| 摘要 |
The present invention pertains to a method and system for extracting and storing carbon dioxide from fumes derived from the combustion of hydrocarbons in an apparatus designed in particular for the production of mechanical energy. The system comprises: extracting means, in particular exchangers (11, 25) and a dehydrator (56), for extracting water from the said fumes in liquid form at a pressure more or less 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 the said fumes at a pressure more or less equal to atmospheric pressure and at a temperature such that the carbon dioxide passes directly from the vapor state to the solid state, via an anti-sublimation process; storage means, in particular a fixed (49) and/or removable (51) reservoir and suction means, in particular a pneumatic pump (48), for storing the carbon dioxide in liquid form after defrosting.
