Product Description

Plastic Raschig pak:
Plastic Raschig Pak is  manufactured by welding profile-shaped plastic foils onto each other. Two aspects are important:

Even liquid distribution from the structure of the whole packingThe profile-shaped foils as well as the structure reached by the inclination of the foils towards each other (channel inclination) achieve an even liquid distribution throughout the packing for low up to very high liquid loads.
High rate of mass transfer by profile-shaped foilsThe wave-like profiles (inner structure) of the single foils assure a continuous thorough mixing of gas and liquid. This constant renewal of the gas/liquid boundary results in high mass transfer rates.

Detailed Photos

To compared with Metal Structured packing, the advantage as follows:
1:the cost of a packing in plastics is substantially lower than for one in stainless steel. Plastics packing also has lower weight, which reduces transport and mounting costs. 
2: Injection Type structured packing an extend the lifetime of the solvents, thereby reducing the operation costs. Plastics packing
3:Plastic structured packing intensive texture achieves a high effective surface area and form liquid bilm to improve CO2 capture.

Installation Instructions

1:According to the tower equipment diagram,and make sure that packing installation heights is correct.
2:When installing, it should always be poured from a certain height away from the packing layer. People should not stand directly on the packing to prevent the packing from deformation and uneven density. Wooden boards can be laid on the packing to disperse the force.
3:Other sundries, packaging bags, etc. is forbidden during the installation
4:Generally filled by random packing
5:After finished, if there is unevenness, use a wooden strip to naturally push it flat

 

 

 

Application

Application fields:
The packing is widely used in absorption and desorption unit operation. It is especially suitable for those processes with high liquid loading and high operation pressure, e.g. hydrochloric acid and sulfuric acid industry, stripping of CO2 and H2S in natural gas, chlorine gas drying, ammonia preparation, purification treatment of waste gases and desorption apparatus.
