  • Publication number: 20230279445
    Abstract: A mixed gas generated in a methane fermentation tank is supplied to culture tanks. In the culture tanks, water as a culture solution is held and algae are cultured. Carbon dioxide contained in the mixed gas preferentially dissolves in water. That is, carbon dioxide is removed from the mixed gas. As a result, a concentration of methane, which is one component of the mixed gas, increases. The mixed gas is re-supplied to another culture tank or the same culture tank.
