摘　　要：针对真空碳酸钾脱硫工艺出现的问题,采用QC工具进行分析,找出影响煤气出口H_(2)S含量升高的因素。经3过制定对策、检查效果、巩固措施,提高了脱硫效率,降低了煤气出口H_(2)S含量,H_(2)S含量平均值从230 mg/m^(3)降到180 mg/m^(3),达到了预期目标。In response to the problems encountered during the operation of the vacuum potassium carbonate desulfurization process,QC tools were used to analyze and identify the end factors that affect the H_(2)S content at the outlet of the vacuum potassium carbonate desulfurization process.Through formulation of solutions,inspection and consolidation of measures,the desulfurization efficiency was improved and the goal of reducing the H_(2)S content was achieved at outlet of the vacuum potassium carbonate desulfurization process.The average H_(2)S content has decreased from 230 mg/m^(3) to 180 mg/m^(3),meeting the expected target and ensuring stable production.
