The role of the Pall ring

- Sep 18, 2019-

The Pall ring packing is a small rectangular window with two layers on the wall of the ordinary Raschig ring. The small window leaves are placed at the center of the ring, and the upper and lower windows are staggered. Therefore, the resistance is reduced and the gas velocity can be increased. Under the same pressure drop, Uniform liquid phase distribution, processing capacity can be increased by 50% than Raschig ring

The Pall ring packing has the characteristics of low pressure drop, large flux and high efficiency. It is also widely used and can be used in many chemical project installations. It has a lower pressure drop and higher mass transfer efficiency, and the liquid distribution in the packing layer is good.
