Zusammenfassung:	A method for removing CO2 from a pressurized gas stream with the effluent CO2 remaining at system pressure or higher is disclosed. Specifically, the removal method provides near isothermal absorption of CO2 from a gas stream in a suitable solvent at an elevated pressure and relatively low temperature. The solvent is then removed from contact with the gas stream, and the temperature is increased to such an extent that the CO2 will flash from the solvent. L'invention concerne un procédé d'élimination du CO2 d'un courant de gaz sous pression, l'effluent de CO2 restant à la pression du système ou à une pression supérieure. Plus spécifiquement, le procédé d'élimination permet une absorption presque isotherme du CO2 d'un courant de gaz dans un solvant approprié à une pression élevée et à une température relativement basse. Le solvant est alors séparé du courant de gaz et la température est augmentée de manière à ce que le CO2 se vaporise instantanément du solvant.
