Abstract: The device for producing and treating a gas stream (F) includes an exchange enclosure (2) having at least a first discharge opening (2b) for a gas stream, means (3; 4) for supplying the enclosure with a liquid (L), means (3; 5) for discharging the liquid (L) contained in the exchange enclosure (2) and aeraulic means (6), which make it possible, during operation, to create, by means of suction or blowing, an incoming gas stream (F) coming from outside the exchange enclosure (2), so that said incoming gas stream (F) is introduced into the volume of liquid (V) contained in the exchange enclosure (2), and an outgoing gas stream (F?), treated by direct contact with said volume of liquid, rises inside the exchange enclosure and is discharged out of the exchange enclosure (2) through the discharge opening (2b).

Abstract: A device for producing and treating a gas stream is provided that includes an enclosure, of which the lower part is submerged in a liquid supply open at the top and includes at least one liquid intake opening. The submerged lower part of the enclosure contains a volume of this liquid and at least one opening for discharging a gas stream, positioned above the surface of the volume of liquid contained in the enclosure. The device further provides for injecting a gas stream including at least one injection conduit and extends in the upper part inside the enclosure outside the volume of liquid. During operation of the device an incoming gas stream is introduced to create an outgoing gas stream, treated by direct contact with said volume of liquid that is discharged outside the enclosure. A facility inclusive of the device and method of operation are also provided.

Abstract: The facility (1A) includes at least two treatment devices (2) each with an exchange chamber (20) intended to contain a liquid bath in the bottom part and at least one injection line (21). An aeraulic means (4), creates by suction or by blowing, simultaneously and in parallel for each treatment device (2), an incoming gas stream (F) originating from outside the exchange chambers (2) and passes through the discharge opening of the injection line (21) by being introduced into the liquid bath contained in the bottom part of the exchange chamber (20), below the surface (S) of said liquid bath. The exchange chambers (20) communicate hydraulically with one another so that when the aeraulic means (4) are shut down, each exchange chamber (20) is suitable for containing or contains, in the bottom part, an initial volume (Vinitial) of liquid, with an initial liquid level (Hinitial) that is identical in all the exchange chambers (2).
