A CO.sub.2 recovery method includes: heating a CO.sub.2-absorbing solution that has absorbed CO.sub.2 from a gas, releasing the CO.sub.2 from the CO.sub.2-absorbing solution, and regenerating the CO.sub.2-absorbing solution, and at least one of: controlling a difference between an actual measured value and a target value of a recovery rate of the CO.sub.2 to be within a predetermined range; and controlling a difference between an actual measured value and a target value of a recovery amount of CO.sub.2 to be within a predetermined range, and controlling the CO.sub.2 recovery rate through a proportional calculation and an integration calculation based on the difference between the actual measured value and the target value of the CO.sub.2 recovery rate.

In accordance with an embodiment, a carbon dioxide capturing apparatus includes a first absorbing unit, a regeneration unit, a water washing capturing unit, and a pre-amine capturing unit. The first absorbing unit brings a gas containing carbon dioxide into contact with an absorbing liquid containing an amine compound, and discharges the absorbing liquid which has absorbed carbon dioxide as a rich liquid. The regeneration unit releases a carbon dioxide gas from the rich liquid sent from the first absorbing unit. The water washing capturing unit captures the amine compound entrained in a decarbonated treatment gas sent from the first absorbing unit. The pre-amine capturing unit receives part of the rich liquid from the first absorbing unit, and traps the amine compound entrained in the decarbonated treatment gas by bringing the decarbonated treatment gas from the first absorbing unit into countercurrent contact with the part of the rich liquid.

Various embodiments of a portable carbon dioxide (CO2) absorption device that may remove excess CO2 from a closed environment are disclosed herein. The absorption device is reusable and configured for many environments.

Present disclosure discloses a system for separating hydrogen from feed gas. The system includes at least one compressor adapted to pressurize the feed gas to predefined pressure. One or more adsorber columns are fluidly coupled to the compressor and are adapted to receive the pressurized feed gas, where the adsorber columns include a body and an adsorber bed, which is disposed within the body.
