Embodiment Construction

[0052] The following is a general description of one application of the invention. Exhaust gas, also known as soot, is typically composed of carbon dioxide (CO 2 ), water vapor (H 2 O) and nitrogen (N 2 ), which also contains some trace components such as CO, NO x , unburned hydrocarbons, etc. (the content of all trace components in the exhaust gas usually does not exceed 1%-2%).

[0053] Table 1 shows the typical molar composition and typical unit mass composition of soot from internal combustion engines:

Abstract

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 (48) for storing carbon dioxide in liquid form after defrosting.

Description

technical field [0001] The present invention relates to a method and system for extracting (capturing) carbon dioxide by anti-sublimation at atmospheric pressure, especially for capturing carbon dioxide contained in smokestacks erected in electricity or heat production or in exhaust pipes of driving engines methods and systems. Carbon dioxide can be stored after capture is performed. Background technique [0002] Carbon dioxide (CO2) emissions from combustion, heating facilities, power generation 2 ) would cause an increase in the concentration of carbon dioxide in the atmosphere, which is unacceptable in the long run. The "Kyoto Agreement" stipulates the obligations of signatory countries to limit carbon dioxide emissions. But curbing usage and improving energy efficiency are not enough to keep CO2 levels within acceptable levels. The capture and storage of carbon dioxide gas has become an integral goal of economic development and maintenance of atmospheric concentratio...
