METHOD FOR PURIFICATION OF EXHAUST GAS OF SULFUR PRODUCTION Russian patent published in 1995 - IPC

Abstract RU 2031696 C1

FIELD: methods of purification. SUBSTANCE: gas is passed through catalyst which represents pure titanium dioxide, or titanium dioxide containing 1-20 mass % of calcium, or strontium, or barium sulfates. The process is carried out at 250-350 C, it is followed by cooling gas. Thus prepared gas is then treated at 100-160 C to produce elementary sulfur, mass ratio H₂S : SO₂ being 2:1. EFFECT: improves efficiency of the method. 3 cl, 1 tbl, 1 dwg
