Abstract
THE INVENTION RELATES TO A PROCESS FOR SCRUBBING A GAS CONTAINING HYDROGEN SULPHIDE AND / OR CARBONYL SULPHIDE, IN WHICH THE SPENT SCRUBBING LIQUID IS TREATED WITH AUTOTROPHIC SULPHIDE-OXIDISING BACTERIA CAPABLE OF OXIDISING AT HIGH PH, AND ELEMENTAL SULPHUR IS OBTAINED, THE ELEMENT SULPHUR IS SEPARATED AND THE TREATED SCRUBBING LIQUID IS RECYCLED TO THE GAS SCRUBBING STEP. BEFORE RECYCLING, THE SCRUBBING LIQUID MAY FURTHER BE TREATED WITH HETEROTROPHIC THIOSULPHATE-OXIDISING BACTERIA WHICH PRODUCE POLYTHIONATE WHICH IS USEFUL FOR FURTHER ENHANCING THE SULPHIDE-SCRUBBING CAPACITY OF THE SCRUBBING LIQUID.
