Description

Ceramic Raschig Ring for Drying Tower 


Raschig rings are pieces of tube, approximately equal in length and diameter, used in large numbers as a packed bed within columns for distillations and other chemical engineering processes. They are usually ceramic or metal and provide a large surface area within the volume of the column for interaction between liquid and gas vapours. Raschig rings are named after their inventor, the German chemist Friedrich Raschig.
