An apparatus for the regeneration of an aqueous amine absorption solution rich in captured CO 2 and the recovery of absorbed CO 2 therefrom comprising: a containment structure defining a process volume; a supply conduit to pass CO 2 rich absorption solution into the process volume; condensing heating means comprising a reboiler fluidly connected to the process volume to heat the CO 2 rich absorption solution and thereby cause CO 2 to dissociate from the absorption solution and to form a CO 2 rich vapour phase including solution vapour; a vapour recompression system fluidly connected to the process volume to receive the CO 2 rich vapour phase output from the process volume and to compress the same; a compressed vapour supply conduit to supply output compressed vapour to the reboiler as a source of thermal energy therefor; a condenser to receive the compressed vapour from the reboiler and condense and recover solution vapour from the compressed vapour phase comprising conduit means to feed recovered solution condensed from the vapour phase back into the containment structure and conduit means to output a resultant substantially pure CO 2 gas phase to a compression system for storage; providing a secondary source of thermal energy for the reboiler comprising, fluidly in series: a receiving conduit connected to a thermal power plant for receiving cold reheat steam from the thermal power plant; a back pressure turbine disposed to drive the vapour recompression system to extract work from and reduce the pressure of the cold reheat steam; a delivery conduit to deliver the resultant lower pressure steam to the reboiler as a further source of thermal energy therefor. a containment structure defining a process volume; a supply conduit to pass CO 2 rich absorption solution into the process volume; condensing heating means comprising a reboiler fluidly connected to the process volume to heat the CO 2 rich absorption solution and thereby cause CO 2 to dissociate from the absorption solution and to form a CO 2 rich vapour phase including solution vapour; a vapour recompression system fluidly connected to the process volume to receive the CO 2 rich vapour phase output from the process volume and to compress the same; a compressed vapour supply conduit to supply output compressed vapour to the reboiler as a source of thermal energy therefor; a condenser to receive the compressed vapour from the reboiler and condense and recover solution vapour from the compressed vapour phase comprising conduit means to feed recovered solution condensed from the vapour phase back into the containment structure and conduit means to output a resultant substantially pure CO 2 gas phase to a compression system for storage; providing a secondary source of thermal energy for the reboiler comprising, fluidly in series: a receiving conduit connected to a thermal power plant for receiving cold reheat steam from the thermal power plant; a back pressure turbine disposed to drive the vapour recompression system to extract work from and reduce the pressure of the cold reheat steam; a delivery conduit to deliver the resultant lower pressure steam to the reboiler as a further source of thermal energy therefor. a receiving conduit connected to a thermal power plant for receiving cold reheat steam from the thermal power plant; a back pressure turbine disposed to drive the vapour recompression system to extract work from and reduce the pressure of the cold reheat steam; a delivery conduit to deliver the resultant lower pressure steam to the reboiler as a further source of thermal energy therefor.
