Abstract
A liquefied carbon dioxide producing apparatus that can generate high-purity liquid COfree from moisture and organic matter such as oil includes: a recirculating system that carries out a recirculating treatment on CO; and an introduction device that introduces COfrom an external source of COinto the recirculating system. The recirculating system includes at least an evaporator that vaporizes CO, a condenser that condenses COfrom an outlet of the evaporator, and a storage tank that stores liquid COgenerated by the condenser. The liquid COin the storage tank is fed to a point-of-use and to the evaporator. An adsorption device that removes moisture and organic matter (oil) is provided on a line from the external source of COto the condenser at a position where COgas flows.
