Metallic Cascade Mini Ring <CMR> Random Packing

Desulphurization and decarburization system in compound ammonia plant, decompressing plant in crude oil separated plant.

Cascade Mini Ring/ Random Packing :

High Operational efficiency occurs because of the preferential orientation which ensures that in most of the ring surface are positioned vertically rather than horizontally, and this is also advantageours for mass transfer. High efficiency is dependent on as much of the available surface area as opssible being effectively wetted. The underside of any horizontal surface in a packed bed or tower is naturally, shielded from the liquid trickling down and is therefore not fully wetted, such dry surfaces play little or no part in the mass transfer process. CMR packing significantly reduce this effect.
