摘　　要：本文通过对我国焦化厂常用的湿式氧化法,真空碳酸钾,低温甲醇洗和NHD脱硫等几种焦炉煤气脱硫工艺的特点及应用进行分析研究,以年产130万吨焦化厂焦炉煤气脱硫为例,在操作条件、设备投资、脱硫效果、运行费用等方面进行对比,从电耗、蒸汽能耗、脱硫剂消耗三个方面进行经济性分析,以期为焦化厂选用焦炉煤气脱硫工艺提供参考和帮助。Through the analysis and study of the coke oven gas desulfurization process commonly used in existing coking plants, this paper introduces the research progress of several coke oven gas desulfurization processes such as wet oxidation method, vacuum carbonate desulfurization, low temperature methanol absorption method and NHD method, taking the annual output of 1.3 million tons of coke oven gas desulfurization as an example, comparing the operating conditions,equipment investment, desulfurization effect, operating costs, etc., and conducting economic analysis from three aspects: electricity consumption, steam energy consumption and desulfurizer consumption. In order to provide reference and assistance for the coking plant to select the coke oven gas desulfurization process.
