摘要
介绍了现有试剂硫酸的主要生产方法,结合某公司镍冶炼厂制酸装置的实际生产情况,研究形成了2种试剂硫酸生产方案,通过对方案进行比选,最终选用发烟硫酸洗涤吸收法生产试剂硫酸。试验结果表明:以冶炼烟气为原料,采用发烟硫酸洗涤吸收法生产试剂硫酸工艺可行,生产的产品硫酸能够达到分析纯规格。
The main production methods of existing reagent sulphuric acid are introduced.Combined with the actual production situation of the acid making unit in a nickel smelter of a company,two reagent sulphuric acid production schemes are studied and formed.Through the comparison and selection of the schemes,the fuming sulphuric acid washing absorption method is finally selected to produce reagent sulphuric acid.The test result shows that the process of producing reagent sulphuric acid by fuming sulphuric acid washing and absorption with smelting acid flue gas as raw material is feasible,and the product sulphuric acid can reach analytical purity.
