摘要
介绍300kt/a乙苯装置脱丙烯系统于2021年5月4日完成优化改造后投入使用,富丙烯干气外送量由500Nm^(3)/h提高至3500Nm^(3)/h,回收多余的乙烯气体,解决了装置运行过程中存在的问题。
It is introduced that the propylene removal system of 300kt/a ethylbenzene unit will be put into operation after the optimization and transformation is completed on May 4,2021.The delivery volume of propylene rich dry gas will be increased from 500Nm3/h to 3500Nm3/h,and the surplus ethylene gas will be recovered,which solves the problems existing in the operation of the unit.
