Due to its excellent performance, metal pall ring packing is widely used in many fields such as chemical industry, environmental protection, and energy. The following is a detailed introduction:

Chemical industry

Distillation process: In the separation of petroleum cracking gas and aromatics, metal pall ring packing can provide efficient gas-liquid mass transfer, so that components with different boiling points can be better separated and the purity of the product can be improved. For example, in the demethanizer and deethanizer in the ethylene unit, the use of metal pall ring packing can effectively separate light hydrocarbons.

Absorption and desorption: In the synthetic ammonia process, the absorption tower filled with metal pall ring packing can absorb impurity gases such as carbon dioxide and hydrogen sulfide; in the desorption tower, the solution that absorbs impurities can be desorbed to achieve solvent regeneration and impurity gas recovery.

Reaction process: In some gas-liquid reaction processes, such as oxidation reaction and hydrogenation reaction, metal pall ring packing can be used as a catalyst carrier to provide a larger specific surface area, make the reaction more complete, and improve the conversion rate and selectivity of the reaction.
