Patent ID: 8459030

Claim:
A system comprising: a process fluid cooler configured to receive a process fluid including carbon dioxide and to extract thermal energy from the process fluid; a carbon dioxide removal system including an absorber configured to receive the process fluid from said process fluid cooler and to transfer carbon dioxide from the process fluid to a removal fluid; and a stripper configured to receive the removal fluid from said absorber and including a reboiler configured to 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, said reboiler outputting a heating fluid; and a stripper condenser configured to extract thermal energy from the reboiler output stream so as to cause condensation of water associated therewith and to remove carbon dioxide therefrom; a compression system configured to receive carbon dioxide from said stripper condenser and to remove thermal energy from the carbon dioxide; and a heat engine configured to operate according to an organic Rankine cycle and further configured to receive thermal energy from at least one of the heating fluid and extracted at said process fluid cooler, at said stripper condenser, and at said compression system.
