Type: 100, 150, 250, 350, 400, 450, 500, 550, 700, 1000 etc
Advantage
● High capacity. New tower design may reduce diameter, while renovate old towers may increase capacity significantly.
● High separation efficiency. Since it has much larger specific surface area compared to random packing.
● Low pressure drop, which leads to reduce energy consumption largely.
● Large flexibility, and scale effect is not obvious.
● Suitable for all tower diameters.
● Strong resistance to corrosion of acid and alkali, especially to H2S, naphthenic acid and Cl- .

Applications
● Rectifying organic halide.
● Rectifying and absorbing some corrosive mixtures, which are definitely regulated in pressure drop and theoretic plate number.
● Applied in some towers that contain a large quantity of natural media used to absorb nitric acid and concentrated sulfuric acid, as well as for purifying the air in chemical plants.
● Operating in vacuum conditions at a bottom absolute pressure of 100pa.
● Used in heat exchanger and demisting, or as a catalyst carrier.
