    摘要: A process fluid cooler can extract thermal energy from a process fluid including carbon dioxide. An absorber can transfer carbon dioxide from the process fluid to a removal fluid. A reboiler can heat the removal fluid so as to cause carbon dioxide to be released from the removal fluid and outputted as part of a reboiler output stream. The reboiler can also output a heating fluid. A stripper condenser can extract thermal energy from the reboiler output stream so as to cause condensation of water associated with the reboiler output stream and to remove carbon dioxide therefrom. A compression system can remove thermal energy from carbon dioxide received from the stripper condenser. A heat engine can be configured to operate according to an organic Rankine cycle, receiving thermal energy from the heating fluid and/or extracted at the process fluid cooler, at the stripper condenser, and/or at the compression system.
