Control systems for Turbomachinery and beyond!

For each compressor, natural gas, syngas, ammonia refrigeration, air and CO₂ respectively, a dedicated fault tolerant PLC type controller with purposely built control applications was commissioned. In addition, control for 6 steam turbines for Syngas/Refrigerant/Air/CO2 compressors, Generator and boiler feedwater pump were part of the scope as well. Three of these steam turbines also have extraction control enabled.  The scope of this project was limited only to speed control for the turbines and anti-surge control for the compressors, but was a technical challenge in relation to the tight margins for the extraction control pressure. 

Control-Care is providing engineering and  site services, including field commissioning in 2022, support.  This includes the development, support, and maintenance of the process controls and the instrumented protection functions, with the objective of ensuring a safe, reliable, environmentally sound, optimized, and energy-efficient day to day operation. Also including keeping up to date the related controlled documents: Process Control Narratives (PCN), Instrument Safeguarding Narratives (ISN), and Cause and Effect matrices.
