ASSESSMENT OF DIFFUSION COUPLING EFFECTS IN MEMBRANE SEPARATION .1. NETWORK THERMODYNAMICS MODELING

Network thermodynamics and bond graph theory have been used in modelli ng of coupled diffusion in a mixture of two components permeating thro ugh a membrane. The possibility of evaluating the degree of coupling f rom the steady-state measurements has been shown, as well as the influ ence of coupling on separation properties of the system. The results m ay be utilized to properly set up separation experiments in order to a chieve the maximum possible separation in an experimental system.
