A structured packing for producing intimate contact between descending liquid and ascending vapour phases formed of a plurality ofjuxtaposed sheets 10, 20 and 30 through which the liquid phase descends as a film. The sheets have corrugations to define flow channels through the sheets for the vapour phase to ascend through the structured packing and contact the liquid phase. The sheets have a plurality of projections, situated on one or both sides of each of the flow channels and/or each of the sheets. The projections are configured and oriented to produce turbulent mixing in the vapour phase as it ascends the packing. This turbulence inhibits the formation of a concentration gradients within the vapour phase in directions normal to the walls of the flow channels. The projections are spaced apart from one another so that the turbulence in the vapour phase subsides between the projections. <IMAGE> |
