Transport Phenomena in Membrane Separation Processes

Transport phenomena in ultrafiltration: membrane selectivity and boundary layer phenomena

Retention characteristics of UF membranes are de— lineated through comparison of the combined viscous flow and frictional model with the Ferry—Faxen equation. The molecular weight cut—off concept is discussed using calculations of how sharp cut-off curves one can expect of UF membranes with uniform pore sizes and how heteroporosity will affect such curves. Experimental retention—flux curves for...

Engineering of Membrane Gas Separation Processes: State of The Art and Prospects

Membrane processes are today one of the key technologies for industrial gas separations and show growing interest for future use in sustainable production systems. Besides materials development, dedicated engineering methods are of major importance for the rigorous and most efficient design of membrane units and systems. Starting from approaches based on simplified hypotheses developed in the 5...

Integration of Gas Transport through a Composite Catalytic Inorganic Ceramic Membrane for Environmental Gas Separation Processes

This work presents the transport behaviour of carrier gases with inorganic ceramic membrane used for environmental gas separations at 289K and 0.01-1 bar. The gases tested include: Helium (He), Nitrogen (N2) Carbon dioxide (CO2) and Argon (Ar). The Knudsen ideal selectivity ratio of 0.95, 0.3 and 0.79 for Ar/CO2, He/CO2 and N2/CO2 gas respectively was slightly higher than the theoretical select...
