摘要：
The invention is directed to a process to continuously treat a hydrogen sulphide comprising gas, said process comprising the following steps: (a) contacting the hydrogen sulphide comprising gas with an aqueous alkaline liquid comprising sulphide-oxidising bacteria and elemental sulphur particles thereby producing a loaded aqueous liquid comprising dissolved sulphide, polysulphide compounds, sulphide-oxidising bacteria and elemental sulphur particles and a gas having a lower content of hydrogen sulphide, and passing the loaded aqueous liquid through a polysulphide reactor zone comprising one or more plug flow reactor zones, (b) contacting the loaded aqueous liquid with an oxidant to enable the sulphide- oxidising bacteria to oxidise sulphide to elemental sulphur, thereby producing an enriched aqueous liquid comprising an increased amount of elemental sulphur particles and (c) separating elemental sulphur particles from the enriched aqueous liquid, wherein the residence time of the loaded aqueous liquid between its preparation in step (a) and its supply to step (b) is between 3 and 45 minutes, and wherein the content of elemental sulphur as part of the polysulphide compounds in the loaded aqueous liquid [s° in Sx2"j as supplied to step (b) is above 0.7 mM.
