The column comprises at least one collector tray (1), at least one packed bed, and mixing means for a gas flow (7, 8). According to the invention, the mixing means for a gas flow are arranged below the collector tray (1) and above the packing. ## Claims ### Claim 1 1) A column for exchanging heat and/or material between a gas and a liquid, comprising at least one collector/distributor tray (1), and at least one packing (17) for placing gas and liquid fluids in contact, said collector tray (1) distributing said fluids over said packing (17), said column further comprising mixing means (8, 10, 11, 14, 15, 18, 19) for a gas flow, characterized in that said mixing means for the flow of said gas are arranged below said collector tray (1) and above said packing (17), and in that said mixing means for the flow of said gas are configured to distribute the gas flow over substantially all of the section of the column. ### Claim 2 (depends on 1) 2) The column as claimed in claim 1, in which said mixing means are configured to drive the gas flow in a direction substantially parallel to the axis of said column. ### Claim 3 (depends on 1) 3) The column as claimed in claim 1, in which said mixing means are configured to drive the gas flow in a substantially radial and/or ortho-radial direction relative to said column. ### Claim 4 (depends on 1) 4) The column as claimed in claim 1, in which said mixing means are substantially parallel to said collector tray (1). ### Claim 5 (depends on 1) 5) The column as claimed in claim 1, in which said mixing means for the flow of said gas comprise at least one plate (8) deflecting at least a part of the current lines of said gas flow. ### Claim 6 (depends on 5) 6) The column as claimed in claim 5, in which said plate (8) is fixed relative to said collector tray (1). ### Claim 7 (depends on 5) 7) The column as claimed in claim 5, in which said plate (8) is rotationally mobile about an axis. ### Claim 8 (depends on 5) 8) The column as claimed in, claim 5, in which said plate (8) is substantially in the shape of a half-disk, a helix, a paddle, a blade or an inverted U. ### Claim 9 (depends on 5) 9) The column as claimed in claim 5, in which said plate (8) is mounted on a rod (7) fixed to said collector tray (1). ### Claim 10 (depends on 5) 10) The column as claimed in claim 5, in which said collector tray (1) comprises a distribution system comprising at least one supply conduit (5) protruding below said collector tray (1), said plate (8) being mounted on said supply conduit (5) of said distribution system. ### Claim 11 (depends on 5) 11) The column as claimed in claim 5, in which said mixing means for the gas flow comprise a number of plates (8) arranged one below the other. ### Claim 12 (depends on 3) 12) The column as claimed in claim 3, in which said mixing means for the flow of said gas generate a cyclonic movement of said gas flow. ### Claim 13 (depends on 12) 13) The column as claimed in claim 12, in which said mixing means for the gas flow comprise at least one blade (10) oriented toward the center of said column. ### Claim 14 (depends on 12) 14) The column as claimed in claim 12, in which said mixing means for the gas flow comprise a deflector having a substantially helical shape of the worm screw type at the center of said column. ### Claim 15 (depends on 1) 15) The column as claimed in claim 1, in which said collector tray comprises a distribution system comprising at least one conduit (5) protruding below said collector tray (1), and in which said mixing means for the flow of said gas comprise a dry packing (11) arranged around said conduit (5) of said secondary distribution system. ### Claim 16 (depends on 1) 16) The column as claimed in claim 1, in which said mixing means for the flow of said gas comprise means (14, 15) for restricting the gas passage section. ### Claim 17 (depends on 16) 17) The column as claimed in claim 16, in which said restricting means (14) direct the flow of said gas to the periphery of said column. ### Claim 18 (depends on 16) 18) The column as claimed in claim 16, in which said restricting means comprise at least one chicane (15). ### Claim 19 (depends on 1) 19) The column as claimed in claim 1, in which said mixing means for the gas are formed by a distribution system linked to said collector tray (1). ### Claim 20 (depends on 19) 20) The column as claimed in claim 19, in which said distribution system comprises at least one conduit (5) protruding below said collector tray, and a plurality of pipes (18) linked to said conduit (5), said pipes (18) being arranged substantially according to the generatrices of a cone, the axis of which corresponds substantially to the axis of said column so as to direct the gas. ### Claim 21 (depends on 19) 21) The column as claimed in claim 19, in which said distribution system comprises at least one conduit (5) protruding below said tray, a gutter (19) linked to the conduit, and a plurality of pipes (6) linked to said gutter (19), said gutter (19) comprising at least one orifice (20) for the passage of the gas. ### Claim 22 (depends on 1) 22) A method of gas treatment, acid gas capture, distillation, dehydration or air separation, comprising subjecting a feed to effective condition in a column according to claim 1.
