摘要: 通过对独山子石化百万吨乙烯装置裂解气压缩机四段出口换热器腐蚀原因的分析,确定造成腐蚀的原因是裂解气凝液水中含酸性物质,对碳钢设备具有腐蚀作用,通过加注缓蚀剂等措施,消除了腐蚀,延长了换热器的运行周期。

Abstract:

In this paper, the causes of the corrosion of the fourth stage outlet heat exchanger of cracking gas compressor in the 1.0 Mt/a ethylene plant at PetroChina Dushanzi Petrochemical Company are analyzed. The reason is that the acid substances in gas condensate water corrode the carbon steel equipment. By taking some measures including adding corrosion inhibitor, the corrosion was eliminated and the operation cycle of the heat exchanger was prolonged.

Key words: interstage heat exchanger of cracking gas compressor, anticorrosion, corrosion inhibitor
