摘　　要：由于乙烯装置汽油分馏塔(DA101)发生上部填料堵塞,裂解汽油干点升高,重质组分随工艺过程带到分离系统,导致丙烯产品中轻组分超标、碳四产品中碳三超标,碳五产品中碳四含量高、碳九碳十产品颜色加深等一系列的工艺和质量问题。为保证装置安全平稳运行到预定检修日期,采取了一系列措施来保证装置安全生产。Packing blockage in the upper part of gasoline fractionator( DA101) in ethylene plant led to higher final boiling point of pyrolysis gasoline,and heavy components were entrained to the separation system, resulting in a series of process and quality problems including the over high light components in propylene product,the over high C_3 in C_4 product,the over high C_4 in C_5 product and the darker color of C_9 and C_(10) products. A series of measures were taken to ensure the safe and stable operation of the plant until the scheduled overhaul.
