Ceramic Raschig Ring Product No.: KPK-CRR In the history of tower packing, raschig ring is the earliest annular packing with fixed geometry shape. It has the following characters: same outer diameter and height, simple structure and low price. But it has problems of asymmetry distribution of liquid and serious phenomena of wall flow and canal flow. Now we usually use corruption-resistant ceramic raschig ring in acid making industry. Application: Raschig Rings have a long history of improving separation efficiency in application including: 1. Petrochemical distillation and extraction application 2. Absorption in gas processing and combustion plants 3. Desorption in water treatment
