1. Description
Ceramic Pall Ring is a kind of new type and high efficient packing that is improved on the basis of the Rasching ring.  Chemshun pall ring is a proven design that provides higher capacity and lower pressure drop than trays and other random packings. The opened cylinder walls and inward bent protrusions of the Pall Ring allow greater capacity and lower pressure drop than standard cylindrical rings. This open ring design also maintains an even distribution and resists wall-channeling tendencies. The interior and exterior contacting surfaces of the Pall ring provide for an effective distribution of liquids and gasses and resist plugging, fouling and nesting.

2. Applicant:

Ceramic pall ring has good acid- and heat-resistant It can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions Consequently the application range is very wide The packing can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers and actifier columns in chemical, metallurgy, coal gas and oxygen producing industry.
