Title:
PRODUCTION METHOD AND PRODUCTION APPARATUS FOR CARBONATE SALT
Document Type and Number:
WIPO Patent Application WO/2022/014554
Kind Code:
A1
Abstract:
The present invention efficiently produces a carbonate salt from a carbon dioxide gas in an exhaust gas. This production method for a carbonate salt comprises: an atomizing step wherein an aqueous alkali solution is formed into a mist by an atomizer; a mixing step wherein the mist of the aqueous alkali solution obtained in the atomizing step is mixed with an exhaust gas so as to have a carbon dioxide gas in the exhaust gas absorbed in the mist and to form a carbonate salt by bonding positive ions of the mist and the carbon dioxide gas with each other, thereby having the mist contain the carbonate salt; and a separation step wherein the mist containing the carbonate salt obtained in the mixing step is separated from the exhaust gas.
