Abstract: A gas separation system has system input inlet configured to receive a stream mixture including a target gas, one or more spray generators positioned to spray a non-sprayable liquid to change a concentration of the target gas in the non-sprayable liquid, one or more system outlets positioned to outlet an output material, wherein at least one of the system outlets outputs a material having a lower amount of the target gas than the input stream mixture, and a recirculating path connected to the one or more outputs and the input inlet to allow recirculation of the non-sprayable liquid. A method of performing gas separation includes absorbing a target gas from an input stream in a non-sprayable capture liquid, and releasing the target gas in an output gas stream by spraying the non-sprayable capture liquid into a heated volume using a spray generator. A method of performing gas separation includes receiving an input stream that includes a target gas, using one or more spray generators to apply a non-sprayable liquid as a spray to the input stream to change a concentration of the target gas in the liquid, and outputting the liquid with the changed concentration through an outlet.

Abstract: A gas treatment device uses a gas to be treated which contains an acid compound that dissolves into water to produce acid and a treatment liquid which absorbs the acid compound to phase-separate, to separate an acid compound from the gas to be treated. The gas treatment device includes an absorber which brings the gas to be treated into contact with the treatment liquid; a regenerator 14 which heats the treatment liquid contacting the gas to be treated to separate an acid compound; and a liquid feeding portion which feeds the treatment liquid contacting the gas to be treated in the absorber to the regenerator. In the absorber, the treatment liquid contacting the gas to be treated phase-separates into a first phase portion having a high acid compound content and a second phase portion having a low acid compound content. The liquid feeding portion is configured to introduce, into the regenerator, the treatment liquid with the phase-separated first phase portion and second phase portion mixed.

Abstract: Methods of reducing the water content of a wet gas are presented. In one case, the method includes exposing the gas to an amine-terminated branched polymer solvent to remove a substantial portion of the water from the wet gas, exposing the diluted solvent to carbon dioxide to phase separate the solvent from the water, and regenerating the solvent for reuse by desorbing the carbon dioxide by the application of heat. In another case, the method includes exposing the gas to a cloud-point glycol solvent to remove a substantial portion of the water from the wet gas, heating the diluted solvent to above a cloud point temperature for the solvent so as to create a phase separation of the solvent from the water so as to regenerate the solvent for reuse, and directing the regenerated solvent to a new supply of wet gas for water reduction.

Abstract: The present disclosure provides improved systems, assemblies and methods to remove and recover CO2 from emissions. More particularly, the present disclosure provides improved membrane contactors configured to remove CO2 from flue gas by temperature swing absorption. In exemplary embodiments, the present disclosure provides a novel hollow fiber membrane contactor that integrates absorption and stripping using a nonvolatile reactive absorbent (e.g., 80% polyamidoamine (PAMAM) dendrimer generation 0, and 20% of an ionic liquid (IL)). Equilibrium CO2 absorption in the nonvolatile viscous mixed absorbent is as high as 6.37 mmolCO2/g absorbent in the presence of moisture at 50° C. A novel membrane contactor is provided for CO2 absorption and stripping via a process identified as temperature swing membrane absorption (TSMAB). The contactor integrates non-dispersive gas absorption and hot water-based CO2 stripping in one device/assembly containing two sets of commingled hollow fibers.
