1. A species transfer system for transferring at least one species from an inlet stream having a first concentration of the species, to a controlled species outlet stream, comprising:

  • an absorber assembly having an inlet for the inlet stream and an outlet for a lean species stream having a second concentration of the species being lower than the first concentration of the species of the inlet stream;

    sorbent located in the absorber assembly to capture at least a portion of the species from the inlet stream, and becoming at least partially spent sorbent upon species capture;

    a regeneration assembly having an inlet, and an outlet for the controlled species outlet stream; and

    the at least partially spent sorbent located in the regeneration assembly releasing at least a portion of the captured species from the absorber assembly to the controlled species outlet stream;

    wherein the species transfer system can effectively handle an inlet stream flow rate of at least approximately 11,500 ft3/sec; and

    wherein the species transfer system provides 90% species capture, such that the lean species stream has less than approximately 10% of the species concentration of the inlet stream.
