Abstract
Significant effort has been devoted to the study of mass transfer in sheet metal structured packings over the past half century. A number of mass transfer correlations have appeared in the literature as a result of those efforts. Unfortunately, none of these correlations has shown itself to be reliable over the full range of chemical systems, column operating conditions, and packing topologies encountered today. In an attempt to rectify some of the shortcomings of earlier correlations for sheet metal structured packings, we have employed a new data analysis methodology which simultaneously fits ⟨HETP⟩ data and mass transfer area data. The correlation we report upon here includes 444 ⟨HETP⟩ values from a variety of systems, operating pressures, and packing designs, along with 409 mass transfer area measurements. We demonstrate that this correlation outperforms all others while remaining simple enough to implement in process simulation software.
