摘要： A waste heat recovery system includes at least two integrated rankine cycle systems coupled to at least two separate heat sources having different temperatures. The first rankine cycle system is coupled to a first heat source and configured to circulate a first working fluid. The second rankine cycle system is coupled to at least one second heat source and configured to circulate a second working fluid. The at least one second heat source includes a lower temperature heat source than the first heat source. The first and second working fluid are circulatable in heat exchange relationship through a cascading heat exchange unit for condensation of the first working fluid in the first rankine cycle system and evaporation of the second working fluid in the second rankine cycle system.

The separator includes a first flow path for receiving the compressed exhaust gas, a second flow path for directing a sweep fluid therethrough, and a material with selective permeability of carbon dioxide for separating the first and the second flow paths and for promoting carbon dioxide transport therebetween. The system further includes an expander coupled to the compressor for receiving and expanding the CO2 lean stream to generate power and an expanded CO2 lean stream.

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.
