液态烃分离装置扩能改造分析

Analysis on the capacity expansion revamping of the liquefied hydrocarbon separation unit

为扩大液态烃分离装置的处理能力,提高精丙烯产量,对洛阳石化公司液态烃分离装置进行了扩能改造。改造的内容主要包括:采用B型导向浮阀塔板替换原F1型浮阀塔板,脱乙烷塔顶冷凝由内回流改成外冷凝加外回流,扩大丙烯脱水、微量S精制系统等。装置生产能力由原来的6.6万t/a提高到13.0万t/a,工业生产标定结果表明各项技术指标值均优于改造前。

To enlarge the processing capacity eft liquefied hydrocarbon separation unit and improve the output of fine propylene, the capacity expansion revamping of a liquefied hydrocarbon separation unit is conducted in Luoyang Petrochemical Company Ltd.SINOPEC.The transformation items include the followings：the F1 type of valve tray is replaced with B type of directed valve trays,the inner reflux on the top of the deethanizer is revamped to the out cooling and out reflux, the system of propylene dehydration and trace sulfur refinement is enlarged. The processing capacity of hquefied hydrocarbon separation unit is improved to 130 kt/a from 66 kt/a.The industsial production test result shows that all the technical indexes are superior to those of the fomer.
