Abstract

A column for mass exchange between a liquid and a gas includes at least one pair of adjacent exchange plates, formed by an upper exchange plate and a lower exchange plate. The column also includes a drain shaft for passing liquid between the upper exchange plate and the lower exchange plate, and a recessed inlet cup located underneath a bottom end of the drain shaft. The bottom of the inlet cup is recessed relative to the surface of the lower exchange plate. The recessed inlet cup extends over only one part of the cross-section of the bottom end of the drain shaft.
