In a pyrometallurgical process, gas from the gas-cleaning section enters the sulfuric acid plant via a drying tower, where most of the humidity is removed to minimize the potential for corrosion inside the plant. Before entering the stainless steel converter, the gas temperature must be increased to accommodate the operating temperature of the catalyst. Sulfur dioxide is converted into sulfur trioxide, and the process gas is sent to the first absorption step where the sulfur trioxide is removed and sulfuric acid is formed. After further conversion, the gas is routed to the stack via the final absorber.
