Random And Structure Packing

Structured packing is a range of materials that are specially designed for use in distillation and absorption columns, as well as chemical reactors. They usually consist of thin corrugated metal plates or gauzes, designed to force fluids on complicated paths throughout the column. The design is intended to ultimately produce a large surface area for contact between different phases.

Structured packing is made from a variety of materials including corrugated sheets of perforated embossed metal or wire gauze. The resulting product is an open honeycomb with inclined flow channels producing a high surface area coupled with a low gas flow resistance. Enhancements are often chosen to maximize liquid spreading which are ideal for applications with low pressure and irrigation rates
