Abstract
The disclosure relates to a method and system (1) for capturing CO2 by reacting CO2 in the flue gas cooled to 600-700° C. after leaving the solid, liquid and gas combustion chamber with calcined eggshell powders in a tangential vortex formed in a cylindrical column (9) and forming CaCO3 as a result of the reaction.
Claims15
A system (1) for capturing CO2 gas, which is the biggest cause of greenhouse gases in the flue gas resulting from the combustion of fossil fuels burned in thermal power plants and industrial boilers, and converting it into CaCO3 characterized by comprising;
- At least one cylindrical column (9) that is cylindrical structure, to increase CO2 capture efficiency,
- At least one cyclone area (11) to keep separate the CaCO3 obtained as a result of the reactions in the cylindrical column (9) from the flue gas,
- At least one feeding system (3) to feed the calcined eggshell to the cylindrical column (9),
- At least one tangential feeding area (8), which allows the calcined powdered eggshell particles to enter the cylindrical column (9) to capture CO2.
A method for capturing CO2 gas, which is the biggest cause of greenhouse gases in the flue gas resulting from the combustion of fossil fuels burned in thermal power plants and industrial boilers, and converting it into CaCO3 characterized by comprising;
- the process steps of;
- Calcining the eggshell (101),
- Tangential feeding of carbon dioxide to a cylindrical column (9) (104),
- Forming calcium carbonate (CaCO3) by the reaction of carbon dioxide with calcined eggshell fed tangentially in the cylindrical column (9) (105),
- Transferring carbon dioxide and calcined eggshell powder to the cyclone area (11) by adjusting the mixing speed by a valve (10) (106),
- Separating flue gas and calcium carbonate (CaCO3) particles in the cyclone and transferring calcium carbonate (CaCO3) under the cyclone area (11) (107).
