Abstract: An apparatus for solvent regeneration in carbon capture processes is provided. The apparatus comprises one or more of: (a) a spouted fluid bed reactor with one or more of: (i) a cylindrical shape; (ii) a removable draft tube; (iii) a removable cone base; (iv) a removable nozzle; (v) at least one steam/vapor inlet and at least one steam/vapor outlet; and (vi) at least one liquid inlet and at least one liquid outlet; or (b) an apparatus comprising (i) a spouted fluid bed reactor with a removable conical base and removable draft tube; (ii) at least one reboiler; (iii) a vapor monitoring system; and (iv) a liquid monitoring system. Also disclosed are processes for the separation of CO2 from CO2-containing amine solvents using such apparatus, and methods of using such apparatus.
