摘要

50万t/a柴油加氢改质异构降凝装置操作运行进入末期，会出现催化剂活性下降、原料适应性差、设备缺陷等问题，对装置长周期运行带来较大影响。介绍了装置开炼末期运行情况，分析了影响长周期运行的因素，并提出解决方案。

Abstract

There are problems such as decreased catalyst activity,poor adaptability to raw materials and equipment defects when a 50 000 t/a diesel hydrogenation upgrading-isodewaxing unit runs at the end of an operational cycle,which have a great impact on long-term operation.This paper introduces the operation status of the unit at the end of the operation cycle,analyzes the factors affecting the long-term operation and proposes solutions.
