摘　　要：柴油加氢装置催化柴油原料来源复杂,副产品液化气总硫含量和铜片腐蚀不合格,如果经脱硫脱硫醇装置脱硫后,将会造成下游聚丙烯装置聚合反应异常。改造后,采用碱液脱硫系统单独脱除柴油加氢液化气硫化物,处理后液化气质量合格。聚丙烯装置生产正常,每年可减少上千万元的经济损失。The material of catalytic diesel are complex in diesel hydrogenation unit,which has led to substandard of total sulfur content and copper corrosion of by-product liquefied petroleum gas(LPG). Furthermore,LPG desulfurized by desulfurization and stripping unit will cause abnormal polymerization in downstream polypropylene unit. LPG from diesel hydrogenation unit is desulfurized by a separate alkali desulfurization system and qualified after revamp. The polypropylene unit is in smooth operation,which can reduce losses of millions Yuan annually.
