辛烯醛换热器腐蚀分析与防护

Octenal heat exchanger corrosion Analysis and protection

阐述了辛醇装置缩合系统辛烯醛换热器的腐蚀机理与防护措施,对换热器的形貌观察、成分分析、力学性能测试、材料组织等进行了分析,确定了换热器腐蚀形成的原因。提出了预防腐蚀的措施,收到理想的防腐蚀效果。

This paper expounded the corrosion mechanism and protective measures of octenal heat exchanger in thecondensation system of the Octanol Plant,made analysis to the exchanger＇s morphological observation,componentanalysis,mechanical performance testing and material structure,and determined the cause for heat exchanger corrosion.Measures for corrosion prevention were put forward,and ideal corrosion prevention effect was achieved.
