Metal Structured Packing Material
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, plastic, 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.
Metal Structured Column Packing Advantages
- 1. High number of theoretical plates, large flux and low pressure
drop;
- 2. Good performance with low working load, increased number of
theoretical plates with the decrease of gas load, and there is
almost no bottom limit of work load;
- 3. Large operation elasticity;
- 4.No obvious amplification effect
