Abstract
A process and/or system for processing a pressurized gas mixture by membrane separation. Portions of the pressurized gas mixture are withdrawn and provided as a plurality of pressurized gas streams at successively lower pressures. Each portion, provided as a respective pressurized gas stream, is provided for processing in a respective membrane system, each of which is at a different pressure level. Partially purified streams produced by one or more membrane systems are provided for processing at lower pressure levels (e.g., where they are combined with one of the pressurized gas streams). Accordingly, costs associated with recycle compression are reduced and/or eliminated.
