Abstract
The present invention is directed to a method and a system for separating hydrogen or helium from gas having a mixture of gaseous components. A compressible feed stream that contains at least one target compressible component and hydrogen or helium is mixed in a substantially co-current flow with an incompressible fluid stream comprising an incompressible fluid in which the target component(s) is/are capable of being preferentially absorbed. Rotational velocity is imparted to the mixed streams, separating an incompressible fluid in which at least a portion of the target component is absorbed from a compressible product stream containing the hydrogen or helium. The compressible feed stream may be provided at a stream velocity having a Mach number of at least 0.1.
