苯胺冷凝器换热管泄露失效原因分析及对策

Analysis on Leakage Causes of Aniline Condenser Heat Exchanger Tube and Countermeasures

针对苯化工装置冷凝器换热管早期失效的问题展开讨论,提出造成腐蚀穿孔的几种原因,阐述造成腐蚀的原理。结合实际,提出改变结构形状,进行防腐处理,改善循环水质等措施,避免泄漏的发生。

Focusing on the problem of the failure at early period of condenser heat exchanger tube of benzene chemical plant installations, puts forward several causes of corrosion perforation, and expounds the theory of corrosion. Integrating theory with practice puts forward countermeasures, such as changing the structure and shape, using preservative treatment, improving recycled-water, etc. so as to try to avoid leakage.
