Abstract:
A method for removing carbon dioxide from a gaseous source, the method comprising: (i) contacting said gaseous source with an aqueous solution of a carbon dioxide sorbent that reacts with carbon dioxide to form an aqueous-soluble carbonate or bicarbonate salt of said carbon dioxide sorbent; (ii) contacting the aqueous solution from step (i) with a bis-iminoguanidine carbon dioxide complexing compound, which is different from the carbon dioxide sorbent, to result in precipitation of a carbonate or bicarbonate salt of said carbon dioxide complexing compound and regeneration of the carbon dioxide sorbent; and (iii) removing the precipitated carbonate or bicarbonate salt from the aqueous solution in step (ii) to result in a solid form of said carbonate or bicarbonate salt of the carbon dioxide complexing compound. The method may further include a step (iv) of regenerating the carbon dioxide complexing compound by subjecting the precipitated salt to sufficient heat and/or vacuum.

Claim (Index 6):
The method of  claim 1 , further comprising: (iv) regenerating the carbon dioxide complexing compound by subjecting the carbonate or bicarbonate salt of said carbon dioxide complexing compound to heat, vacuum, or both, sufficient to result in release of carbon dioxide gas emanating from said carbonate or bicarbonate salt of said carbon dioxide complexing compound along with simultaneous restoration of the carbon dioxide complexing compound, wherein the released carbon dioxide gas is either quarantined for storage and/or converted into a useful product.
