1. An apparatus for the separation and optional recovery of CO2 from a gas stream, by a cyclic adsorption/desorption process using a loose particulate sorbent for gas adsorption; wherein the apparatus comprises:
a sealable enclosure having an inlet for a gas stream and an outlet for a purified gas stream on axially opposite sides, and a vacuum chamber featuring the inlet for a gas stream and the outlet for a purified gas stream on axially opposite sides, the sealable enclosure further comprising:
one or more stacks of cartridges wherein each stack has a plurality of adjacent, parallel, spaced-apart cartridges,
wherein each cartridge extending axially in the sealable enclosure parallel to the gas stream through the sealable enclosure between the inlet and outlet and forming a serpentine flow path for the gas stream through said sealable enclosure, and wherein each cartridge has a gas permeable fabric enclosure mounted on a frame and forming a cavity within the frame for the loose particulate sorbent, wherein each frame has two frame members,
wherein the vacuum chamber comprises
(1) pairs of axially-extending first and second baffles, provided adjacent to, and on laterally opposite sides of, each of the inlet and the outlet of the vacuum chamber,
wherein the pair of first baffles direct movement of an initial gas stream from the inlet toward the outlet and also direct movement of a gas stream, from which a CO2 gaseous component has been partially removed, laterally away from the inlet and
wherein the pair of second baffles direct movement of a final gas stream, from which the CO2 gaseous component has been removed, toward the outlet and also prevent movement of gas, from which the CO2 gaseous component has been partially removed, laterally toward, and outward of, the outlet, and
(2) one or more laterally- and vertically-extending third and fourth baffles provided between the inlet and the outlet,
wherein the third and fourth baffles direct movement of gas, from which the CO2 gaseous component has been partially removed, laterally away from the inlet in opposite lateral directions and laterally toward the outlet in opposite lateral directions, and
wherein the pairs of first and second baffles, and the third and fourth baffles extend vertically from a bottom wall to a top wall of the vacuum chamber and provide a serpentine flow channel for movement of gas through the vacuum chamber.
