Among the different types of random packings available in the market, the metal cascade mini ring has a lot of advantages and is able to satisfy most of the requirements of users. It has a thin wall, high free volume, low resistance, low-pressure drop, and high separation efficiency. It can be used in a wide variety of rectification towers for the treatment of thermosensitive, decomposable, or polymerizable systems.
This kind of random packing is manufactured from carbon steel, stainless steel, or aluminum alloy. It has a high ratio of height-diameter, and the cone flanging increases the gas-liquid contact area.
The structural design of the cascade mini ring greatly promotes the renewal of the surface of the liquid membrane, which strengthens its mass transfer performance. The flanging, in particular, is also important for improving its fouling resistance, because it makes it easier to flush any solids that are present within the packed bed.
There are several benefits to using a cascade mini ring in your reaction tower, and the main ones are:
Higher capacity: The lower aspect ratio of the cascade mini ring allows it to be used in deeper packed beds than other random packings. This increases its capacity and helps to reduce the pressure drop.
Better fouling resistance: Fouling resistance is one of the key features to look for in any random packing. The cascade mini ring is able to resist the corrosive properties of acidic solutions and prevent any solids from accumulating in the packed bed, thus making it much more resistant to fouling than other random packings.
Fouling resistance can be achieved in many ways, but the most effective is to ensure that the ring has open sides. This allows any solids that are present in the packed bed to be easily flushed downwards via the packing matrix of the liquid.
Chemical and heat resistant: The cascade mini ring is made from heat resistant and chemical corrosion-resistant materials, which means that it can be used in harsh environments without compromising its performance. It can be produced from a variety of heat-resistant and corrosion-resistant plastics, including polyethylene (PE), polypropylene (PP), RPP, reinforced polypropylene (RPP), PVC, CPVC and PVDF.
The cascade mini ring is a new type of random packing, which was developed by British company MTL Ltd. The ring has rectangular openings, a curved blade and a conical edge. It also has a reduced height and flanging on the edges of the ring wall.
It is a new type of random packing, whose structural design significantly improves the flow and distribution in a packed bed. This also increases the mechanical strength of the ring.
It is used in drying columns, absorbing columns, cooling towers and scrubbing towers in chemical industry, metallurgy, coal gas industry and oxygen producing industry. It has good capacity and resistance to fouling and is a versatile packing that can be used in both small and large-diameter mass transfer towers.
METAL NUTTER RING
Nutter Ring is a king of high performance packing with good geometry structure provides minimum accumulation and maximum randomness. Compared with the corresponding size of pall rings, it can increase the flux by 10%, while the pressure drop was only 40% of pall ring.
