Unique Structure
Point contact appears between plastic conjugate rings and between the packing and the column wall. Meanwhile, the void is uniform. The plastic packing comes with low fluid resistance (i.e. low pressure drop) and high capacity. When fluids pass through the packing bed, liquid contacts gas well and the tendency of channeling and wall flowing is small, which results in excellent mass transfer effect.
Features
The plastic conjugate ring, a kind of plastic random packing, comes with advantages like high void ratio, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific weight, high mass transfer efficiency, and so on.
Application
The plastic conjugate ring is used in the packing towers in the petroleum, chemical, alkali-chloride, coal gas and environmental protection industries. To illustrate, it can be used in alcohol purification, sulfuric acid absorption, rectification for methyl methacrylate, oleum refinement, waste gas cleanse, water decontamination, etc.
To suit customers' varied demands, we offer plastic conjugate rings made of varied heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chloridized polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF).
