Pall Ring 

1. Pall Ring Introduction

Pall ring is an advanced improvement of rasching ring, the walls of pall ring is open, height and diameter are the same and it has 4 diametrical ribs towards the inside of each "floor". Its structure improves distribution of gas-liquid and its efficiency can be improved above 50% and only has half of pressure drop compared with rasching ring.

2. Pall Ring Advantages

2.1. Low pressure drop

2.2. Low mass-transfer unit height 

2.3. High flooding point

2.4. Small specific gravity 

2.5. Uniform gas-liquid contact 

3. Pall Ring Application

It can be applied to various of device of isolation, absorption,deadsorption,common decompression such as Toluene separation ,ethylbenzene separation, isooctane separation and desulfurization System etc..
