According to the process according to the invention: the gaseous flow (1), as well as a reducing reagent (3) and an oxidation inhibitor (4), are introduced into a wet scrubber (101), starting from less the measurement of the redox potential of a purge (5) leaving the scrubber (101), the quantity of the oxidation inhibitor (4) introduced into the scrubber is controlled, and - from at least the measurement, directly or indirectly, the concentration of reducing reagent (3) in the purge (5) leaving the scrubber, the amount of reducing reagent introduced into the scrubber is controlled. |
