Corrufated packing is available in two main configurations: X and Y. In Y packings, the more common of the two, sheet align at a 45-degreee angle from horizontal. X packings, on the other hand, feature a 60-degree inclination, provide a lower pressure drop that makes then better suited for high-capacity applications.
It strengthens uniform liquid distribution and surface wetting ability, which increases mass transfer efficiency. The unit height is 50-200 mm per coil, and the packing is prepared in blocks when diameter is larger than 1.5 m.
It is formed from vertical sheets of corrugated metal with the angle of the corrugation reversed in adjacent sheets to form an open structure with inclined flow channel. Its structure can not only change the distribution of liquid, but also increase the transfer efficiency.
