A process for removing sulfur containing compounds from gas containing at least one sulfur containing compound

A process for removing at least a sulfur containing compound from gas containing at least one sulfur containing compound, wherein the process comprises the following steps: (a) contacting a gas stream containing at least one sulfur containing compound with a stream containing bromine and water so as to obtain a starting stream, (b) reacting the starting stream provided in step (a) so as to produce a reaction mixture effluent comprising sulfuric acid and hydrogen bromide, (c) separating the reaction mixture effluent obtained in step (b) into one or more hydrogen bromide enriched compositions and into one or more sulfuric acid enriched compositions, (d) subjecting at least a portion of the at least one hydrogen bromide enriched composition obtained in step (c) to a treatment, in which at least a portion of the hydrogen bromide enriched composition is converted to bromine, (e) recycling at least a portion of the bromine containing composition obtained in step (d) back to step (a), and (f) withdrawing gas, which
