Ceramic Pall ring is an advanced improvement of rasching ring, the walls of pall ring is open, height and diameter are the same and it has 4 diametrical ribs towards the inside of each "floor". Its structure improves distribution of gas-liquid and its efficiency can be improved above 50% and only has half of pressure drop compared with rasching ring.
Ceramic pall ring has excellent acid resistance and heat resistance. 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.
