汽油加氢装置在线优化操作生产国Ⅴ汽油

On-line optimization operation of gasoline hydrogenation unit to produce national standard Ⅴ gasoline

中国石油抚顺石化公司120万t/a汽油选择性加氢装置原是按照生产国Ⅳ标准设计的装置,使用的是满足国Ⅳ汽油标准的GARDES工艺和系列GARDES催化剂。通过在线调整该装置各主要参数,在不停工且不更换催化剂的情况下完成汽油质量调整全过程,成功产出满足国家车用汽油国Ⅴ标准的成品汽油。在线优化操作避免了装置停工换剂和技术改造所带来的经济损失,且装置已平稳运行1年,产品均达到国家最新环保法规要求并顺利出厂。

PetroChina Fushun Petrochemical Company’s 1. 2 million t/a gasoline selective hydrogenation unit was designed originally in accordance with the national standard Ⅳ gasoline,which using the GARDES process and GARDES series of catalysts both meeting the national standard Ⅳ gasoline. By adjusting on-line the main parameters of this unit,the whole process of gasoline quality standard promotion has been achieved without stopping operation and replacing catalysts,and the national V gasoline has been produced successfully. On-line optimization operation can avoid economic losses due to conventional stopping operation,replacing catalysts and technological transformation. And this hydrogenation unit has been running smoothly for a year after on-line optimization,and the products meet China’s latest environmental protection regulations.
