石脑油芳烃抽提工艺改造与参数优化

Revamping of atmospheric naphtha aromatics extraction unit and process parameters optimization

大庆联谊石化股份有限公司50kt·a^(-1)芳烃抽提装置以常压石脑油为原料,在开工及生产过程中出现了芳烃混浊发泡、颜色发黄、抽余油芳烃含量不合格等问题,通过技术改造,解决了这些问题,优化了常压石脑油芳烃抽提工艺操作参数,取得了很好的经济效益。

Atmospheric naphtha was taken as the feedstock of 50kt · a^-1 aromatics extraction unit in the Daqing Lianyi Petroleum Chemical Industry Co. Ltd.. Problems such as turbid, bubbling and sallow aromatics occurred during the process of start up and production and the extracted aromatics were umqualified. After revamping, the problems had been solved and appropriate operation parameters were found out. Good economic benefits had been obtained.
