摘要:

介绍了“浆液进料、富氧焚烧”脱硫废液制酸工艺技术特点及实际应用。该制酸工艺的突出特点是高效、稳定、安全、环保、自动化水平高。现该制酸工艺已在国内多家焦化企业投产使用,运行状况良好,有效解决了国内以HPF、PDS等为催化剂的焦炉煤气氨法湿式催化氧化脱硫工艺存在的低纯硫磺产品滞销、资源浪费以及脱硫废液环境污染技术难题,为实现焦化企业长期可持续发展提供了有力的技术保障。

Abstract:

In this paper,introduction is made for technical features and cases in sulfuric acid making process from desulfurization wastewater,which is characterized with “sulfur slurry feeding” and “combustion with rich oxygen air”.This process has advantages of high efficiency,stable operation,safety,environment\|friendliness and high automation level.The process has been put into operation in large\|scale coking plants in China,which has effectively tackled the problems,such as the unmarketable low purity sulfur,poor utilization of sulfur resource and desulfurization wastewater pollution due to wet catalytic oxidation process with HPF & PDS as catalyst and with ammonia as alkali source.It is proved to be a solution for sustainable development of coking industry in the long run.
