ABSTRACT:
A process for the production of elemental sulphur by reacting hydrogen sulphide with sulphur dioxide in a liquid reaction medium comprising an organic solvent for the two compounds, e.g., ethylene glycol, and containing at least one soluble catalytic basic compound, e.g., sodium salicylate, comprises bringing a gas mixture containing sulphur dioxide and hydrogen sulphide into contact with a co-current of the solvent containing the catalytic basic compound.
