Abstract
A target chemical species, such as carbon dioxide, may be separated from a mixed gas by passing at least a portion of the mixed gas from a first chamber through a gas-selective membrane and into a second chamber, producing a concentrated gas. The concentrated gas has a higher concentration of the target chemical species than the mixed gas. At least a portion of the concentrated gas is passed through a diffusion-based membrane to a third chamber, where the third chamber includes an absorbent liquid in contact with one side of the diffusion-based membrane. The target chemical species is at least partially dissolved in the absorbent liquid and passed out of the system.
