自动反冲洗过滤器是利用固定于其中的圆筒形过滤单元表面收集固体颗粒【1]。它由2个过滤罐并联组成，互为备用。每个过滤罐的过滤面积为26．4 m ，由247个末端为金属箍的过滤单元构成，滤芯采用金属丝烧结的4层滤网。投用初期系统运行状态良好，但随着投运时间的延长出现以下问题：(1)进出口压差上升较快，运行周期缩短，严重时每隔2 min就需切换1次过滤器。

(2)过滤器切换频繁，产生大量污油，装置加工损失率大幅超过控制指标(0．6％)，影响装置的经济效益。(3)产生的污油量超出槽油罐的设计排污能力，导致过滤罐中大量的污油无法及时外排，影响反冲洗效果，造成恶性循环，致使现场环境变差，环保合格率降低。(4)滤芯需经常抽出进行煤油清洗，增加了保运人员的劳动强度。2 原因分析及对策2．1 廪因分析。加氢裂化装置原设计为加工胜利油田的轻质油品，现生产中却使用了大量沙特、伊朗等中东地区所产的含硫或高硫原油。装置所用原料油的黏度变化情况见表1。
