Abstract
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 comprises: exchangers (11, 25) and a dehydrator (56), for extracting water from the fumes in liquid form at a pressure more or less equal to atmospheric pressure; an integrated cascaded refrigerating apparatus (18, 22, 25, 26, 28, 32, 33, 34, 39, 40), for cooling the 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; 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.
