A system for recovering carbon dioxide from a carbon dioxide-containing gas includes an absorber configured to absorb carbon dioxide from the carbon dioxide-containing gas with a non-aqueous solvent to form a carbon dioxide-lean gas, the non-aqueous solvent comprising a nitrogenous base, regenerator configured to remove the carbon dioxide from the non-aqueous solvent after the non-aqueous solvent is loaded with carbon dioxide, and an acid wash column configured to remove a second portion of the nitrogenous base from the carbon dioxide-lean gas with a buffered acid solution. Related systems and methods of removing carbon dioxide from a carbon dioxide-containing gas are also disclosed.
