METHODS OF DETERMINING THE PERMEABILITY OF SELECTIVELY PERMEABLE MEMBRANES

An exact solution of the problem on the dynamics of separation of a gas mixture in membrane separators of different designs has been obtained. A procedure for interpreting the time dependence of the pressures on different sides of a selectively permeable membrane for determining the coeffi cients of its permeability is proposed. The direct and inverse problems on determination of the parameters of membrane separators were posed and solved. It was established that the accuracy of determining the permeability coeffi cients of a selectively permeable membrane depends on the duration of an experiment.
