摘要/Abstract

摘要： 以规划新建12 Mt/a加工沙特中质原油的大型炼油厂为例，采用PIMS线性规划模型，以最大化多产清洁汽油为主要目的，比较了方案1（常压渣油加氢脱硫+重油催化裂化）和方案2（渣油加氢脱硫+重油催化裂化+加氢裂化）两种核心总工艺流程。结果表明，在正常的加工模式下，方案1的汽油产量可达到4.474 4 Mt/a，远高于方案2 的4.051 6 Mt/a。在方案1的基础上，通过催化裂化轻汽油醚化、液化气的烷基化以及副产的苯与催化裂化干气中的稀乙烯合成乙苯等措施进一步增产汽油，可增产汽油组分0.718 Mt/a，同时通过优化汽油池中各调合组分的比例，使混合汽油产品性质满足GB17930—2013清洁汽油产品质量指标要求。

Abstract: The grass-root large-scale refinery with a capacity of 12.0 Mt/a processing Saudi Arab medium crude is studied for maximizing clean gasoline production by PIMS linear programming mode. Two typical refining configurations of Case 1 (the combination of ARDS+RFCC) and Case 2(the combination of RDS+RFCC and VGO HCR) are compared. The results show that the Case 1 with 4.4744 Mt/a gasoline production is better than the Case 2 with 4.0516Mt/a gasoline. Based on Case 1 selected, more gasoline with the production of 0.718 Mt/a can be further increased by FCC light fraction etherification, LPG alkylation and ethylbenzene synthesis of benzene and thin ethylene in RFCC. And clean gasoline product meeting the GB17930—2013 standard can be obtained by optimization of blending ratio of the gasoline pool components.
