One of the primary devices used in mass and heat transfer applications is random tower packing. It helps create a larger surface area so that the vapours can come in contact and bring forth chemical separation.
Now, when it comes to choosing the right random tower packing, there are several options you can go for. Moreover, with a wide variety of materials they are available in – metal, ceramics and plastic – it becomes increasingly important to go for the right one.
Here are the numerous new generation random tower packing produced in South Africa.
Plastic Pall Rings
If you are looking to utilise random tower packing for absorption, desorption, degassing, heat recovery, distillation, aeration, or stripping, plastic pall rings are your best bet. Whether it’s a chemical processing plant, water treatment and sewage plant, or air pollution control scrubber systems, plastic pall rings show incredible performance. These plastic versions are much better than other options available since they are cost-effective, corrode less and are suitable for extremely low temperatures.
Plastic Beta Rings
Plastic Beta Rings are one of the most important forms of random tower packing. They enable gases and liquids to flow uninterrupted. This flow is made possible with an increased hole size on the plastic beta rings as well as additional drip points that are smartly designed. They offer high vapour capacity and are mechanically robust. This means that plastic beta rings can withstand a lot of pressure and corrosion. These plastic beta rings also offer very high absorption efficiencies for both liquids and gases.
Plastic Cascade Rings
Plastic cascade rings are quite possibly the most operationally crucial elements in any random tower packing. Best used in deep pack beds, plastic cascade rings are beneficial for absorption and stripping systems, decarbonisation systems, desulphurisation processes, and crude oil separation systems. Since plastic cascade rings are smaller than plastic pall rings, they offer way less resistance. Moreover, the plastic material is highly beneficial for low temperatures and high corrosion situations. Plastic cascade rings are also very sturdy when it comes to changes in liquid distribution, thus offering high performance.
While plastic pall rings, plastic beta rings, and plastic cascade rings are better suited for lower temperatures and highly corrosive environments, ceramic saddles are better suited for high-temperature environments where the chances of acid corrosion are severely high. Ceramic saddles are a great form of random tower packing that offer impressive acid resistance even at super high temperatures. Ceramic saddles are best suited for chemical processing, petrochemical, metallurgical, fertiliser, pharmaceutical and acid plants. Their larger and smoother surface area also promotes optimal chemical reactions to take place.
Last but not least, plastic saddles are another vital type of random tower packing. These plastic saddles are again suitable for high corrosion and low-temperature environments where you require high flooding points. The mass transfer efficiency is very high when it comes to this random tower packing. They are not just mechanically reliable but also offer good interlocking capabilities. Plastic saddles are best suited for use in the pulp and paper, petroleum, chemical and mining industry.
