摘　　要：某炼油厂设计规模为0.8 Mt a丁烷溶剂脱沥青装置,采用UOP公司DEMEX工艺技术,以减压渣油为原料,丁烷为溶剂,自2002年首次开工以来,装置运行稳定,产品质量、装置能耗以及运行参数符合设计要求和控制要求。但随着减压渣油不断重质劣质化,装置运行出现脱沥青油收率低、抗车辙母粒软化点低等问题。基于此,分析了装置运行出现问题的原因,提出了解决方案和优化措施,为装置的安全平稳运行提供了新思路。This article introduces the scale of 0.8 Mt a butane solvent deasphalt unit of a refinery,using UOP DEMEX process technology,vacuum residue as raw material,butane as solvent,since the first start of 2002 the unit has been stable operation,product quality,device energy consumption and operating parameters meet the design requirements and control requirements.However,as the vacuum residue continues to become heavy and inferior,problems such as low yield of deasphalting oil and low softening point of rut-resistant masterbatch appear in the operation of the device.In view of the problems in the long period operation of the solvent deasphalt unit,optimization and adjustment measures are taken,and suggestions are put forward in combination with the problems existing in the overall operation of the device,providing new ideas for the safe and stable operation of the unit.
