Sulfuric acid production from tail gas
Thread Content
Is the tail gas sulfuric acid production process of the northwest lead and zinc smelting plant very backward? When the plant was built in 1986, the sulfuric acid production process adopted the domestic leading technology adiabatic evaporation dilute acid cooling and purification technology "3+1" secondary conversion process. Does any expert have any detailed information on this?
When smelting flue gas to produce acid, the main smelting requirement is the concentration of sulfur dioxide, and it has nothing to do with whether its smelting technology is backward or not. Judging from the situation you mentioned, the purification aspect is not much different from the current technology, but in terms of transformation, it seems that the "3+1" process is a bit behind. However, in terms of data, the technical and operational requirements are not much different from the now popular "3+2" process. You can download relevant materials from this website.
