✦ Synopsis

A two-stage or two-circuit scrubber is implemented for the desulfurization of flue gas from electric power plants. An absorption agent suspension is charged into an upper circuit of the scrubber and oxidation air is charged into a lower circuit of the scrubber. To eliminate sulfite deposits in the upper circuit, the sulfites are oxidized to gypsum by feeding of an additional amount of air into the suspension at any point of the upper circuit and/or into a container for the circulating absorption agent.
