TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Process: In the process, treating operative carbon dioxide supply-comprising gaseous material feed includes effecting separation from a separation process feed material of carbon dioxide-rich separation fraction, where the separation process feed material is defined by at least a fraction of the operative carbon dioxide supply-comprising gaseous material feed, where the carbon dioxide-rich product material includes the carbon dioxide-rich separation fraction. The ratio of moles of carbon dioxide within the carbon dioxide-rich separation fraction to moles of at least one other material of the separation process feed material within the carbon dioxide-rich separation fraction is greater than the ratio of moles of carbon dioxide within the separation process feed material to moles of at least one other material of the separation process feed material within the separation process feed material. The method of effecting separation from a separation process feed material of carbon dioxide-rich separation fraction includes: effecting dissolution of at least a fraction of the carbon dioxide of the separation process feed material so as to effect production of a carbon dioxide-comprising liquid solution product including dissolved carbon dioxide; effecting release of a gaseous carbon dioxide-rich intermediate from carbon dioxide-comprising liquid solution product feed such that a carbon dioxide-comprising mixture is provided including the gaseous carbon dioxide-rich intermediate, where the carbon dioxide-comprising liquid solution feed includes at least a fraction of the carbon dioxide-comprising liquid solution product, and the gaseous carbon dioxide-rich intermediate includes at least a fraction of the dissolved carbon dioxide of the carbon dioxide-comprising liquid solution product; and separating a gaseous carbon dioxide-rich recovery product from the gaseous carbon dioxide-rich intermediate, where the carbon dioxide separation fraction includes at least a fraction of the gaseous carbon dioxide-rich recovery product. The method of effecting release of gaseous carbon dioxide-rich intermediate from the carbon dioxide-comprising liquid solution feed includes effecting release of at least a fraction of the dissolved carbon dioxide from the carbon dioxide-comprising liquid solution feed. The method of effecting release of at least a fraction of the dissolved carbon dioxide from the carbon dioxide-comprising liquid solution feed includes effecting an increase in temperature of the carbon dioxide-comprising liquid solution feed. The method of effecting dissolution includes effecting dissolution by contacting the separation process feed material with an operative dissolution agent within a contacting zone. The other materials of the separation process feed material includes at least one relatively less soluble material, where relative to carbon dioxide each one of the relatively less soluble material is less soluble within the operative dissolution agent, when the operative dissolution agent is disposed within the contacting zone. When the contacting effects production of an intermediate operative carbon dioxide supply comprising a mixture includes a carbon dioxide-comprising solution intermediate, the intermediate includes dissolved carbon dioxide. The process further involves: effecting separation of the carbon dioxide-comprising liquid solution product from the intermediate operative carbon dioxide supply-comprising mixture, where the carbon dioxide-comprising liquid solution product includes at least a fraction of the carbon dioxide-comprising solution intermediate. The method of effecting separation of the carbon dioxide-comprising liquid solution product from the intermediate operative carbon dioxide supply-comprising mixture includes separation effected by gravity separation. In the process, each one of (i) the dissolution of at least a fraction of the carbon dioxide of the separation process feed material, and (ii) the separation of the carbon dioxide-comprising liquid solution product from the intermediate operative carbon dioxide supply-comprising mixture, is effected in a contacting zone. The carbon dioxide-comprising liquid solution feed is supplied to a carbon dioxide recovery zone to effect release of a gaseous carbon dioxide-rich intermediate from the carbon dioxide-comprising liquid solution feed within the carbon dioxide recovery zone, where the temperature of the contacting zone is lower than the temperature of the carbon dioxide recovery zone. In the process, at least a fraction of the operative dissolution agent is supplied to the contacting zone in the form of a mist. The concentration of carbon dioxide within the separation process feed material is at least two vol.% based on the total volume of the separation process feed material. At least a fraction of the carbon dioxide-rich separation fraction is flowed through an eductor prior to supplying to the reaction zone. At least a fraction of the carbon dioxide-rich separation fraction is supplied to the reaction zone with a prime mover. At least a fraction of the carbon dioxide-rich product material supplied to the reaction zone is flowed through an eductor prior to supplying to the reaction zone.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The relatively less soluble material includes at least one of nitrogen, oxygen, and carbon monoxide. The separation process feed material further includes at least one of sulfur oxides (SOx), nitrogen oxides (NOx), and ammonia (NH3). At least one of SOx, NOx, and NH3 is supplied by the gaseous exhaust material. EXAMPLE - No suitable example given.
