Metallic Cascade Ring

Higher 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 advantageous for mass transfer. High efficiency is dependent on as much of the available surface area as possible 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 . CMC packing significantly reduces this effect,and therefore gives much higher plant operational efficiency.

   Higher operational efficiency

Improved resistance to fouling results from the the directional positioning of the rings,(largest opening in direction of flow ) as any solids entering the packed bed are more easily flushed through the packing matrix

   Improved resistance to fouling.

Increased plant capacity is the direct result of the result of the reduction in pressure drop that CMC rings provide, as this moves the operating point further away from the critical pressure drop point at which flooding occurs. This is typically 1-2 in., wc/ft or 10-20 mbar/in). This effect allows additional vapor/liquid handling and therefore increases plant capability

 Increased plant capacity

Reduced Pressure drop occurs because the Chemshun C-ring has its largest opening predominantly in the direction of the vapor/liquid flow which allows for easy passage, This reduces the pressure drop significantly.

Technical data

Huihua Metal Cascade Mini Rings are widely used in desulfuration and decarbonization system in compound ammonia plant, decompressed plant in crude oil separated plant, all kind of separation process such as separation of methanol, separation of organic acid, and used in absorb or disabosorb tower.

Applications

Good Mechanical Strength,  which allows Huihua Metal Cascade Mini Rings'  use in deep packed beds that have a higher hydraulic capacity.

More resistant to fouling, because a combination of Huihua Cascade Mini Rings'  vertical alignment and open sides, allow any solids present to be flushed downwards through the packed bed.

The lower pressure drop and higher throughput of Huihua Metal Cascade Mini Rings enables a smaller column diameter and fan size to be specified in new installations, The highly exposed internal and external surfaces provide an efficient vehicle for liquidgas contact, by multiple drip-points;

 Huihua Metal Cascade Mini Rings,  preferential orientation in a packed bed with the cylindrical axis in the vertical plane, allows a free passage for gas to flow through it;

Lower aspect ratio (H/D 1/2 to 1/3) increase capacity and reduces pressure drop;

CMR for short, a lower aspect ratio increases capacity and reduces pressure drop and the highly exposed internal and external surfaces give a high efficiency vehicle for liquid gas contact with good mechanical strength.
