中海油东方石化一期液化气脱硫醇装置配置2台碱液精细过滤器,正常工况下一台运行,一台备用。本装置于2014年1月开工,整体运行情况平稳,产品液化气总硫指标能够控制在设计指标范围之内,但也存在碱液精细过滤器易堵塞,更换精细过滤器内芯和更换全部碱液以后,对过滤器吹扫依旧频繁,增加了劳动强度,同时影响了碱液循环量,造成装置操作不平稳。本文针对碱液精细过滤器运行过程中存在的问题进行分析,并提出解决办法。 CNOOC Dongfang Petrochemical Phase I liquefied gas desulfurization unit equipped with two lye fine filter, under normal operating conditions, a spare. The unit started in January 2014, the overall operation is stable, the product of liquefied petroleum gas total sulfur index can be controlled within the scope of the design specifications, but there are also easy to lye fine filter plug, replace the fine filter core and replace all the base After the liquid, the filter is still frequent purges, increasing labor intensity, while affecting the amount of lye circulation, resulting in unsteady operation of the device. This paper analyzes the problems existing in the operation of lye fine filter and puts forward the solution.
