Production Planning
Module for process industries (PP-PI interface), is seamlessly
integrated into the management execution level with
SIMATIC IT, thus enabling the tightest synchronization
between production orders and the plant operation, and
avoid any wrong production orders.
Furthermore, the SIMATIC IT MES functions work perfectly
with SIMATIC PCS 7 batch flexible at the batch and control
levels. It provides the required extensive and flexible production
order and material and resource management as
well as the necessary archiving and reporting functions in
an efficient and user-friendly graphic environment.
A higher plant availability was also a decisive factor – with
the high standardization level of using TIA components
throughout the whole plant, the stock of spare parts was
reduced. Maintenance times could also be reduced thanks
to the efficient diagnostic and error identification of the
During and after this project, improvements could also be
reported at several levels of the plant life-cycle. For operators,
processes have been made easier to control and at the
same time, the production has become more flexible. At
the bottom line RohMax can now deliver products with
higher and more stable quality.
Heart of the modernized plant are the SIMATIC PCS 7 process
control system and the innovative Manufacturing Execution
System (MES) based on SIMATIC IT. The openness, use of
standards and the scalability of this solution are securing
ability for quickly and economically adapting the additives
production with high flexibility to changing demand.
