Fully optimizing secondary and auxiliary processes

Process analyzers are essential components in air separation plants. They control and optimize process sequences and ensure product quality. OXYMAT 64 was specially developed for detecting low levels of oxygen in pure gases.

The portfolio fully meets the high demands of the chemical industry (SIL 2/3). Thanks to comprehensive diagnostic functions, you always know when processes are running according to plan, or when corrective action needs to be taken.

It also lets you lay the foundation for condition monitoring and asset performance management. For example, you can check the functioning of the emergency shutdown valves during operation using the partial stroke test.

When it comes to motors, smooth operation and maximum availability are a top priority. Our SIMOCODE pro motor management and control devices as well as our compact SIRIUS monitoring relays offer a high degree of monitoring reliability – from the motor feeders to the automation level.

Electric drives are the biggest industry-related energy consumers, accounting for approximately 70% of the overall electric power demand. Leverage the full savings potential of your electric drive systems and increase your energy efficiency over the long term. Our industrial switchgear technology is here to support you.

We can support you in optimizing your energy utilization and consumption, and can advise you on how to maximize the efficiency of your operations. At the plant level, SIMATIC powerrate for the SIMATIC PCS 7 process control system offers a convincing performance. The software records all of the plant’s energy-related consumption data, assigns the data to the consumer, visualizes it clearly, and saves it in the archive. In this way, it helps you to reliably detect hidden savings potential for targeted energy consumption optimization.

Apart from the components directly related to the engineering process, many production plants have additional machines and aggregates that also need to be controlled. In many cases, these package units are complete subsystem models for specific production tasks. Some are equipped with plant components that are not part of the standard SIMATIC PCS 7 system. New function blocks make it easy to integrate auxiliary plants – for example, for air separation.

In complex chemical plants, powerful compressor solutions are needed that are suitable for a wide range of process requirements – for example, when terephthalic acid (PTA), synthetic fibers, acetate, acrylic acid, PVC/VCM, or nitric acid is used. You can increase your plant’s efficiency with state-of-the-art technologies and tried-and-tested compressor units.

Our steam turbines for power plants are applied either as a generator drive or as a mechanical drive for pumps and compressors. The modular design concept of all steam turbines ensures high flexibility and availability as well as reduced time-to-market

Our field devices reliably deliver ultra-precise measurement data to ensure transparent processes, reproducible batches, and the flexibility required in the industry.

A variable speed drive unit with frequency converters ensures precise and flexible processes, reduces plant component wear and tear, and saves energy. As cabinet units or installation equipment, Siemens frequency converters cover the power range from 0.12 kW to 120 MW and can be integrated into the automation system via PROFIBUS.

Flender gear units and couplings round off our product and system portfolio for a variety of applications ranging from agitators to fans and water spiral pumps. They offer an ecological and technically advanced solution in combination with the ARPEX and N-EUPEX couplings, which have proven to be particularly suitable for conveying and pumping aggressive and hot media.

Whether standard industrial motors, motors with corrosion-proof and chemically resistant coatings, explosion-proof EEx motors, highly efficient energy-saving motors, NEMA motors for the North American market, or Loher CHEMSTAR motors with complete documentation and ATEX certificates – all of our motors and geared motors are manufactured in accordance with the highest quality standards and are certified in accordance with the most important standards and country-specific guidelines. They cover the complete power range from 0.12 kW to 100 MW.

Whether for use in electrical cabinets or in the field with a high degree of protection: Our SIRIUS modular system for industrial control cabinets offers a broad spectrum of communication-capable motor starters and simple load feeders for starting motors.

Electric drives are industry‘s biggest energy consumers, accounting for approximately 70% of the overall electric energy demand. Our SIRIUS modular system for industrial switchgear technology offers a wide range of products enabling you to leverage the full savings potential of your electric drive systems – and increase your energy efficiency over the long term.

With the right drive concept and a customized solution, you can save valuable resources when planning and operating your continuous-flow machines – and benefit from the maximum availability and service life of your systems. We provide targeted support and advice in developing an optimal design and implementing future-proof concepts.

Our portfolio also comprises explosion-protected and safety-oriented process instruments with integrated fail-safe functions. We thus provide you with the answer to increasingly stringent safety regulations and legal provisions, meeting all of the requirements for maximum availability and explosion protection.

The probability of a safety incident and its repercussions can be substantially reduced by applying appropriate protective measures like a Safety Instrumented System (SIS). Safety Integrated is an integrated safety system in which safety functions can be added to standard components of automation and drive systems.  This includes a complete, end-to-end safety system comprising a controller, engineering with the “Safety Matrix” safety lifecycle tool, and safe process instruments. The ability to integrate the SIS into our SIMATIC PCS 7 process control system is unique. Safety sensors can be connected using the PROFIBUS PA fieldbus or the Foundation Fieldbus.

Regular function tests of the emergency shut-off valves can be performed using the Partial Stroke Test with the SIPART PS2 positioner. This can be used to test the movement of the valve by partially opening and closing it during live operation.

All of these actions are not only relevant from a safety perspective but also contribute substantially to the performance of the plant as a whole.
