Abstract
A high capacity and high efficiency co-current and cross-flow vapor-liquid contacting apparatus and process is useful in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of offset contacting modules in horizontal stages. The modules define a co-current contacting volume and in an exemplary configuration the modules include a liquid distributor and a demister. Half modules comprise downcomers against the shell of the vessel for transporting liquid to the subjacent stage.
