摘　　要：通过建立炼油PIMS规划模型,对俄罗斯轻质原油的两种加工流程进行了模拟。这两种流程的主要区别在于减压渣油加工方法的不同,一种采用减压渣油加氢流程(流程Ⅰ),主要重油二次加工装置为渣油加氢、蜡油加氢裂化和重油催化裂化;另一种采用减压渣油延迟焦化流程(流程Ⅱ),主要重油二次加工装置为延迟焦化和蜡油加氢裂化。两种加工流程均按10.00 Mt/a加工规模设计,流程Ⅰ包含16套加工装置,流程Ⅱ仅11套加工装置,后者比前者简单。模型运行结果表明,流程Ⅱ投资少,加工成本低,柴汽比高,但要考虑石油焦市场;流程Ⅰ产品多样,产出液化石油气较多。如何选择两种流程,取决于产品的价格体系。Two process options for processing Russian light crude were simulated on the refinery PIMS planning model. The major differences between these two process flow options are in the processes applied for processing vacuum residue （VR）. In VR hydrodesulfurization process scheme （Option Ⅰ ）, the main downstream process units are residue hydrodesulfurization unit, gas oil hydrocracking unit and heavy oil fluid catalytic cracking unit （FCCU）, while in delayed coking process scheme （Option Ⅱ ）, the major process units are delayed coker and gas oil hydrocracking unit. When the two options are designed at a capacity of 10 million ton per year, the Option Ⅰ requires 16 process units while Option Ⅱ needs 11. The results of modeling demonstrate that, Option Ⅱ is low in capital investment and operating cost and high in diesel to gasoline ratio, and the market for petroleum coke needs to be considered, while Option Ⅰ is various in products and high in LPG production. The selection of the process scheme shall be based upon the price system of products.
