  • Patent number: 4595575
    Abstract: The invention relates to a process for the continuous wet or wet-catalytic purification of waste gases by adsorption and chemisorption of the gaseous pollutants on activated carbons with simultaneous desorption of these pollutants or their reaction products. The process is carried out at 100 to 800 times gravity acceleration in a centrifugal filter, in the rotor of which a bed of fine-grain or fibrous activated carbon is arranged. The waste gas passes through this bed in codirectional or counter-current flow to the wash liquid. The pollutants are washed out with the desorbent flowing from the center outwardly.
