A process and device for scrubbing flows of gaseous effluents loaded with polluting substances, wherein the effluents are caused to circulate through a device including an array of scrubber units (4a to 4n) juxtaposed in an enclosure (3), each containing materials adsorbing the substances. When the adsorbing load thereof is saturated and for the scrubber units (4) to regain the scrubbing capacity thereof, they are selectively and successively isolated by a mobile collector (8) during the time required for their desorption by heating and for the substances to be transferred by an auxiliary fluid (a fraction of the circulating effluents for example or a gas delivered selectively to the inlet of the scrubber unit to be desorbed by an auxiliary circuit), and the substances mixed with the auxiliary fluid are possibly transferred towards a reactor (10) suited for removing them. The process can be applied for concentrating and scrubbing of polluting substances such as VOCs or gas dehumidification.

[ We claim:] [1.] A process for scrubbing gaseous effluents containing unwanted substances, wherein the effluents to be scrubbed are driven towards a scrubbing barrier placed across an enclosure, including a plurality of scrubber units containing a material suited for adsorbing and concentrating said substances, and the various scrubber units are selectively and successively isolated by means of a mobile collector when the adsorbing load thereof is saturated, so as to drive a desorption fluid therethrough, comprising selective thermal desorption of at least one scrubber unit combined with destruction of the substances obtained by selective desorption.
