摘要
丹麦托普索WSA湿法制酸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、煤化工等行业可供选择的、有竞争力的硫回收工艺路线之一。简要介绍了WSA湿法制酸方法的原理及其工艺流程、技术特点和应用前景。
The WSA wet-process acid production process of TopsФe of Denmark may utilize effectivel sulfur-containing acid gases from various production technologies to manufacture acid directly, the commercial-grade concentrated sulfuric acid obtained has the characteristics of large scope of application, simple process flowsheet, high sulfur recovery, low operation cost, and good economic benefit, and it is a competitive sulfur recovery route available to the petroleum, petrochemical, metallurgical, chemical fertilizer, power, coking and coal chemicals industries. A brief introduction is given to the principle, process flowsheet, technical features and use prospect of the WSA wet-process acid production method.
