PROCESS AND APPARATUS FOR THE REMOVAL OF HYDROGEN SULPHIDE FROM A GAS MIXTURE

摘要

Process for the removal of hydrogen sulphide from a gas mixture comprising passing the gas mixture through a reactor (2) filled with catalyst for the conversion of hydrogen sulphide to carbonyl sulphide, and separating the gas mixture leaving reactor (2) in a separator (7) at a temperature below the boiling point of carbonyl suplhide in a lighter fraction and a heavier fraction in which the carbonyl sulphide is absorbed.
