SS304 304L 316L 316L Metal Cascade Mini Ring, Hooked CMR

SS304 304L 316L 316L Metal Cascade Mini Ring, Hooked CMR

Short Description:

Cascade mini ring is made of materials like carbon steel, stainless steel or Aluminum alloy, etc. The product has features such as thin wall, heat resistant, high free volume, high capacity, low resistance, high separation efficiency and so on. It is especially suitable for rectification towers under vacuum to treat thermosensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.

Description

Metal Cascade Mini Ring, a lower aspect ratio (H/D1/2to1/3) increases capacity and reduces pressure drop and the highly exposed internal and external surfaces give a high efficiency vehicle for gas-liquid contact with good mechanical strength. Preferential orientation in a packed bed with the cylindrical axis in the vertical plane, allows a free passage for gas to flow through it.
Metal cascade mini ring overall performance is better than pall ring, currently it is the most excellent well known packing.

Advantage

●  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.

 ●  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 is typically 1-2 in., wc/ft or 10-20 mbar/in). This effect allows additional vapor/liquid handling and therefore increases plant capability

 ●  Improved resistance to "fouling"

Improved resistance to fouling results from 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.

 ●  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.

Application

It is mainly used in washing towers, cooling towers, desulphurization towers, deaerator, drying towers and de-carbon towers,as well as facilities for sewage treatment.
