Abstract
Carbonate salts are efficiently produced from carbon dioxide in exhaust gas. The method for producing carbonate salts includes an atomizing step that forms an aqueous alkaline solution mist with an atomizer; a mixing step that mixes exhaust gas with the aqueous alkaline solution mist produced in the atomizing step to absorb exhaust gas carbon dioxide in the mist and combine mist positive ions with the carbon dioxide to produce mist that contains carbonate salt; and a separating step that separates the mist that contains carbonate salt produced in the mixing step from exhaust gas.
Claims9
A method for producing carbonate salts, the method comprising:
- an atomizing step that forms an aqueous alkaline solution mist with an atomizer;
- a mixing step that mixes exhaust gas with the aqueous alkaline solution mist produced in the atomizing step, absorbs exhaust gas carbon dioxide into the mist, and combines mist positive ions with the carbon dioxide to form mist that contains carbonate salt;
- and
- a separating step that separates the mist that contains carbonate salt produced in the mixing step from exhaust gas,
- wherein the atomizer ultrasonically vibrates the aqueous alkaline solution to form mist in the atomizing step, and
- wherein the mixing step further comprises detecting a temperature and a humidity and adjusting flow rates of the exhaust gas and the mist with a controller to maintain an internal temperature at or below a dew point to suppress vaporization of the mist.
