甲醇制烯烃工艺烯烃分离开停工与运行优化

Shutdown and operation optimization of olefin separation in methanol to olefin process

介绍榆林化工烯烃分离装置工艺特点,结合运行经验,阐述烯烃分离正常运行工艺操作优化、开停工优化,降低物耗能耗。同时为后期新建项目提供参考。

This paper introduces the process characteristics of the olefin separation unit in Yulin chemical industry,combined with the operation experience,This paper describes the optimization of the normal operation process,start-up and shut-down of olefin separation to reduce material consumption and energy consumption.At the same time,it provides a reference for the later new projects.
