Abstract

Process tower vapor/liquid flow distributor and packing bed comprising a plurality of relatively thin corrugated layers stacked one atop the other. The corrugated sheets are disposed in face to face contact with respective corrugations inclined to the horizontal and facing one another for the countercurrent passage of vapor and liquid therethrough. At least two layers are utilized and rotationally offset for diverting the vapor liquid in two separate directions to effect maximum vapor liquid distribution for countercurrent fluid flow passing therethrough. An improved homogenous mixture of vapor/liquid within the process tower packing sections may thus be provided. The assembly affords optimal pressure drop characteristic while maximizing even vapor/liquid distribution into the packing regions. In this manner the distribution sections may be disposed throughout the process tower above and below each packing section, or in place of the packing section for distributing the descending liquid flow as well as the ascending vapor flow therethrough. This configuration maximizes the efficiency of the distribution thereacross and the homogenous mixture interaction therein.
