新型催化法脱硫技术在硫酸尾气处理工程上的应用

分析目前硫酸尾气治理现状及常用技术存在的问题,介绍一种新型催化脱硫技术处理硫酸尾气并回收硫资源的基本原理、工艺流程和工程实例。与传统的氨-酸法、活性焦法、石灰石-石膏法对比,新型催化法技术采用低温非钒系催化剂可有效脱除硫酸尾气中的SO2,保证ρ(SO2)<50 mg/m3,达到新标准所规定的限值。该方法处理硫酸尾气具有广阔的应用前景。

Application of new type catalytic method desulfurization technology in sulfuric acid tail gas treatment engineering

Based on the analysis of the present situation of sulfuric acid tail gas treatment and the existing problems of commonly used technology, a new type catalytic desulfurization technology including the basic principle, the process and engineering project for the treatment of sulfuric acid tail gas and recovery sulfur resources is introduced. Compared with the traditional ammonia-acid method, activated char method, limestone-gypsum method, the new type catalytic method uses low temperature non-vanadium catalyst, can effectively remove the SO2 in sulfuric acid tail gas, to ensure p（SO2） 〈 50 mg/m3, meeting the new standards, the technology has broad application prospect in sulfuric acid tail gas treatment.
