Porcelain Raschig Rings Description
Porcelain Raschig Rings are common regular packing that is still used for refilling existing columns and other applications. Its surface ratio is higher than ceramic cylinders and balls by 30% and its ring shape has high mechanical stability. It has excellent acid resistance and heat resistance. The mass transfer of ceramic Raschig Ring is low, but it is much cheaper than the other random packing, so it is still widely accepted in some industries.

Porcelain Raschig Rings Applications
Porcelain Raschig Rings are ceramic cylindrical packing materials used in chemical and petrochemical industries for mass transfer operations. They are commonly employed in packed bed columns for gas-liquid or liquid-liquid contact, providing increased surface area for improved separation, absorption, and distillation processes.
Porcelain Raschig Rings are widely used in towers in chemical, petrochemical, and metallurgical industries, such as drying towers, absorbing towers, cooling towers, etc.
