中国石化济南分公司国Ⅳ、国Ⅴ汽油质量升级过程浅析

Study on Upgrading Gasoline to National Ⅳ&Ⅴ Standards in Jinan Company

介绍了欧盟及我国汽油标准的升级演变历程、常用催化裂化汽油脱硫技术以及中国石化济南分公司汽油调合组分和成品汽油质量现状,阐述了在此背景下济南分公司为实现汽油国Ⅳ、国Ⅴ质量升级采取的多项措施,包括S-Zorb消缺及扩能改造、新建60万t/a逆流移动床催化重整装置、140万t/a重油催化裂化装置稳定塔改造以及MTBE脱硫改造等,最后建议增加芳烃含量低的高辛烷值组分(如烷基化油)生产能力,以满足未来汽油质量升级需要。

Based on analysis of the evolution of domestic and foreign gasoline standards, widely-used FCC gasoline desulfurization technologies, and current gasoline blending components and gasoline product quality in Sinopec Jinan Petrochemical Company, this paper introduces the measures used by the company to upgrade gasoline quality up to nationalⅣ&Ⅴstandards, including expansion of S-Zorb capacity, addition of 60 kt/a countercurrent moving-bed catalytic reformer and revamp of the stabilizer in 140 kt/a FCC unit and the MTBE desulfurization. Finally it suggests that capacity of high quality blending components (e.g., alkylate) with high octane, low sulfur and low aromatics should be added for gasoline quality upgrading in the future.
