A carbon dioxide capture system based on a biphasic solvent, comprising an absorption tower, a phase separator, a first type of power device, a heat exchange regenerator, a heat pump, and a plurality of second type of power devices,
- a mixed absorbent outlet of the absorption tower being connected to an absorbent inlet of the phase separator via one of the second type of power devices, a lean-phase solvent outlet of the phase separator being connected to a mixed absorbent inlet of the absorption tower via one of the second type of power devices,
- a rich-phase solvent outlet of the phase separator being connected to a rich-phase solvent inlet of the heat exchange regenerator via the first type of power device, a regenerated absorbent outlet of the heat exchange regenerator being connected to a first inlet of the heat pump, a first outlet of the heat pump being connected to the mixed absorbent inlet of the absorption tower,
- a heat exchange medium outlet of the heat exchange regenerator being connected to a second inlet of the heat pump, a second outlet of the heat pump being connected to a heat exchange medium inlet of the heat exchange regenerator via one of the second type of power devices, and
- the heat exchange regenerator comprising a gas discharge port for discharging carbon dioxide desorbed in the heat exchange regenerator.
