炼厂干气预处理技术与研究

PRETREATING TECHNOLOGYAND RESEARCH FOR REFINERY TAIL GAS

介绍并比较了几种预处理方法，对选择性脱除有机硫和等温—绝热法加氢进行了试验，将等温—绝热法加氢工艺实现了工业化。使含有机硫３００～１０００ｍｇ／Ｌ，烯烃１０％～２０％的炼厂干气经净化处理后，硫含量小于０．５ｍｇ／Ｌ，烯烃含量小于０．５％。

Some pretreating methods are presented and compared in this articleTests were made for the selective removal of organic sulfur and isothermaladiabatic hydrogenatingAnd the process of isothermaladiabatic hydrogenating has been put into industrial productionThe feed gas contained organic sulfur 300～1000mg/L,olefine 10%～20%After purification treatment,sulfur content was reduced to less than 05mg/L and olefine less than 05%
