Sulfuric Acid Manufacturers – Breen Energy Solutions

Sulfuric Acid is manufactured by oxidizing SO 2 gas to SO 3 in a converter through a catalytic oxidation process.. The most common sources of SO 2 are:. Burning elemental Sulfur; SO 2 off-gas from a primary process such as a copper smelter; Decomposition of H 2 SO 2 in a spent acid regeneration process; The SO 2 gas as produced above is passed over a catalyst in the presence of Oxygen to

The Double Contact Process For Sulfuric Acid Production

Mar 16, 2012In 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 with the single contact method, since the additional
