In the production of sulfuric acid as a by-product, basic metal smelting unit, oil refineries and coal-fired power plants are required to reduce sulfur gas emissions during industrial processes in order to control pollution
The main method of commercial production of Sulfuric acid is that sulfur dioxide is first prepared from sulfur. Sulfur dioxide is then converted to sulfur trioxide in the process of catalytic oxidation, and then concentrated sulfuric acid is produced by the sulfur trioxide reaction with water.
Sulfuric acid production is done in two general ways: main product (optional production) or by-product (forced production). In the production of sulfuric acid as the main product of a production unit, methods such as sulfur combustion(or sulfur-burning), pyrite Roasting and sulfuric acid recycling have been used.
In the production of sulfuric acid as a by-product, basic Metal smelting unit, oil refineries and coal-fired power plants are required to reduce sulfur gas emissions during industrial processes in order to control pollution.
Therefore, this type of sulfuric acid production is known as forced production. In basic metal smelting units, sulfur dioxide gas (SO2) is produced during the process of smelting or roasting sulfide concentrates of Metals such as copper, Zinc and lead. Melting units mainly convert output sulfur-containing gas from the melting furnaces into sulfuric acid.
