磨深1井脱水脱烃装置醇回收工艺优化探讨

磨深1井50×104 m3/d脱水脱烃装置采用注乙二醇抑制剂+外制冷工艺,其醇回收工艺采用刮板薄膜蒸发器法,由于缺乏乙二醇加注量的成熟经验,故为试车难点之一。通过分析醇回收工艺特点、计算乙二醇加注量理论值,并在实际操作和理论计算的基础上探索最佳操作参数,为装置顺利开产提供技术支撑。

Alcohol recovery process optimization of dehydration and dealkylation device of Moshen No.1 Well

The ethylene glycol injection inhibitors and outside refrigeration technology have been used in dehydration and dehydrocarbon device of Moshen No.1 Well with the capacity of 500×103 m3/d.Owing to the lack of experience in the dosage of glycol,the scraper film evaporator used in alcohol recovery process is one of the difficulties in trial run.Based on the theoretical calculation through analyzing the character of the alcohol recovery processes and calculating the theoretical addition amount of ethylene glycol inhibitors,the optimal operating parameters were explored in the actual operation,which would provide technical support for successful production.
