摘要:

在环境保护要求日益严格的背景下,汽油油品升级大势所趋。在中国石化引进Phil-lips石油公司开发的S-Zorb脱硫技术提高油品升级过程中,S-Zorb脱硫再生烟气的处理成了该技术推广应用的瓶颈因素。本文通过调研分析认为,对再生烟气的处理建议优先选择引入硫磺回收装置燃烧炉进行,不推荐引入尾气处理的方式,而且需要从工艺设计的角度全方位地综合考虑,并做出合理的调整。

Abstract:

Upgrading the quality of gasoline product to reduce sulfur content in gasoline is a very important measure for environmental protection. Many years ago, Sinopecintroduced the adsorptive desulphurization technology (SZorb process) from Phillips Petroleum Corporation to im-prove the gasoline product quality, and consequently, SZorb process is becoming popular recently. However, howto deal with S-Zorb flue gas effectively has become the bottleneck technology to the extended application of S- Zorbprocess. By research and analysis, we propose that S-Zorbflue gas should be incinerated in the furnace of sulfur recovery unit, and it is not recommended to be reduced in tail gastreatment unit. A comprehensive process design should betaken into account to make a reasonable selection.
