Ceramic Pall Ring is improved from the ceramic Raschig Ring, Ceramic Pall Ring has add a design of open the holes for the weeks wall, this construction can improve the surface area and voidage, Ceramic Pall Ring makes porosity distributed even and improves the distribution of the fluid, greater capacity and lower pressure drop than ceramic rasching ring.
Ceramic Pall Ring with excellent acid resistance and heat resistance. They can resist to corrosion of various inorganic acids, organic acids and organic solvents except hy-drofluoric acid, and can be used in high or low temperature conditions. Consequently their application ranges are very wide. Ceramic Pall Ring can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.
