Production of acid from smelting flue gas
Thread Content
Our company plans to invest in a copper smelting plant abroad: a blast furnace combined with a PS converter. The blast furnace generates 30,000 m3/h of flue gas with an SO2 concentration of 3–4%, while the converter produces 18,000 m3/h of flue gas with an SO2 concentration of 7–8%. The converter operates intermittently, stopping for 15 minutes every two hours. May I ask what technology would be most cost-effective for this investment, and approximately how much would it cost? It’s okay if the exhaust emissions exceed the limits.
Calculated based on the maximum flue gas volume, it corresponds to acid production from 100,000 tons per year of smelting flue gas, and it is considered a small-scale acid production facility.
