Modular true moving bed apparatus for gas separation and method of same

A modular true moving bed apparatus for gas separation 100, comprising:

• a static gas-tight enclosure 102;
• a locomotion means 104;
• a plurality of carriages (106a,106b, . . . , 106n) capable of traversing via the locomotion means 104, wherein each of the plurality of carriages comprises a front end having an inlet one-way valve, and a rear end having an outlet one-way valve, and each of the plurality of carriages carries a sorbent material, wherein the locomotion means 104 provides a mechanism to adjust a distance between two consecutive carriages from among the plurality of carriages while in motion;
• and
• a plurality of zones comprising an adsorption zone 108 and a desorption zone 110, connected in series in a closed loop, wherein the plurality of carriages (106a,106b, . . . ,106n) traverse through the plurality of zones, and each of the plurality of zones comprises at least one inlet port to feed a gaseous mixture and at least one outlet port to exit raffinate,
• wherein each of the plurality of carriages (106a,106b, . . . ,106n) carrying the sorbent material traverses via the locomotion means through each zone during the gas separation process,
• wherein the adsorption zone 108 receives a gaseous mixture from at least one of the inlet port, and each of the plurality of carriages (106a,106b, . . . ,106n) carrying the sorbent material adsorbs a target gas from the gaseous mixture while traversing via the locomotion means 104,
• wherein the desorption zone 110 desorbs the target gas from the sorbent material present inside each of the plurality of carriages (106a,106b, . . . , 106n), and
• wherein a sealing mechanism seals the inlet one-way valve and the outlet one-way valve of each of the plurality of carriages carrying the sorbent material to prevent leakage in the adjoining zones.
