At proper operating Temperature: WebAround 200 million metric tons of sulphuric acid is manufactured per year- Most of it from strong SO 2 (~12%) gas. SO 2 in smelting and roasting gas accounts for about 30% of sulfuric acid production. Two and a half to four tonnes of sulphuric acid are produced for every tonne of copper smelted from sulphide concentrates [5].
WebMar 16, 2012 · In the usual contact plants 97-98% of the SO 2 is oxidized to SO 3 while the remaining 2-3% nonoxidized S0 2 are emitted. The stack gas generally contains 0.2-0.3% by volume SO 2.Through changing to the Bayer Double Contact process, the conversion can be raised to 99.5% or higher.The sulfuric acid can be produced at the same cost as … WebThe process can be divided into four stages: Combining of sulfur and oxygen (O 2) to form sulfur dioxide, then purify the sulfur dioxide in a purification unit Adding an excess of …
