Abstract
Methods are provided for the selective removal of CO.sub.2 from a multicomponent gaseous stream to provide a CO.sub.2 depleted gaseous stream having at least a reduction, e.g. 30 to 90%, in the concentration of CO.sub.2 relative to the untreated multicomponent gaseous stream. In practicing the subject methods, the multicomponent gaseous stream is contacted with an aqueous fluid, e.g. CO.sub.2 nucleated water, under conditions of selective CO.sub.2 clathrate formation to produce a CO.sub.2 clathrate slurry and CO.sub.2 depleted gaseous stream. A feature of the subject invention is that a CO.sub.2 hydrate promoter is employed, where the CO.sub.2 hydrate promoter is included in the multicomponent gaseous stream and/or the aqueous fluid. The CO.sub.2 hydrate promoter serves to reduce the minimum CO.sub.2 partial pressure required for hydrate formation as compared to a control. The subject methods find use in a variety of applications where it is desired to selectively remove CO.sub.2 from a multicomponent gaseous stream.
