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 sources of catalytic diesel are complex in diesel hydrogenation unit, and total sulfur content and coppercorrosion of by-product liquefied petroleum gas are unqualified. If desulfurization by desulfurization and stripping unit, polymerizationwould be abnormal in polypropylene unit. After transform, liquefied petroleum gas from diesel hydrogenation unit is desulfurized bya separate alkali desulfurization system and qualified. In addition,polypropylene unit works properly, which can reduce millions ofdollars in economic losses annually.
