介绍采用DSC脱硫剂对金陵石化公司炼油厂污水汽提装置副产氨气的脱硫工艺以及脱硫剂的再生方法。装置投人工业应用运行一年多来，氨气中H2S降至2mg／m3以下，总硫小于15mg／m3，总硫脱除率达65％～75％，液氮质量明显提高，取得了较高的经济效益。另外，采用DCZ脱色剂，可除去液氨中的酚、铁等杂质，使液氮颜色大为改善。 Desulfurization process using DSC desulfurizer for byproduct ammonia gas from wastewater stripping plant of Jinling Petrochemical Company and the regeneration method of desulfurizer are introduced. More than a year after the plant was put into industrial application, the H2S in ammonia gas dropped below 2mg / m3, the total sulfur was less than 15mg / m3, the total sulfur removal rate reached 65% -75%, and the quality of liquid nitrogen was obviously improved. High economic benefits. In addition, the use of DCZ decolorizing agent, liquid ammonia can be removed phenol, iron and other impurities, so that liquid nitrogen color greatly improved.
