ABSTRACT:
Process tower vapor-liquid contact method and apparatus comprising stacks of corrugated contact plates having perforated lamella disposed therebetween. The corrugated plates are disposed in face-to-face contact with respective corrugations inclined to the horizontal and separated one from the other by a perforated sheet. The assembly affords optimal pressure drop characteristics, surficial area, vapor passage area, and vapor-liquid distribution characteristics with maximum efficiency. The sandwiched plate separating adjacent corrugated contact plates greatly increases the mass and heat transfer between the liquid and vapor phases passing thereacross by effectively segregating opposed corrugated channels and establishing a plurality of vapor-liquid contact areas positioned for engaging both vapor and liquid flow in opposed directions through the oppositely inclined corrugations of adjacent plates. In this manner the notional plane is defined between stacks of inclined corrugated contact plates and provided in a configuration providing multiple mass and heat transfer points between adjacent corrugations and the flows directed therethrough wherein the vapor-liquid contact is maximized with a minimum of pressure drop.
