Wire gauze packings have been successfully used in industry about thirty years. The largest column diameter is up to 6 meters. They are made of wire gauze. The normal types are TJS500 and TJS700.
Very high number of theoretical stages per meter
Pressure drop per theoretical stage 0.01~0.06kpa
Minimum liquid load 0.2m3/m2Ěh
For large number of theoretical stages where minimum pressure drop is also important
In vacuum from 0.1kpa to atmospheric pressure
For small overall height
For batch and continuous columns
Pilot columns (confident scale-up)
Limited suitability or unsuitable for:
Fouling substances that form deposits
Strongly corrosive media
Not recommended for very large diameter columns and high-pressure distillation columns
Feature curves of TJS500 and TJS700 are listed below.
