FD2G轻汽油脱苯方案研究与应用

STUDY AND APPLICATION OF BENZENE RE-MOVAL FROM FD2G LIGHT GASOLINE

催化柴油加氢转化装置产生的轻石脑油组分轻,异构烷烃和芳烃含量高,特别是苯含量高,不适宜作汽油调和组分和分公司的重整料,作为乙烯料出售效益损失大。通过分析轻石脑油的成分,结合现有可利旧设备、利用RSIM软件进行模拟测算,选定了轻石脑油的最佳脱苯分离方案并实施,实现增产发泡剂或生产优质汽油调和组分,取得了较好的经济效益。

The light naphtha produced in the catalytic diesel hydro-conversion unit has light composition,high content of isomers and aromatics,especially high content of benzene,so it is not suitable to be used as gasoline blending component and reforming material of Branch Company.There is a large loss of benefit from selling it as ethylene material.By analyzing the composition of light naphtha and combining with the available old equipment and simulating calculation with RSIM software,the optimum scheme of removing benzene from light naphtha was selected and implemented to increase the production of foaming agent or production of high-quality gasoline blend components,and better economic benefits were obtained.
