An apparatus and process for removing acidic gases from flue gases produced by processing operations of the type carried out in utility and industrial plants. The apparatus is generally a gas-liquid contactor (10) whose operation involves the entrainment of a contact medium in an upward-flowing, high-velocity flue gas so as to promote the removal of constituents from the gas. While substantially complete removal of the entrained contact medium is problematic for the high-velocity flue gas, the apparatus, prior to demisting of the gases, redirects the gases containing the entrained contact medium from the upward flow direction to a downward flow direction so as to impact a body (22) of fluid in a container (18), and the gases are then flowed horizontally through a horizontal flow passage (30) at a reduced velocity to further separate the entrained contact medium from the gases.

L'invention concerne un dispositif et un procédé pour l'élimination des gaz acides dans les fumées résultant d'opérations de traitement comme les opérations conduites dans les installations de service et les installations industrielles. En règle générale, le dispositif est un contacteur gaz-liquide (10) qui permet d'entraîner un milieu de contact dans des fumées passant à grande vitesse de manière à favoriser l'élimination des composants acides, puis on retire entièrement le milieu de contact entraîné avant de procéder au désembuage des gaz.
