Structured packing is a type of material used in distillation and separation processes to create a large surface area for efficient contact between vapor and liquid phases. Unlike traditional trays, which involve perforations and bubble caps, structured packing consists of specifically designed arrangements of sheets, grids, or other shapes that provide a high surface area for mass transfer.
The purpose of structured packing is to enhance the separation efficiency of distillation columns by providing ample surface area for vapor-liquid interaction, without the need for complex mechanisms like bubble caps or sieve holes. Here are some key features of structured packing:
