Ceramic Raschig Ring

Specific Application:

Used in the drying columns, absorbing columns, cooling towers, scrubbing towers and actifier columns in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc. 


Summary:

Ceramic Raschig Ring 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 provide a large surface area within the volume of the column for interaction between liquid and gas vapours.
