Abstract

On effectue une mise en oeuvre de plusieurs étapes de mise en contact étagée en mode courant croisé dans une succession de zones de contact dans lesquelles le gaz s'écoule selon une direction essentiellement horizontale en croisant le liquide qui s'écoule selon une direction essentiellement verticale. Le gaz à traiter arrivant par le conduit 1 circule successivement dans les contacteurs à courant croisé C1, puis C2, puis C3 selon une direction sensiblement horizontale. La solution absorbante arrivant par le conduit 7 circule successivement dans les contacteurs C3, puis C2 puis C1. Dans chacun des contacteurs, le liquide circule selon une direction sensiblement verticale descendante.
