硫酸尾气处理技术现状与趋势

摘要

The primary pollutant that discharged by sulphuric acid industry is sulfur dioxide,with ＂sulphuric acid industry standard for discharge of pollutants＂ being promulgated and implemented,the sulfuric acid tail gas discharge limit is asked more and more stricter.The paper produces the theory and feature of sulfuric acid tail gas desulfurization technology,presents that ammonia-acid method is the most widely-used and well-developed way,and analyzes the prospects that desulphurization technology like the carbon method and ionic liquid method will be applied to sulfuric acid tail gas desulphurization.%硫酸工业向大气排放的主要污染物是二氧化硫,随着《硫酸工业污染物排放标准》的颁布与实施,对硫酸尾气的排放限制要求更加严格。本文概述了硫酸尾气脱硫技术的原理及特点。详细介绍了目前技术最成熟、应用最广泛的是氨-酸法,分析了炭法和离子液法等烟气脱硫技术将会应用于硫酸尾气脱硫的前景。
