Claim 0:
1. An apparatus for separating a gas mixture having at least two components, comprising:
a plurality of membrane separation stages including a first membrane stage, a second membrane stage, and a third membrane stage;
the first membrane stage designed to separate the gas mixture into a first retentate stream and a first permeate stream;
the second membrane stage designed to separate the first permeate stream into a second retentate stream and a second permeate stream;
the third membrane stage designed to separate the second retentate stream into a third retentate stream and a third permeate stream;
a continuing stream that places the first retentate stream in fluid communication with the second retentate stream;
a first gas transport device with a first inlet in fluid communication with the gas mixture and a first outlet in fluid communication with the first membrane stage;
a second gas transport device with a second inlet in fluid communication with the first retentate stream and a second outlet in communication with the continuing stream; and
a controller in communication with at least one measuring device and the first gas transport device;
wherein the at least one measuring device is designed to measure at least one parameter of the gas mixture, the first permeate stream, the second retentate stream, or the third retentate stream, and wherein the controller adapts a behavior of the first gas transport device in response to a change of the at least one parameter of the gas mixture, the first permeate stream, the second retentate stream, or the third retentate stream as measured by the at least one measuring device,
wherein the second gas transport device is in communication with the controller, and wherein the controller adapts the behavior of the second gas transport device in response to a measurement of the at least one parameter by the at least one measuring device.
