Jinfeng Xifenghang Compression Workshop Continues to Innovate. Author/Source: Jinfeng Xifenghang. Date: 2022-05-08. Clicks: 8. All employees in the compression workshop at Jinfeng Xifenghang are working together to implement measures aimed at reducing costs and increasing efficiency. They identify the causes of issues related to electricity consumption, fuel usage, and the cost per ton of ammonia, seek out areas for improvement, and develop practical solutions, so that everyone is aligned both in thought and action. It is reported that “reducing waste and making use of all available resources” is the guiding principle for cutting costs and increasing efficiency in workshops. The compression workshop is the heart of the ammonia synthesis production system and is also a major consumer of electricity. Building on existing energy-saving measures, this workshop has explored new approaches and put forward innovative plans for process technology upgrades. In summer, the temperature in air separation production systems rises. To ensure that the temperature of the gas exiting the air cooling towers meets the required standards, the load on the chiller units increases continuously. At high temperatures, high-pressure alarms often occur in these units, which undoubtedly reduces their service life and increases power consumption. Sometimes, it is even necessary to reduce the system’s capacity and increase the flow of nitrogen used for pre-cooling in order to lower the temperature of the gas exiting the air cooling towers. Meanwhile, the cooling capacity of the main coolant from the air separation unit as well as that of the non-condensable gases is discharged directly into the atmosphere without being utilized. Therefore, this workshop proposed a new solution: to recover the cooling capacity of the main coolant and non-condensable gases by using heat exchangers made of suitable materials to cool the temperature of the air exiting the air compressors and the temperature of the compressor oil, thereby reducing the load on the chiller units. Upon implementation, as demonstrated, this solution ensures the stable operation of the system while reducing equipment damage and maintenance costs caused by excessive load on the chiller units, thereby achieving efficient operation of the equipment and high productivity with low consumption.
