Abstract

Dans ce procédé on extrait l'anhydride sulfureux des gaz à purifier, avec un liquide de lavage qui contient en plus des additifs utilisés couramment, un polyacide carboxylique le plus souvent sous forme de sel alcalin. Ce procédé est effectué dans un dispositif constitué par un récipient 6 divisé en plusieurs compartiments, dont l'un 8 reçoit les composés soufre-calcium formés au cours du lavage des gaz, et de l'air arrivant en 12 qui oxyde ces composés; le second 9 est une chambre de réaction où arrive la chaux en 21 et le troisième 10 est une chambre de détente. Les constituants précités sont enlevés par un convoyeur à raclettes 22 et sont sortis en 23. Ce procédé est plus efficace et plus économique en coûts et en installation.
