Abstract: Economical processes of the present invention are for separation of fluid mixtures to recover desired products using apparatus comprising a plurality of membrane modules disposed in a first product group, a second product group, and optionally one or more intermediate group. Advantageously integrated processes of the invention with the membrane modules in multiple groups are employed for simultaneous recovery of a very pure permeate product and a desired non-permeate product from a mixture containing organic compounds.
