摘要
介绍了废硫酸制备石膏的生产工艺:通过对乙炔清净废硫酸进行处理,然后再与电石渣浆中和,最后制成石膏。采用该石膏可以生产出合格的水泥。
A production process of preparing gypsum from waste sulfuric acid was introduced. The waste sulfuric acid formed in acetylene purification was treated, neutralized with calcium carbide slurry, finally gypsum was produced. Qualified cement could be produced from the gypsum.
