扫码查看
溶剂再生单元是渣油加氢装置及下游装置脱硫系统的关键装置.针对某公司渣油加氢装置溶剂再生塔异常波动的情况,采取了再生塔回流罐顶增设除盐水线、调整再生塔操作参数、添加部分新鲜胺液及采用高精密滤芯过滤器技术净化胺液等措施后,该溶剂再生单元逐渐恢复平稳,贫胺液下游装置产品质量合格,加热炉尾气SO2排放恢复至控制指标内,达到环保要求.
Abnormal Fluctuation Analysis and Countermeasures of Solvent Regeneration Tower
The causes of abnormal fluctuation of solvent regeneration tower in residue hydrotreating unit were analyzed,and the optimization and adjustment measures were introduced,including adding demineralized water line on the top of the reflux drum of the regeneration tower,and adjusting operation parameters of regeneration tower,adding some fresh amine liquid and purifying amine liquid by using high precision filter technology.Finally,the product quality of the downstream device of the lean amine solution was qualified,and the SO2 emission of the tail gas of the heating furnace met the environmental protection requirements.
