1. A regeneration system, comprising:
- a first regeneration module containing a first chosen regenerative substance;
a second regeneration module containing the first chosen regenerative substance; and
a first mixing chamber, wherein a first outlet stream of a fluid sequentially exits the first mixing chamber, flows through the first regeneration module in fluid communication with the first chosen regenerative substance and returns to the first mixing chamber, and a second outlet stream of the fluid sequentially exits the first mixing chamber and flows through the second regeneration module in fluid communication with the first chosen regenerative substance.

Abstract
A regeneration system that has a first regeneration module containing a first chosen regenerative substance; a second regeneration module containing the first chosen regenerative substance; and a first mixing chamber. A first outlet stream of a fluid sequentially exits the first mixing chamber, flows through the first regeneration module in fluid communication with the first chosen regenerative substance and returns to the first mixing chamber, and a second outlet stream of the fluid sequentially exits the first mixing chamber and flows through the second regeneration module in fluid communication with the first chosen regenerative substance.

39. A method of regenerating a fluid, comprising the steps of:
-
conveying a first outlet stream of the fluid from a first mixing chamber to a first regeneration module containing a first chosen regenerative substance; removing a waste species from the first outlet stream in fluid communication with the regenerative substance; returning the first outlet stream to the first mixing chamber; mixing a first inlet stream of the fluid entering the first mixing chamber with the first outlet stream returned to the first mixing chamber; conveying a second outlet stream of the fluid from the first mixing chamber to a second regeneration module containing the first chosen regenerative substance; and removing the waste species from the second outlet stream in fluid communication with the regenerative substance. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47)
