The invention concerns a method and an equipment (10) for recovery and treatment of sulphur dioxide (SO2) contained in exhaust gases. In the method, the flue gases are passed as a flow (13) into the washer part (11), and the sulphur dioxide (SO2) contained in the flue gases is dissolved into the washing liquid passed into the washer part (11). The mixture that contains sulphur dioxide (SO2) and that has been dissolved into the washing liquid is passed along a flow line (17) into a liquid container (12). The mixture that is placed in the liquid container (12) and that contains sulphur dioxide (SO2) is oxidized at a pressure of free choice, by means of a gas, preferably air, that is placed in the liquid container (12) and that contains oxygen (O2), into sulphur trioxide (SO3), which forms sulphuric acid (H2SO4) together with the water present in the liquid container (12).
Procédé et installation (10) de récupération et de traitement du dioxide de soufre (SO¿2?) contenu dans les gaz d'échappement. Selon ce procédé, les gaz de rejet sont admis sous forme de flux dans la partie de lavage (11), et le dioxide de soufre (SO¿2?) contenu dans ces gaz de rejet est dissous dans le liquide de lavage lors de son passage dans cette partie de lavage (11). Le mélange contenant le dioxide de soufre (SO¿2?) et ayant été dissous dans le liquide de lavage est acheminé par une conduite (17) dans une cuve à liquide (12). Le mélange envoyé dans la cuve (12) et contenant du dioxide de soufre (SO¿2?) est oxydé, à une pression librement choisie, à l'aide d'un gaz, de préférence l'air, qui est admis dans la cuve (12) et contenant de l'oxygène (O¿2?), pour obtenir du trioxide de soufre (SO¿3?), lequel forme de l'acide sulfurique (H¿2?O¿4?) en présence de l'eau contenue dans la cuve (12).
