Ceramic Raschig ring is the earliest generation of random packing with excellent acid resistance and heat resistance. They 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. The height is equal to the diameter. And the normal specifications are 25mm to 76mm. Though the mass transfer of ceramic raschig ring is low, it is much cheaper than other random packing, so it is still widely accepted.
Acid and alkali resistance
Excellent heat resistance
High specific surface area and low cost
High mechanical strength
Energy saving, low operation cost and easy to be load and unload
Ceramic Raschig rings are a highly effective and low-cost material to pack your column with and they can be widely used in the drying tower, absorption tower, cooling tower and washing towers in chemical, metallurgy, coal gas, industrial oxygen production industries.
