Kinetic Efficiency Factors for Facilitated Transport Membranes |
| |
Abstract: | Abstract A kinetic efficiency factor (η) is defined for facilitated transport membranes. η is defined as the actual facilitated flux divided by the facilitated flux under reaction equilibrium conditions. η is correlated with an inverse Damkohler number ε. A dimensionless equilibrium constant K and mobility ratio a also affect the value of η. η is shown to be useful in determining the operating regime of the system, comparing actual performance to maximum attainable, and providing a qualitative measure of the time to reach steady-state conditions. |
