The invented column for contacting upwardly flowing gas with downwardly flowing liquid comprises at least two trays (3, 5) comprising a plate (6, 7) provided with a tubular gas/liquid contact device (8, 10). The tubular gas/liquid contact device (8,10) comprises a contact section (12) located below the plate (6, 7), separation sections (13) and an outlet section (15) disposed above the separation section (13) and located above the plate (6, 7), wherein the contact section (12) is closed at its bottom, wherein the wall of the contact section (12) is provided with a plurality of tangential gas inlets (16). The outlet section (15) comprises a gas permeable wall provided with coalescent means (25) for recollecting liquid entrained by gas. The top of the outlet section (15) is provided with a cover (27) covering the outlet section (15) from above. A liquid delivery tube (19) of the tubular liquid contact device (10) passes on one tray (5) through the cover (27) of the outlet section (15) th |
