Distillation structured packing GOODLOE®

GOODLOE packing can generate HETP (height equivalent to a theoretical plate) values as low as 2-3 inches (50-75 mm) in pilot columns, and values of 4-10 inches (100-250 mm) in production columns. These high efficiencies are possible because of the high ratio of surface area-to-volume inherent in the GOODLOE packing design. GOODLOE packing is produced by knitting multiple fine metallic filaments that are then crimped and either spiral wound or folded and layered into elements for insertion into the tower. The open structure that results creates multiple twisting paths for the vapor to travel while providing a high void fraction that minimizes pressure drop. At the same time, the inherent capillary action of the fine wires causes the liquid to spread into thin films that continuously combine and divide for optimum mixing and contact with the vapor throughout the entire packing volume. The resilient properties of the packing construction assure firm contact with the tower wall, minimizing the possibility of vapor bypassing or liquid channeling. The net result is a packing with very high mass transfer efficiency and low pressure drop.
