烟气co2捕集胺液净化回用技术
, PP. 75-78
Keywords: co2捕集,有机胺,热稳定盐,阴离子交换树脂,胺液回用
Abstract:
针对co2捕集系统有机胺液中热稳定盐的积累进而引起胺液损耗增加、腐蚀严重等问题,提出采用阴离子交换树脂去除胺液中热稳定盐阴离子,采用活性炭吸附去除胺液色度,最后采用大孔树脂进一步净化胺液的组合工艺,并对工艺的影响因素,以及净化胺液的吸收性能进行了测试。结果表明:阴离子交换树脂处理工艺在较高的温度、ph值及含盐量水平的条件下,均可以达到较好的效果,热稳盐去除率可达90%以上;变质有机胺液经过处理后,其co2吸附能力恢复至新鲜胺液的92%,并且溶液颜色恢复至淡黄色透明液体,可满足工业回用要求。
