Influence of the Multilayer Nature of a Composite Membrane on Mass Transfer
RÉSUMÉ
The significance of separate characterization of every single layer in a composite ceramic membrane has been investigated. It is shown that each layer of composite membrane must be characterized independently, and ignoring the effects of multilayer nature of the composite membrane can be misleading for the quantification of mass transfer. The dusty gas model for single gas permeation was used to study these effects. Single gas permeation experiments were conducted for three different gases (air, nitrogen, and helium) at various temperatures (25−500° C) and pressure conditions (1−3 bar). It is obvious from analysis that each layer of the composite membrane must be characterized separately and the transport parameters of each membrane layer must be taken into consideration while quantifying the mass transfer through composite membranes.
