Plastic Pall Ring Tower Packing

1.high void ratio 2.low pressure drop 3.sufficient gas liquid contact 4.small specific weight

Features and application

Pall ring is made of standing up to chemical corrosion materials, such as polyethylene(PE), polypropylene (PP),reinforced polypropylene(RPP),polyvinyl chloride(PVC), chlorides polyvinyl chloride(CPVC) and polyvinylidene fluoride(PVDF). It has feature such as high void ratio, low pressure drop, sufficient gas liquid contact, small specific weight, high mass transferring efficiency and so on. The operation temperature is 60-150°C. It is widely used in petroleum, chemical, alkali-chloride, coal gas and environment protection, etc.
