ABSTRACT:
A process for effecting mass transfer between a liquid phase and a gaseous phase in a filled-type column having an external shell which accommodates at least one filler-containing basket wherethrough the phases are caused to flow in countercurrent relationship. The process includes the step of feeding the gaseous phase to the at least one basket through a gas-permeable surface thereof which is larger than the basket cross-section, preferably in a prevailing radial flow direction.
