Devices, systems, and methods for carbon capture optimization in industrial facilities are disclosed herein. An example carbon capture process involves cooling a flue gas stream using at least one gas-to-air heat exchanger disposed upstream of a carbon dioxide (CO2) absorber. Another example carbon capture process involves heating a heat medium for solvent regeneration and CO2 stripping using a fired heater and/or using at least one waste heat recovery unit.

The invention relates to a process for dehumidifying a moist gas mixture. The invention further relates to an apparatus for dehumidifying a moist gas mixture and to the use of said apparatus in the process according to the invention.

A method of treating a switchable polarity material comprises introducing a first feed stream comprising a solvent and a non-polar form of the switchable polarity material to a first side of a gas diffusion membrane. A second feed stream comprising an acid gas is introduced to a second side of the gas diffusion membrane opposing the first side of the gas diffusion membrane. Molecules of the acid gas of the second feed stream are diffused across the gas diffusion membrane and into the first feed stream to form a product stream comprising a polar form of the switchable polarity material. A treatment system for a switchable polarity material, and a method of liquid treatment are also described.

An ionic liquid desiccant system utilizes an ionic liquid desiccant to draw moisture from a working fluid, such as air that flow into an enclosure, such as a home. The desiccant may be mixed with the working fluid or a separator that allows moisture transport therethrough may be configured between the ionic liquid desiccant and the working fluid. The ionic liquid desiccant system may be part of an air conditioning system and may remove the moisture from air that is cooled by flowing over an evaporator or heat exchanger coupled with the evaporator. The ionic liquid desiccant may be pumped from a desiccant chamber to a regenerator chamber to remove absorbed moisture. A dual-purpose chamber may act as a desiccant chamber and as a regenerator chamber. A refrigeration system may have an electrochemical compressor and may utilize metal hydride heat exchangers.

Disclosed are systems and methods which provide a process stream comprising a gaseous component, capture the gaseous component from the process stream by an ionic liquid solvent of a separator, and recover a captured gaseous component from the ionic liquid solvent in a regenerator. A second gaseous component from the process stream may be captured by the ionic liquid solvent of the separator, and the second gaseous component may be recovered from the ionic liquid solvent in the regenerator. Alternatively, the second gaseous component from the process stream may be uncaptured by the ionic liquid solvent, and the uncaptured second gaseous component may be recovered from a membrane unit.

A system for absorbing and separating acid gases may include an absorbing tower in which a gas containing an acid gas is supplied, a recycling tower that is disposed close to the absorbing tower, an absorbent that absorbs an acid gas in the absorbing tower and discharges the acid gas back to the recycling tower while circulating through the absorbing tower and the recycling tower, and a condenser that is connected to the recycling tower and condenses an acid gas produced in the recycling tower, wherein a centrifugal separator that separates the absorbent, using a centrifugal force, is disposed at a lower portion in the absorbing tower.

A process and an apparatus for dehumidifying a moist gas mixture are provided. The apparatus for dehumidifying a moist gas mixture can be used and in the process. The absorption medium used in the process and the apparatus is also provided.

An environmental control system includes an air conditioning subsystem and a contaminant removal subsystem downstream of the environment to be conditioned. The contaminant removal subsystem includes: a first gas-liquid contactor-separator; a second gas-liquid contactor-separator; and a dehumidifier disposed either upstream of the first gas-liquid contactor-separator or downstream of the second gas-liquid contactor-separator.

A transformational energy efficient technology using ionic liquid (IL) to couple with monoethanolamine (MEA) for catalytic CO.sub.2 capture is disclosed. [EMmim.sup.+][NTF.sub.2.sup.−] based catalysts are rationally synthesized and used for CO.sub.2 capture with MEA. A catalytic CO.sub.2 capture mechanism is disclosed according to experimental and computational studies on the [EMmim.sup.+][NTF.sub.2.sup.−] for the reversible CO.sub.2 sorption and desorption.
