文摘
- •
A detailed model for gas permeation through asymmetric membranes is presented.
- •
The Joule-Thomson effect gives very small transmembrane temperature drops.
- •
The accumulated Joule-Thomson effect can be significant along the membrane unit.
- •
Nonequilibrium coupling effects can enhance both permeability and selectivity.
- •
The support layer currently limits the possibility of exploiting of coupling effects.
