摘要
通过对中石油独山子石化分公司乙烯厂乙二醇(6万吨EO/EG)装置的干燥塔釜液泵P-610A/B结焦周期短、检修频次高的原因进行分析并提出改进措施,延长结焦周期、降低检修维护的成本和频次。
The cause of coking,short coking cycle and high frequency maintenance for drying column bottom pump P-610A/B of Ethylene Glycol plant（EO/EG） was analyzed,and some measures were proposed to extending the coking cycle,reducing maintenance cost and frequency for improvement.
