减少乙二醇装置循环气冷凝液系统聚合物生成

Reduction the Polymer Generation of Cycle Gas Condensate System in Glycol Plant

针对环氧乙烷/乙二醇装置循环气洗涤泵入口过滤器频繁堵塞的问题,分析了循环气冷凝液系统固体聚合物的生成机理,聚合物生成对装置生产造成的影响,以及可能减少聚合物生成的因素,并在操作优化上进行实践,操作优化后固体聚合物生成明显减少,对装置平稳生产带来了积极影响。

For ethylene oxide/ethylene glycol plant cycle gas wash pump inlet strainer jams frequent problems,the solid polymer formation mechanism of the cycle gas condensate system,the polymer generation impact to the plant running,and the factors of reducing the polymer generation were analyzed,and operation in the practice was optimized,the solid polymer generation reduced significantly,which brought positive influence to the plant stable running.
