METAL CASCADE MINI RING

METAL CASCADE MINI RING

Metal cascade mini ring is also called metal cascade ring, metal cascade mini ring packing. It is a new type random packing. Metal cascade mini ring has rectangular openings, curved blade, conical edge and reduced height. Its structural design effectively increases the gas-liquid contact point and improves the gas-liquid distribution in the packed bed. The design greatly promotes the renewal of liquid membrane's surface and strengthens cascade ring's mass transfer performance. This kind random packing has higher mass transfer efficiency and better separation effect than the metal intalox saddle and metal raschig ring.


Materials and Options
Available in a wide range of materials such as stainless steel 304, 304L, 316, 316L, carbon steel , aluminum and other alloy etc.

Advantage

1) Reduced pressure drop

Reduced Pressure drop occurs because the Cascade Mini 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.

2) Increased plant capacity

Increased plant capacity is the direct result of the result of the reduction in pressure drop that Cascade Mini Rings provide, as this moves the operating point further away from the critical pressure drop point at which flooding occurs. This effect allows additional vapor/liquid handling and therefore increases plant capability.

3) Improved resistance to fouling.

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.

4) Higher operational efficiency

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.  Cascade Mini Ring significantly reduces this effect,and therefore gives much higher plant operational efficiency.

Applications and Industries

Metal cascade mini ring packing is widely used as tower packing in carbon dioxide degassing tower, ozone contact reaction tower, mist purification tower and synthesis reaction column.
