Chemical engineering contributions resulting in an improved understanding of the Stefan diffusion column: A 150-year perspective

A steady two‐dimensional cylindrical mass transport model to determine binary gas diffusivities: A proof‐of‐concept theoretical development

“…Quantification of these end effects and their relationship to the estimated diffusivities have been attempted in several studies with various levels of success, and the reader is referred to a recent review article by Ramírez for an updated and comprehensive coverage of the subject. [23] As part of our research program on Stefan column operation and D AB estimation, we have addressed issues such as thermal effects, [24] sweep stream Reynolds number, [25] multicomponent liquid phases, [26][27][28] and curvature effects at the liquid-gas interface. [29,30] A better understanding of transport phenomena in the Stefan diffusion column has certainly emerged from these efforts.…”
