Structured packing of well-known geometry with an alternating arrangement of individual corrugated sheets forming intersecting open channels for the vapor flow was developed at Sulzer Winterthur in the 1960s. Low pressure drop(high open area and used for vaccume distillation) 3. Sulzer GTC’s structured packing is designed to help clients achieve higher capacity, higher efficiency and lower pressure drop. Although these studies might reveal some tendency of the packing efficiency for different types and materials, it is important to emphasize that they should not generalize the comparisons. Hi, Structured packing is a universal packing type that is suitable for a variety of applications. Figure 8.11 (Continued) Common corrugated-type structured packings, (c) Gempak®;
