<p>The process involves compressing fumes, and extracting part of the carbon dioxide to produce fumes with a low CO2 content and a high-pressure carbon dioxide. A coolant fluid is vaporized by heat exchange with the high-temperature and low pressure fumes, and with the medium and high-pressure fumes. The vaporized fluid is expanded and mechanical energy recuperated by turbines. - The process involves compressing the fumes, e.g. from a gas turbine (TG) or furnace, first to produce a medium and then a high pressure, extracting part of the carbon dioxide to produce fumes with a low CO2 content and a high-pressure carbon dioxide. A coolant fluid is vaporized by heat exchange with the high-temperature and low pressure fumes, and with the medium and high-pressure fumes as they pass through heat exchangers (E01, E02, E03) with the energy from the heat exchangers recuperated by a turbine (T) linked to a power generator (GE2). The vaporized fluid is expanded and mechanical energy recuperated by turbines (T1, T2), and the fluid is condensed by cooling and then compressed for return to the heat exchangers. The mechanical energy is used for the extraction of carbon dioxide from the high-pressure fumes, and the gas is compressed and stored in an underground tank.</p> |
