摘要: 某乙烯装置裂解气压缩机在运行过程中出现实际转速无法达到设定值、段间压差呈上涨情况,针对上述情况分析原因,通过采取调整压缩机各段吸入负荷,在压缩机段间冷却器(EH-3302/3303)工艺侧入口进料管道增加洗油注入点注洗油等手段,延长了压缩机运行周期。

Abstract:

During the operation of cracking gas compressor in an ethylene plant, the actual speed cannot reach the set value and the pressure difference between sections is rising. The causes of the problems are analyzed, and the operation cycle of the compressor are prolonged by adjusting the suction load of each section of compressor and adding wash oil injection points at the inlet feed pipe on process side of compressor inter-section cooler for wash oil injection.
