焦炉煤气正、负压 HPF 脱硫工艺比较

摘要

This paper makes a comparison between positive and negative HPF desulfurization proces-ses with respect to process features and economic benefit as well as process equipment,product,raw material and consumption indexes.The result shows that these two processes are similar in operation cost,but positive HPF desulfurization is more economic with regard to construction cost,therefore, positive desulfurization process is broadly adopted in coking industry.%对正、负压HPF脱硫工艺进行工艺特点和经济比较，并对2种工艺的设备、产品、原材料及消耗指标进行了对比，分析可知，操作运行费用2种工艺相当，而建设费用HPF正压脱硫工艺具有优势，因此，正压脱硫在焦化行业中应用广泛。
