Structured ceramic corrugated board packing
Unique structureA very thin liquid film can be formed on the ceramic surface. Turbulence of the liquid film and the oblique winding gas channel can promote vapor instead of stopping it, therefore separation efficiency of the packing is equal to that of metal corrugated-sheet packing. Surface structure of the ceramic packing has good wetting ability, which promotes liquid flow and minimizes liquid holdup, as a result, the opportunity of superheating, polymerization and coking reduces.
Excellent performancea) High capacity. New tower design may reduce diameter, while revamping old towers may increase capacity significantly.b) High separation efficiency owing to much larger specific surface area compared with random packing.c) Low pressure drop, which leads to reduce energy consumption largely.d) Large flexibility, and scale effect is not obvious.e) Applicable to all tower diameters.f) Strong resistance to corrosion of acid and alkali, especially to H2S, naphthenic acid and Cl-.
