Centrifugal force gas separation with an incompressible fluid

A system comprising:

• a compressible fluid separation device that
• 1) receives
• a) an incompressible fluid stream comprising an incompressible fluid;
• and
• b) a compressible feed stream comprising a first compressible component and a second compressible component;
• and
• 2) separates the compressible feed stream into a first compressible product stream comprising at least 60% of the second compressible component and an incompressible fluid product stream comprising at least 60% of the first compressible component;
• an incompressible fluid regenerator that receives the incompressible fluid product stream and discharges a second compressible product stream comprising the first compressible component and a first compressible component-depleted incompressible fluid product stream;
• and
• an incompressible fluid injection device that receives the first compressible component-depleted incompressible fluid product stream and mixes the first compressible component-depleted incompressible fluid product stream with the compressible feed stream.

A method comprising:

• providing a compressible feed stream comprising a first compressible component and a second compressible component;
• selecting an incompressible fluid and providing an incompressible fluid stream comprising the incompressible fluid, wherein the incompressible fluid is selected to selectively absorb the first compressible component relative to the second compressible component;
• mixing the compressible feed stream and the incompressible fluid stream in a substantially co-current flow to form a mixed stream having an instantaneous linear velocity;
• imparting a rotational velocity to the mixed stream in a direction tangential or skew to the direction of the instantaneous linear velocity of the mixed stream;
• and
• separating an incompressible fluid product stream from a first compressible product stream, where the incompressible fluid product stream comprises an increased amount of the first compressible component relative to the incompressible fluid stream and the first compressible product stream comprises a reduced amount of the first compressible component relative to the compressible feed stream, and where the incompressible fluid product stream is separated from the first compressible product stream by the rotational velocity imparted to the mixed stream.
