摘　　要：中海石油(中国)有限公司湛江分公司东方终端天然气工艺处理过程中需要使用硅胶脱水系统对天然气进行脱水,以满足下游用户供气的水露点标准.在硅胶的再生过程中,高温再生气经过硅胶填料塔后进入MDEA脱碳系统和主天然气工艺一起处理,其携带的液体中含有的轻质油造成MDEA脱碳系统溶液污染,增加了活性炭过滤器的负荷.本文介绍了对再生气流程进行改造,解决了再生气的携液问题从而保障了MDEA脱碳系统的稳定运行.Zhanjiang Branch of CNOOC(China)Co.,Ltd Dongfang terminal's process of natural gas processing,silica gel dehydration system is needed to dehydrate the natural gas to meet the water dew point standard of downstream users.In the regeneration process of silica gel,high temperature regeneration gas enters MDEA decarburization system after passing through silica gel packed tower and is treated together with main natural gas proces.The light oil contained in the kiquid aried by it causes solution pollution of MDEA decarburization system and increases the load of active carbon filter.This paper introduces the revamping of regeneration gas process,which solves the problem of liquid carrying in regeneration gas and ensures the stable operation of MDEA decarbonization system.
