摘要
本文介绍了国内主要硫酸企业应对《硫酸工业污染物排放标准》要求,进行达标治理情况,对硫酸尾气达标治理技术及相关产业进展进行分析,重点探讨了各种硫酸尾气吸收工艺的发展应用优势。建议硫酸企业切合自身实际积极寻求尾气脱硫资源化利用途径,指出系统催化性能改良+简单尾吸工艺是现有冶炼烟气制酸企业尾气治理的最佳选择。
this paper introduced the main technologies used by most Chinese sulfuric acid factories to treat the exhaust in response to the Emission Standard of Pollutants for Sulfuric Acid Industry . It detailed in the comparative analysis for each sulfuric acid exhaust absorption technology , and recommended the factories should actively explore the channel utilizing waste, the desulfured exhaust as a resource. Finally it concluded that the combination of improvement of performance of eatalytic system and the simple exhaust absorption was the best way in exhaust treatment for existing sulfuric acid plants that make acid by using melting off-gas.
