A general approach to modelling membrane modules
James Marriott,Eva Sorensen +1 more
TLDR
In this paper, mathematical models of hollow-fibre and spiral-wound membrane modules were developed from rigorous mass, momentum and energy balances and can be used to describe a generic membrane separation, in contrast to most existing models which are typically process specific and are only valid within a limited operating range.About:

Viscous flow relative to arrays of cylinders
TL;DR: In this paper, the free-surface model was extended to the case of flow relative to cylinders and shown to be in good agreement with existing data on beds of fibers of various types and flow through bundles of heat-exchanger tubes.

Mass transfer and pressure loss in spiral wound modules
G. Schock,A. Miquel +1 more
TL;DR: In this paper, the authors present some experimental data for pressure drop and mass transfer characteristics in spiral wound elements and in spacer-filled flow channels and the experimental results and the computer program were used to calculate the performance of a spiral wound element and its possible design variations.

Modeling permeation of binary mixtures through zeolite membranes
TL;DR: In this paper, the authors used the empirical Vignes relation for the prediction of the binary Maxwell-Stefan surface diffusivity, and showed that the importance of incorporation of adsorbate-adsorbate interactions in the model is clearly shown, both for transient and steady-state mixture permeation.

Gas separation by high‐flux, asymmetric hollow‐fiber membrane
TL;DR: A mathematical model of multicomponent permeation systems with high-flux, asymmetric hollow-fiber membranes is presented in this paper, which takes into account the permeate pressure variation inside the fiber.
