Abstract The invention relates to an absorption tower (so-called scrubber) for gas washing in which the gas is introduced into the lower portion of the tower and flows upwards while making contact with a washing fluid. The tower (4) is provided with one or several washing stages (6-9), each comprising one or several venturi tubes (10) through which the gas is given a speed increase and the washing fluid is discharged through fluid nozzles (25) in the gas flow path. The venturi tubes in each washing stage are led through a common collecting baffle (11) for washing fluid which is then recirculated to the nozzles. Means (26,28,29) for liquid distribution are disposed in the upper portion of each venturi tube (10) and are arranged for fluid distribution in the gas flow in directions forming such angles to the vertical that the fluid flow will not fall backwards into the openings of the venturi tubes even if the gas flow through the tower is interrupted.
