1.high void ratio 2. low pressure drop 3.sufficient gas liquid contact 4.small specific weight
Product parameters:
Pall ring is an economical and versatile. The characteristic as follows :♦Good Capacity and Low Pressure Drop; Higher capacity and lower pressure drop than ceramic packing Multiple sizes provide ability to optimize capacity and efficiency based on application requirement . ♦ Higher Liquid Hold-up and Residence Time: Relatively high liquid hold-up allows good absorption efficiency with slow chemical reaction. ♦ Versatile Standard Packing: Lower sensitivity to liquid and vapor distribution quality allows use with conventional liquid distributors. ♦ High Mechanical Strength: Ring and spoke construction provides high mechanical strength, and allows to be used in deep beds Application Absorption, Scrubbing, and stripping service. Alternative to metal Pall rings.
