摘　　要：针对某石化公司1.0 Mt/a连续催化重整装置苯产品白土预处理工艺精制深度不够、重组分产量大、白土失活快以及二甲苯加氢系统工艺流程较复杂、能耗大等问题,采用中国石化长岭分公司和湖南长岭石化科技开发有限公司共同开发的重整生成油管式反应器液相加氢工艺(简称FITS工艺)对重整生成油进行脱烯烃处理。该工艺利用氢气纳米级微孔分散技术,使氢气在油相中均匀分散,能有效脱除重整生成油中的烯烃,满足苯产品溴指数小于20 mgBr/(100 g)、混合二甲苯产品溴指数小于50 mgBr/(100 g)的控制要求。FITS工艺的成功投用,可以停用精制苯的白土罐、二甲苯的加氢单元,大幅降低了芳烃处理单元的能耗和运行成本。In response to the problems of insufficient refining depth,high yield of heavy component,fast deactivation of clay,and complex process and high energy consumption of xylene hydrogenation system in a 1.0 Mt a continuous catalytic reforming unit of a petrochemical company,the reformate was treated with the liquid phase hydrogenation process(FITS process)developed by SINOPEC Changling Company and Hunan Changling Petrochemical Technology Development Co.,Ltd..The process makes use of hydrogen nano-pore dispersion technology to make hydrogen evenly dispersed in the oil phase,and can effectively remove olefins from reformate.The bromine index of benzene product is less than 20 mgBr(100 g),and that of mixed xylene product is less than 50 mgBr(100 g).The successful application of FITS process could eliminate clay tank for benzene refining and xylene hydrogenation unit,and greatly reduce the energy consumption and operating costs of aromatics treatment unit.
