A liquid distribution model based on packing structure was developed for metallic corrugated plate packings. The model was verified by experimental results obtained in a 200mm-diameter and a 500mm-diameter column packed with type-4.5 or type-6.3 stainless steel corrugated plate packings. Further investigation showed that metallic corrugated plate packings are superior in liquid distribution behavior to Raschig rings

Pall rings and Cascade rings. From experimental measurements

the density of available wetting points is proposed for liquid distributor design.
