Methods are provided for the selective removal of carbon dioxide from a multicomponent gaseous stream (16) to provide a carbon dioxide depleted gaseous stream (36) having at least a reduction in the concentration of carbon dioxide relative to the untreated multicomponent gaseous stream (16). In the subject methods, the multicomponent gaseous stream (16) is contacted with carbon dioxide nucleated water (14) under conditions of selective carbon dioxide clathrate formation, where the carbon dioxide nucleated water (14) serves as liquid solvent. The subject methods find use in a variety of applications where it is desired to selectively remove carbon dioxide from a multicomponent stream (16), including chemical feedstock processing applications and air emissions control applications.
