Numerical interpretation of a mathematical model of membrane gas separation with energy transfer by gas flowing in a channel to gas penetrating this channel from the adjacent channel
Maciej Szwast , Zbigniew Szwast
AbstractComparative calculations with a mathematical model designed by the authors, which takes into con- sideration energy transfer from gas flowing through a given channel to gas which penetrates this channel from an adjacent channel, as well as a model which omits this phenomenon, respectively, were made for the process of separating gas mixtures carried out with an inert sweep gas in the four- end capillary membrane module. Calculations were made for the process of biogas separation using a PMSP polymer membrane, relative to helium as the sweep gas. It was demonstrated that omitting the energy transfer in the mathematical model might lead to obtaining results which indicate that the capacity of the process expressed by the value of feed flux subjected to separation is by several percent higher than in reality.
