Metal Raschig Cross flow Grid structured packing:
Metal Raschig Cross flow Grid structured packing 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.

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 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.
