Abstract:

This paper introduces the process flow and feature of sulfuric acid making process with low quality sulfur and desulfurization waste water,and analyzes main parameters such as technical and economical indexes,emission indexes and environment protection indexes.By this process,the problems existed in the recovery of low quality sulfur and in the treatment of by\|product salt solution of desulfurization are fundamentally solved,the efficiency of desulfurization and cyanide removal from COG is effectively improved,discharge of waste is reduced and the environmental protection level is increased.
