Description

Ceramic Pall Ring for Separating, Cooling and Absorbing


Pall rings were developed by BASF AG around 1940’s based on the raschig ring. They are still widely used in the industry owing to their good capacity characteristics at low- pressure drops. Punched windows on the outside facilitate better vapour flow and increase capacity as compared to raschig rings.
