摘　　要：介绍了以焦炉煤气氨法湿式催化氧化脱硫产生的低纯硫磺及副盐废液为原料,采用"富氧燃烧、二转二吸"技术制取硫酸的新工艺,以及装置投产后的生产运行情况。This paper introduces a new H2SO4 making technology by adopting ＂ rich oxygen combustion＂ and ＂twice conversion ＆ twice absorption＂ processes in treatment of low purity sulfur and secondary salt waste liquor produced from COG desulfurization by wet catalytic oxidation. Operating conditions after commissioning are also introduced.

关 键 词：煤气脱硫 低纯硫磺 副盐废液 制酸技术
