High quality/High cost performance Adsorption Tower Packing Plastic Pall Ring

Description

Plastic Pall Ring packing is a high hole diameter equal to the packing ring, each window there are five tongue leaves, each leaf tongue ring in turn point to heart, upper and lower levels of the location of the opposite window at different times and in general Central area of wall openings about the total area of about 30%. With porosity, and pressure drop and low height of mass transfer unit, the pan-point high, vapor-liquid contact with the full, the proportion of small, high mass transfer efficiency.

This structure improves the vapor-liquid distribution, make full use of the inner surface of the ring, so that the tower fill the gas and liquid form from the free passage.
 

Pall rings are widely known as an innovation coming from raschig ring that can be used in various applications, mainly involves gas and liquid transfers. Its walls is intentionally designed to be open geometrically to enable lower pressure drop with greater capacity than on Raschig ring design which is just a standard cylindrical ring.

This pall rings media further maintains uniform distribution and resists wall-channelling inclination. Pall ring suppliers positively push the product's potency to consumers since it has been designed with enough number of contours and crevices to carefully control the liquid and gas transfer rates.

 

 

Plastic pall ring is made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chloridized polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF). It has features such as high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on, and the application temperature in media ranges from 60to 150. For these reasons it is widely used in the packing towers in petroleum industry, chemical industry, alkali-Chloride industry, coal gas industry and environmental protection, etc.


Feature
High free volume, low pressure drop, low mass-transfer unit height.
High flooding point, uniform gas-liquid contact.
Small specific gravity, high mass transfer efficiency.

Advantages
1. The special structure makes it has big flux, low pressure drop, good anti-impaction capability.
2. Strong resistance to chemical corrosion, large void space. energy saving, low operation cost and easy to be load and unload.


Application                             

Pall rings can be applied to various of device of isolation, absorption, deadsorption, common decompression, such as toluene
separation, ethylbenzene separation, isooctane separation and desulfurization system, etc.

 

Types

Stainless steel pall rings

It (also named as ss pall rings) performs high loading and low pressure drop together with an efficient high mass transfer and better liquid/gas distribution. The stainless material brings edge to resist against corrosion.

Plastic pall rings

It is offered in a variety of plastics such as PVDF, Polypropylene, HDPE, PVC, and Glass Filled Polypropylene. Commonly available in natural color but their are manufacturers who accepts customized orders.

Metal pall ring

Among all pall rings made up of different materials, this metal pall ring is the one that is mechanically sturdy with high resistance to high temperature and fouling.

Polypropylene pall rings

This is the most common pall ring packing made up of plastic. It is also named pp pall rings. It can resist to more than 100 degrees celsius but has a lower thermal deformation temperature.

Ceramic pall rings

Ceramic pall rings has a strong resistance against alkali and high temperature.
