ABSTRACT:
Membrane separation methods and systems separate gaseous mixtures into purified component gases thereof. Purified oxygen gas (60-90% purity), for example, may be derived from ambient air in an efficient manner. Systems and methods are provided by which at least three permeator stages are used while requiring less than one compressor per stage. Energy requirements are reduced and product purity as a function of energy requirements is improved.
