Long-term safety and IT security concepts for greater security
Working with chemical substances requires the highest safety standards. health, Safety & Environment (HSE) regulations must be strictly adhered to. The goal of our safety solutions is to guarantee process and plant safety throughout the entire lifecycle – for example, through ex protection, functional safety, defense-in-depth concepts and risk management. Our focus is directed at plant security through access protection, technical measures related to hard-ware and software, and to the protection of plant-wide communication and networks. Availability analyses and redundancy concepts ensure plant reliability. We achieve high-level system integrity through service concepts that, among other things, enable transparent data management. All of these factors represent opportunities for increased production through suit-able safety measures.
In the chemical industry, large quantities of oxygen and nitrogen are required for processing input and intermediate products. They are obtained in automated air separation plants. The most important operational goals are to minimize production costs by reducing energy consumption and to ensure product quality. Energy supply and compression play a key role in the separation process. Compressors suck in the filtered air and compress it to the necessary pressure before it is cooled and separated into its main components. Compressor units then compress oxygen and nitrogen so that they can be fed into a pipeline network for further use. Our many years of experience in this field make us a strong partner. We offer innovative solutions for numerous air compression applications – precisely tailored to your specific needs.
Condition monitoring: process control and analytical devices
Energy and maintenance costs make up a large part of production costs. Precise monitoring is needed for cost optimization and control. This requires continuous and reliable process gas analyses. Comprehensive diagnostics functions are also essential prerequisites for condition monitoring and asset performance management. For monitoring and analyzing mechanical assets such as pumps, valves and heat exchangers, we use package units and also mobile apps as an integral part of the process control system.
Process analysis with cryogenic air separation
Cryogenic air separation (aka high-pressure Linde-Frankl process) is a powerful and economical process used for the production of oxygen and nitrogen. Monitoring and optimizing processes requires process analyzers, which deliver essential data from various plant areas on energy consumption and the control of product quality. These are crucial objectives for lowering production costs.
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.
Process instrumentation and analytics
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.
Monitoring and control devices
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.
Energy-efficient switchgear technology
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.
