ABSTRACT:
A structured packing for producing intimate contact between liquid and vapor phases formed of a plurality of juxtaposed sheets through which the liquid phase descends as a film. The sheets have corrugations to define flow channels through the sheets for the vapor phase to ascend through the structured packing and contact the liquid phase. The sheets have a plurality of elongated projections, situated on one or both sides of each of the flow chapels and/or each of the sheets. The projections are configured and oriented to produce turbulent mixing in the vapor phase as it ascends though the packing. This turbulence inhibits the formation of a concentration gradients within the vapor phase in directions normal to the walls of the flow chapels. The elongated projections are spaced apart from one another so that the turbulence and the vapor phase subsides between the elongated projections.
