Abstract

Improved gas liquid contact sheets and contact bodies are disclosed comprising a plurality of parallel and generally vertical corrugated contact sheets, wherein the corrugations form alternating apices in the sheets, the corrugations being disposed at an angle to the horizontal and wherein the corrugations are substantially parallel and adjacent sheets are oriented such that corrugations of one sheet cross the corrugations of an adjacent sheet at intersections of the apices, the improvement comprising positioner pads positioned in apices of the corrugations of the contact sheets, such that at least about eighty percent of the intersections of adjacent sheets contain abutting pairs of the positioner pads. In addition, contact bodies in which adjacent sheet corrugations intersect proximate the edges of the contact sheets are provided.
