摘要
介绍了中国石化镇海炼油化工股份有限公司柴油加氢装置扩能改造为处理焦化汽油、非芳石脑油的石脑油混合加氢装置后的运行情况、存在的一些问题及解决措施。运行结果表明:在高压分离器压力3.40MPa、第一反应器温度222℃、第二反应器温度266-267℃、体积空速1.85h。的条件下,精制石脑油产品硫质量分数小于200μg/g,能满足乙烯装置石脑油原料的要求和大负荷生产的实际需求;装置总体改造效果较好,反应、分馏及脱硫系统均能保持平稳运行;对于影响装置平稳运行和产品质量的一些问题,经过装置消缺和操作调整后,基本得到解决。
The operation of diesel hydrogenation unit expansion revamping for hydroprocessing the aixed feed of coker gasoline (naphtha) and non-aromatic naphtha were introduced. Problems during the ,peration and measures were discussed and proposed. The practices indicate that at the conditions of Ligh separator pressure 3. 40 MPa, reaction temperature of R1/R2 222 ℃/266--267 ℃ ,LHSV 1.85 h-1 , he sulfur content in the refined naphtha is less than 200 μg/g, meeting the requirements for ethylene ,roduction and large load production as well. All transformation reaction, fractionation and desulfuriza- ion system can keep running smoothly. Some of the issues affecting the smooth operation of the device nd product quality, after eliminating defects and operational adjustment, are basically resolved.
