滨州石化公司针对其催化裂化汽油烯烃含量超标问题,在其200kt/a催化裂化装置上采用了中国石油大学(北京)开发的“催化裂化汽油辅助提升管改质降烯烃技术”,并进行了技术改造。装置运行后,各项指标均达到或优于改造目标,汽油烯烃体积分数降低到35%以下,降烯烃过程中处理量不变,实现了重油提升管和汽油改质辅助提升管的平稳运行,解决了汽油烯烃含量超标问题。与改造前相比,液化石油气收率和丙烯收率增加,年增效益15.6×104RMB$。
Binzhou Petrochemical Company in its catalytic cracking gasoline olefin content exceeded the standard, in its 200kt / a catalytic cracking unit used by China University of Petroleum (Beijing) developed a “catalytic cracking gasoline auxiliary riser quality olefin reduction technology,” and carried out the technology Transformation. After the operation of the unit, all the indexes reached or exceeded the reformation target, the volume fraction of olefins decreased to less than 35%, the treatment volume remained unchanged in the olefin reduction process, and the smooth operation of the heavy oil riser and the gasoline upgrading auxiliary riser was realized, Solve the petrol olefin content problem. Compared with the pre-retrofit, LPG yield and propene yield increase, the annual benefit of 15.6 × 104RMB $.
