WebA correlation has been developed for the Mellapak packing series. This model is quite different from other published models. It accounts for actual contributions of geometric parameters, and so it offers the possibility of identification of new packings based on changes to geometry that can reduce pressure drop or improve mass transfer. WebWell known and often used is the correlation of Fair [10] originally developed for sieve trays (Fig 4). A theoretically better founded approach has Figure 4. Correlation of the maximum gas load according to been developed by Stichlmair [4, 11].
