Knitmesh-column Packing Pads

These Knitmesh-Column Packing Pads are available with following salient features :
Low value of hetp [height equivalent of theoretical plate].
Typical values range from 100 to 150 mm. Low values of pdts [pressure drop per theoretical stage].
Typical values range from 0.04 to 0.05 mm of hg, depending upon the vapour load.
High vapour handling capacity: vapour handling capacity of knit mesh is comparable to 25 mm metal pall rings.
No reduction in efficiency even at low liquid irrigation rates: capillary action of knit mesh helps it to achieve uniform wetting of the entire package even at low liquid loadings. Packing can work without loss of efficiency at a liquid irrigation rate as low as 0.3 mh [0.5 gpm/ft]
Performance is independent of packing size: unlike random packings, the properties of knit mesh are independent of packing size. Hence its performance characteristics such as hetp and pdts are practically independent of packing diameter.
