浅谈湿式氧化法脱硫装置的设计及管理

Elementary Introduction to Design and Management of Wet Process Oxidative Desulfurization Unit

随着原料煤硫含量不断上升,湿式氧化法脱硫装置出现了堵塔、格栅填料倒塌等现象。通过采用两级脱硫工艺对脱硫装置进行改造,基本解决了脱硫装置在运行过程中出现的问题。针对湿式氧化法脱硫工艺的特点,分析了脱硫装置在设计中应注意的问题,并从脱硫溶液的组分、循环量、温度、再生及回收方面提出了优化工艺管理的措施。

With an ever-increasing sulfur content of feed coal, blocking and collapse of packing in grid appear in the wet-process oxidative desulfurization unit. By revamping with the adoption of twostage desulfurization process for the unit, the problems in the operation of the unit are basically solved. In view of the characteristics of the process, an analysis is made of the main problems in the design of the desulfurization unit, and optimized management measures are proposed with respect to the composition, circulation rate, temperature, regeneration and recovery of the desulfurization solution.
