Application of ECT Compressor Control System in Synthetic Ammonia Plant
The operation stability of ammonia refrigeration compressor and synthetic gas compressor(ECT)directly affects the operation effect and product quality of synthetic ammonia plant.The characteristics and functions of ECT unit control system are introduced.The anti-surge control of compressor is realized effectively in the start-up stage by fitting the surge line in the control system.By comparing the data of average daily output and energy consumption of ammonia refrigeration compressor and syngas compressor optimized by the control system,the results show that the system reduces unnecessary energy consumption,improves the level of automatic operation,and has stability and reliability.
