Metal Random Packing and IMTP(tm) Packing
Metal Random Packing is a common method of liquid and vapor mass transfer. It has been successfully used in distillation, absorption and extraction operations for many years.
Random packings can be made from metals, plastic and ceramic materials. They are available in different sizes to suit a range of processes and efficiency requirements.
The best random packing for your process will balance capacity/pressure drop, efficiency and cost. It should also be able to withstand compression, fouling and corrosion so that it can last for many years.
Capacity is the amount of liquid or vapor that can be handled by the random packing. It can be increased with more space in the packing pieces, which reduces friction and allows more void space for the vapor to move upward through the tower.
Choosing the Right Random Packing
A good random packing should have a high surface area, which provides an effective surface for vapor-liquid contact. This improves the efficiency of the process.
The surface area of a random packing is determined by the size and shape of the pieces in the packing. The larger the pieces, the more surface area per cubic foot of media.
Another way to increase the surface area of a random packing is to select a material that has lower friction. This lower friction makes it easier for the vapor to move through the media.
Other ways to increase the surface area of a random pack are to use materials that can resist heat and temperature. This is important for applications such as chemical separations, where the temperature of the vapor may change.
A high surface area can also be achieved by choosing the material that is corrosion-resistant. This is essential in some industries such as the oil and gas industry, where a random pack may be subject to acid and alkali conditions.
Some other benefits of using random packing are that it is unbreakable, has a high turndown and can be manufactured to meet a wide range of specifications and operating conditions.
Developed in the late 1970s, IMTP(tm) Random Packing is an updated version of the older saddle type packing that incorporates modern ring type random packings. It offers a lower pressure drop at the same vapor and liquid loads as other generations of random pack.
The IMTP(tm) random pack is designed to provide a high level of stability for distillation and absorption columns. This packing can be combined with state-of-the-art INTALOX(tm) Packed Tower Systems column internals to ensure performance and reliability.
A random packing can be made from a variety of materials such as steel, carbon, copper, brass, stainless steel and other alloys. It is often used in the chemical and metallurgy, coal gas and environmental protection industries to separate gases and liquids in distillation and absorption towers.
METAL VSP RING
Metallic VSP rings has reasonable geometric symmetry, which the inner arc are folded evenly along the axial direction and replaced alternated arranged. This design contributes a continuous surface for extremely high voidage and evenly distribution. Compared with pall ring, the fluxes are increased 15-30% and the pressure drop is reduced 20%–30%.
