How to recover flue gas sulfur most economically
Thread Content
Our factory plans to invest in two smelting furnaces: Furnace 1 has a flue gas flow rate of 36,000 m3/h with an SO2 concentration of 20 g/m3, while Furnace 2 has a flue gas flow rate of 10,000 m3/h with an SO2 concentration of 110 g/m3. (This furnace operates intermittently, stopping for 15 minutes every two hours.) I would like to ask everyone how it is most reasonable to recover these two streams of flue gas
SO2 can be recovered to produce acid.
