Wire Gauze Structured Packing
Koch-Glitsch wire gauze packing is the preferred packing in distillation service for deep vacuum and low-liquid-rate applications. The characteristic of lowest pressure drop per theoretical stage makes wire gauze packing the preferred device for processing specialty chemicals, pharmaceuticals and temperature-sensitive materials.
Wire gauze packing is generally used in small- to medium-diameter columns to achieve the maximum number of theoretical stages in the minimum column height. Because of the capillary effect, the wire gauze material provides an extremely wettable surface for low-surface-tension liquids, resulting in excellent mass transfer efficiency, particularly at very low liquid rates
