摘要
介绍中国石油兰州石化分公司石油化工厂105kt/a芳烃抽提装置的汽油加氢扩能改造目的、内容和效果。改造后处理加氢汽油的能力由原来的9.5t/h提高到了13.5t/h,日增产三苯62t。装置运行平稳,苯的纯度不小于99%,甲苯的纯度不小于98%,混合二甲苯的纯度下小于85%。设备投资小,经济效益明显,顸计年增经济效益3069万元。
The technological remoulding of aromatics extraction unit in Lanzhou Petrochemical Company was introduced. The capacity of treating hydrogenated gasoline increased from 9.5 t/h to 13. 5 t/h after the remoulding and good benefit was obtained.
