Abstract
The present invention provides a bicarbonate production method suitable for producing a high purity bicarbonate while suppressing loss of carbon dioxide. The bicarbonate production method includes a generation step of generating a bicarbonate by using a mixed gas that contains carbon dioxide, and a concentration of the carbon dioxide in the mixed gas is 30 volume % or more and 95 volume % or less in a standard state.
Claims14
A bicarbonate production method comprising
- a generation step of generating a bicarbonate by using a mixed gas that contains carbon dioxide, wherein
- a concentration of the carbon dioxide in the mixed gas is 30 volume % or more and 95 volume % or less in a standard state.
A bicarbonate production method comprising:
- a concentration step of obtaining, from a raw material gas that contains carbon dioxide, a mixed gas having a higher concentration of carbon dioxide than the raw material gas;
- and
- a generation step of generating a bicarbonate by using the mixed gas.
A bicarbonate production device comprising:
- a concentration part configured to prepare, from a raw material gas that contains carbon dioxide, a mixed gas having a higher concentration of carbon dioxide than the raw material gas;
- and
- a generation part configured to generate a bicarbonate by using the mixed gas.
