| titleOfInvention | Process and system for preparing sulfuric acid by using smelting flue gas |
| abstract | The invention relates to a process and a system for preparing sulfuric acid by using smelting flue gas. The process uses sulfur dioxide-containing flue gas of a smelting plant as a raw material, converts sulfur dioxide into sulfur trioxide after purification, deep cooling impurity removal and drying, and then prepares refined sulfuric acid by an absorption method after filtering and washing the flue gas. The invention can maximize the yield of the refined sulfuric acid produced by the sulfur dioxide-containing flue gas of a smelting plant. Meanwhile, the invention enriches the sulfuric acid products of the smelting plant, can flexibly adjust the specification and the quality of the product sulfuric acid to meet the market demand, improves the economic benefit of enterprises, and is suitable for the reconstruction of newly built sulfuric acid devices and old sulfuric acid devices. |
