摘要
丹麦托普索湿法制酸(WSA)工艺可以有效地利用各种生产过程中产生的含硫酸性气体直接制酸,得到商品级浓硫酸,具有适用范围广、工艺流程简单、硫回收率高、操作成本低、经济效益好等特点,是石油、石化、冶金、化肥、发电、焦化、煤化工等行业的一种可供选择的有竞争力的硫回收工艺路线。简要介绍WSA工艺的原理、流程、技术特点和应用前景。
The Denmark Topsoe Wet Gas Sulfuric Acid （WSA） process can effectively use sulfur-bearing acid gas generated from various processes to produce acid directly, so as to produce trade grade concentrated sulfuric acid, which is characterized by wide application, simple process, high recovery rate of sulfur, low operation cost and good economic benefit, and is regarded as a competitive sulfur recovery process selectable for petroleum, petrochemical, metallurgy, fertilizer, power generation, coking and coal chemical industries. This paper briefly introduced the principle, process, technical features, and application prospect of WSA process.
