GARDES技术在大庆石化130万吨/年汽油加氢改质装置的工业应用

摘要

中国石油天然气集团公司为应对汽油质量升级，首批采用具有自主知识产权的GARDES技术新建7套汽油加氢改质装置，大庆石化为其中规模最大的一套。本文介绍了采用GARDES技术设计建设的大庆石化130万吨/年汽油加氢改质装置的催化剂预处理、装置开工及初期运行情况。2013年10月装置正式开工运行，开工后装置一直平稳运行，11月29日分别在85%、100%负荷两种方案下完成装置初期标定；初期运行及标定结果表明，在85%负荷和全负荷状态下，通过GARDES工艺技术，汽油产品硫含量均能达到30µg/g以下、硫醇硫含量能够控制在10µg/g以下，RON损失为0.2～0.4个单位。GARDES技术可根据实际生产需求灵活调整负荷，催化剂具有优异的加氢脱硫及脱硫醇性能，同时具有较低的 RON 损失，完全满足催化汽油加氢改质装置生产国 IV标准清洁汽油需求，解决了企业汽油质量升级的重大问题。%The proprietary GARDES technology was applied in seven sets of newly-built FCC gasoline hydrogenation unit by PetroChina for gasoline upgrading. The unit at Daqing Petrochemical is the biggest. Industrial application of the GARDES technology in 1.3Mt/year FCC gasoline hydrogenation unit of Daqing Petrochemical is presented. Pretreatment of catalyst and start and operation of the unit are introduced. The unit started operation in October,2013 and operated smoothly. Initial calibration was completed under both 85% loading and 100% loading in November,2013. Sulfur content was below 30µg/g,mercaptan content was below 10µg/g,and loss of RON was between 0.2 and 0.4. Loading could be adjusted flexibly by the GARDES technology. Catalyst matching with the GARDES technology showed excellent performance of hydrodesulfurization and removal of mercaptan along with extremely loss of RON. National IV Standard of FCC gasoline was satisfied by the GARDES technology and catalyst. Gasoline upgrading problem was well resolved by applying the GARDES technology in Daqing Petrochemical.
