The invention concerns a method and a system for extracting and storing carbon dioxide of fumes derived from combustion of hydrocarbons in an apparatus designed in particular to produce mechanical energy. The system comprises: extracting means, in particular exchangers (11, 25) and a dehydrator (56), for extracting water from said fumes in liquid form at a pressure substantially equal to atmospheric pressure; cooling means, in particular an integrated cascaded refrigerating apparatus (18, 22, 25, 26, 28, 32, 33, 34, 39, 40), for cooling said fumes at a pressure substantially equal to atmospheric pressure and at a temperature such that the carbon dioxide passes directly from vapour state to solid state, through an anti-sublimation process; storage means, in particular a fixed (49) and/or removable (51) reservoir and suction means, in particular a pneumatic pump for storing carbon dioxide in liquid form after defrosting.
L'invention concerne un procédé et un système d'extraction et de stockage du dioxyde de carbone des fumées provenant de la combustion d'hydrocarbures. dans un appareil destiné notamment à la production d'énergie mécanique. Le système comporte: des moyens d'extraction, notamment des échangeurs (11, 25) et un déshydrateur (56), pour extraire desdites fumées l'eau sous forme liquide à une pression sensiblement égale à la pression atmosphérique; des moyens de refroidissement, notamment un appareil frigorifique à cascade intégrée (18, 22, 25, 26, 28, 32, 33, 34, 39, 40), pour refroidir lesdites fuméesà une pression sensiblement égaleà la pression atmosphérique et à une température telle que le dioxyde de carbone passe directement de l'état vapeur à l'état solide, via un processus d'anti-sublimation; des moyens de stockage, notamment un réservoir fixe (49) et/ou amovible (51) et des moyens d'aspiration, notamment une pompe pneumatique (48), pour stocker le dioxyde de carbone sous forme liquide après dégivrage.
