ABSTRACT:
A membrane separation and purification process, and the associated apparatus, provides separation of one membrane-permeable component from another, where both are contained in a multiple-component fluid mixture, as a dynamic function of the differences in respective rates of attainment of and declination from steady-state membrane permeation. The process and apparatus are equally well suited to multi-component fluid mixtures that are liquid or gaseous.
