摘　　要：介绍了中国石化河南油田分公司南阳石蜡精细化工厂采用中国石化石油化工科学研究院开发的轻汽油碱抽提(SCE)工艺建成的轻汽油脱硫装置一年多来的运行情况。结果表明:装置轻汽油脱硫醇率近100%,保证了满足国Ⅳ排放标准汽油产品的稳定生产;碱液经再生与反抽提处理后,几乎不再含有硫醇钠盐与二硫化物,碱液获得了长期有效的利用,实现了零碱渣排放。Light FFC naphtha （LCN） caustic extraction technology developed by SINOPEC Research Institute of Petroleum Processing was adopted in Nanyang Wax Fine Chemical Factory of Henan Oil- field. The results of operation more than one year show that the removal of mercaptan from LCN is nearly 100%. The production is stable and the product can meet the requirement of the national emis- sion standard phase VI on gasoline pecification. After regeneration and reverse extraction process, the caustic liquor almost no longer contains mercaptan sodium and disulfide, thus long-term effective use of caustic liquor could be realized with zero discharge of caustic liquor residue.
