连续重整装置进料换热器冷侧压降升高的原因分析

Cause analysis of cold side pressure drop rising of reformer feed heat exchanger in continuous catalytic reforming unit

哈尔滨石化公司的连续重整装置重整进料换热器出现压降升高的现象,导致循环氢流量大幅度下降,使装置运行出现困难。文中结合装置的介质特性分析了出现该故障的原因,采取了相应的处理措施,收到理想的效果。

The pressure drop rising phenomenon occurred in the reformer feed heat exchanger of the continuous reforming unit,which caused the recycle hydrogen flow remarkably decreased and made the unit operation difficult.Combined with the characteristics of the medium of the unit,this paper analyzed the causes for the occurrence of this fault,adopted corresponding treatment measures,obtained ideal effect.
