硫酸是一种重要的基本化工原料。在我国,硫酸产品有20％、75％、93％和98％等不同规格。硫酸主要用于生产磷肥,其消费量占硫酸的总消费量的60％以上。硫酸还用于生产硫酸铝、硫酸锌、硫酸铜、硫酸镍、硫酸亚铁等硫酸盐产品。此外,硫酸在国民经济各行各业都有广泛的应用。 工业上生产硫酸的方法主要有接触法和硝化法(塔式法)两种。国内目前全部以接触法生产。我国硫酸生产发展速度很快,50年代硫酸年产量仅
Sulfuric acid is an important basic chemical raw material. In our country, sulfuric acid products have different specifications such as 20%, 75%, 93% and 98%. Sulfuric acid is mainly used for the production of phosphate fertilizer, and its consumption accounts for more than 60% of the total consumption of sulfuric acid. Sulfuric acid is also used in the production of sulfate products such as aluminum sulfate, zinc sulfate, copper sulfate, nickel sulfate, and ferrous sulfate. In addition, sulfuric acid is widely used in all walks of life in the national economy. There are two methods for producing sulfuric acid in industry: contact method and nitration method (tower method). At present, all domestically produced by contact method. The development of sulfuric acid production in China is very fast. The annual output of sulfuric acid in the 1950s was only
