Plastic Raschig Ring
Plastic Raschig Ring
NAIKE Plastic Raschig rings are pieces of the tube (approximately equal in length and diameter) used in large numbers as a packed bed within columns for Distillations and other chemical engineering processes. It provides a large surface area within the volume of the column for interaction between liquid and gas or vapour. Raschig rings are named after their inventor, the German chemist Friedrich Raschig.
