Metal packing is made of carbon steel, stainless steel and composite gold and other materials. Metal packing has the advantages of thin wall, cold and heat resistance, large void ratio, large flux, low pressure, low resistance, good separation effect, long life, etc., although the one-time investment is slightly larger, it can give full play to the potential force of the equipment. Metal packing is suitable for vacuum distillation tower, processing allergic, easy to decompose, easy to compact, easy to bind carbon materials. Metal packings are widely used in packing towers in petrochemical, fertilizer, chemical, environmental protection and other industries. Metal random packing has three Y ring, conjugate ring, eighty-four inner arc ring, flat ring, moment saddle ring, step ring and other products.

Plastic packing materials include PE,PP,RPP,PVC,CPVC,PVDF and so on. It has good corrosion resistance, large void, large flux, small resistance, low energy consumption, low operating costs, light weight, easy handling and reusable. Especially suitable for oil, chemical, chlor-alkali, gas, environmental protection and other industries in the medium and low temperature (60-150 degrees) distillation, absorption and washing tower.
Plastic packing includes: Pall ring, moment saddle ring, heterosaddle ring, ladder ring, Haier ring, conjugate ring, flat ring, Koster wreath, empty floating ball, multi-faceted ball, net cage ball and cover ball and so on.

Metal structured packing is mainly composed of parallel arranged metal mesh or metal wire, showing a regular geometric shape, such as cylinder, ball and so on. This structure can increase the surface area of the packing, improve the contact frequency of the reactants inside the packing, and promote the chemical reaction. It is a commonly used chemical reactor packing. It is usually made of metal mesh or wire braided, has a high surface area and good mass transfer performance, and plays an important role in the chemical reaction process. This paper introduces the structure, preparation method, application field and advantages of packings.
