换热器泄漏的原因分析及解决方案

Analysis of Causes for Leakage of Heat Exchanger and Plans for its Solution

介绍合成氨装置氨回收单元中换热器(10E001)在实际生产中的重要性,重点分析了10E001泄漏的原因,主要是活套法兰密封和换热器与管板之间焊接存在缺陷所致。提供了解决方案,避免因10E001泄漏而造成后系统停车带来的经济损失。

A description is given of the importance of the heat exchanger （ IOE001 ） of the ammo- nia recovery section in the ammonia unit in actual production, The analysis is focussed on the causes for the leakage of IOEO01, which is mainly due to the flaw in the welding seam between the exchanger and the tubesheet as well as the lap joint flange seal, A plan is provided for its solution, so as to avoid the economic loss brought about by the shut-down of the post-system on account of the leakage of IOE001.
