The system (1) for sulphur removal from a flue gas (FG), the system (1) comprising an absorber (2) comprising, a vessel (3) having an inlet (4) and an outlet (5) for the flue gas (FG), nozzles (6) for spraying a slurry (7) through the flue gas (FG) and a slurry accumulation zone (9) at the lower part of the absorber (2), a reaction tank (15) having an oxidizing gas supply (16) into it and connected to the slurry accumulation zone (9), a buffer tank (28) connected to the reaction tank (15) and to the nozzles (6), for receiving the slurry (7) from the reaction tank (15) and supply the nozzles (6) with the slurry (7). The slurry accumulation zone (9) is connected to the reaction tank (15) by a duct (21) comprising a gas lock. The buffer tank (28) is connected to the reaction tank (15) by a communicating vessel passage (29). |
