利用现有装置增产汽油的方案探讨

摘要

根据中国石油大港石化公司现有装置结构,通过拓宽汽油馏程、增产重整原料、优化催化裂化原料及负荷等方案的实施,达到降低柴汽比、提高汽油产量的目的.实践证明:在装置结构不变的情况下,通过生产优化可以在一定程度上改变目的产品收率,实现效益最大化.通过以上调整,效果非常明显,可增产汽油315 t/d,柴汽比从2.43降低到1.60,效益增加21.9万元/d.%The solutions of maximizing gasoline using the existing units in Dagang Petrochemical Company were discussed.The main methods,such as broadening gasoline distillation range,increasing reforming unit feedstock,optimizing FCC raw materials and load,were taken to low diesel/gasoline ratio and raise yield of gasoline.The practices prove that in existing units,through production optimization,gasoline increases by 306 t/d and diesel/gasoline ratio drops from 2.43 to 1.60,while the benefit increases 21.9 × 104 Yuan/d.
