Ceramic Pall Ring for Separating, Cooling and Absorbing

Five ceramic pall ring with different sizes on the gray background.
CPR-01: Ceramic pall ring has high separating efficiency.

Ceramic pall ring is a type of classical random packing, which is developed from the Raschig ring. Commonly, there are two layers of windows opened along its cylinder wall. Each layer has five ligules bending inward the axes of the ring, which is similar to the metallic pall ring and plastic. But the layer and quantity of ligules may different according to the height and diameter variation.

Generally, the opening area occupies 30% of the total area of the cylinder wall. This design helps vapor and liquid flow freely through these windows, making full use of the inner surface of the ring to improve the distribution of vapor and liquid. It can also improve the separating efficiency.
