Pall ring is made from heat resistant and chemical corrosion resistant plastic , for instance.Polypropylene (pp). An advance on the raschig ring, the pall ring has similar cylindrical dimensions but has two rows of punched out holes, with fingers or webs turned into the centre of the cylinder, which significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop.
It is widely apply in the separation and absorption process, device of reducing pressure. The system of deviating sulfur. Isolation of ethyl benzene. Toluene, trimethylpentane, absorbers, degassing, liquid/liquid extraction, water treatment, heat transfer, etc.
