Abstract
Provided are a supply apparatus and a supply method for supplying fluid carbon dioxide that are energy-saving and efficient. The supply apparatus for supplying fluid carbon dioxide includes: a circulation system including a purifying unit that removes impurities and contaminants from the carbon dioxide, a storage unit that includes a condenser for changing gaseous carbon dioxide passed through the purifying unit into liquid carbon dioxide, a supply unit that includes a first pump for supplying the liquid carbon dioxide in the storage unit to a use point, and a return line through which excess carbon dioxide supplied from the supply unit but not used at the use point is returned to the storage unit; and a carbon dioxide introduction unit that introduces carbon dioxide, as a starting material or recovered gas, to the circulation system. The carbon dioxide introduction unit includes a second pump for increasing the pressure of the carbon dioxide and the second pump introduces the carbon dioxide to the circulation system.
