OXYSULF SCUH₂SO₄ & SO₂  production

download OXYSULF SCU flow diagram

OXYSULF SCU is applied when SO₂ and H₂SO₄ production is required. Liquid sulfur is fed into a specially designed combustion chamber to form SO₂. The resulting process gas is fed into the scrubber to absorb the small quantity of potentially formed SO₃. After the scrubber, part of the SO₂ is cooled and condensed. The remaining SO₂ is sent to the OXYSULF HK plant where the conversion of SO₂ to SO₃ and then the hydrolysis to sulfuric acid takes place.
