真空碳酸钾法脱硫工艺问题分析及改造

Analysis for problem in vacuum potash desulfurization process and its improvement

介绍了韶钢焦炉煤气真空碳酸钾脱硫工艺,结合生产实际情况,分析了脱硫效率偏低、脱硫液变质、脱硫废液处理困难等问题,从原料控制、生产操作及工艺等方面,采取了相应的改进措施,稳定和提高了脱硫效率。

This paper introduces the vacuum potassium desulfurization process in Shaoguan Coking Plant.Based on actual production,operating problems are analyzed,such as low desulfurization efficiency,desulfurization liquid deterioration,and hard treatment for the desulfurization liquid,etc..Improvement measures are also taken in aspects of feedstock control,operation and process flow so that the desulfurization efficiency can be stabilized and improved.
