摘　　要：以“小炼油、大乙烯”配置的炼化企业为例,从炼油总流程出发,分析其炼油盈利能力差的主要原因是重油加工路线不优化、催化重整(简称重整)装置和催化裂化装置加工能力偏低、焦化装置加工能力偏高、天然气制氢成本高。提出炼油转型升级的两步走思路,讨论了高掺渣催化裂化工艺在炼油转型升级中的效果与不足。在此基础上,利用炼油化工全流程模型,探讨了建设直馏柴油中压加氢改质装置和连续重整装置的必要性,并对建设溶剂脱沥青装置与固定床重油加氢装置进行了比选,为企业的下一步发展提供思路和方向。Taking the integrated enterprise with the small refining capacity and large ethylene capacity as an example,starting from the overall refining process,the main reasons for poor refining profitability are lack of optimization of heavy oil processing route,low processing capacity of catalytic reforming and catalytic cracking units,high processing capacity of coking unit,and high cost of hydrogen production from natural gas.A two-step approach for oil refining transformation and upgrading is proposed,and the effectiveness and shortcomings of residue catalytic cracking in refinery transformation and upgrading are discussed.On this basis,using the whole process model of refining and ethylene plants,the necessity is discussed to construct a medium pressure hydrogenation and upgrading unit for straight run diesel and a continuous catalytic reforming unit,and a comparison is made between the construction of a solvent deasphalting unit and a fixed bed heavy oil hydrogenation unit,so as to provide ideas and directions for the further development of enterprises.
