重庆天然气净化总厂引进分厂280×104 m3/d 脱硫装置MDEA溶液再生系统溶液循环泵出口压力一直不稳定，极易因泵出口流量骤降导致系统联锁停车。从工艺、设备和管线布置方面进行了分析，发现弯头过多不是导致系统压降高的主要原因，“Π”型管的布置方式可使该处压力降低，酸气发生解析及聚集，进而导致溶液循环泵吸空，引起泵出口压力波动，对系统运行产生较大影响。

Serving as the critical equipment of solution regeneration system in 2 800 × 103 m3/d MDEA desulfurization unit in Yinjin Branch of Chongqing General Natural Gas Purification Plant ,the solution circulation pump has an unstable outlet pressure .The system interlock shut-down due to the sudden drawdown of pump outlet flow rate occurred frequently .The process ,e-quipment and pipeline layout were analyzed ,and the results showed that excessive elbows were not the main reasons of system pressure drop .The layout of Π type pipeline would reduce the pressure and result in the evolution and accumulation of acid gas ,thereby leading to the suction of MDEA circulation pump and the fluctuation of pump outlet pressure ,which would bring great influence to the operation of system .
