延迟焦化装置含氧尾气线腐蚀分析

Corrosion Analysis of Oxygen-containing Tail Gas Line in Delayed Coking Unit

焦化装置液化气脱硫系统含氧尾气线设计为20#钢材质,在使用中管线腐蚀减薄严重,经分析主要是含氧尾气中的氧气、水与铁发生的吸氧腐蚀。

The oxygen-containing tail gas line of the lique?ed gas desulfurization system of the coking unit is designed as 20#steel material.The corrosion of the pipeline is severely reduced during use.The analysis is mainly the oxygen absorption corrosion of oxygen,water and iron in the oxygen-containing tail gas.
