METHOD AND APPARATUS FOR PRODUCING HIGH-PURITY LIQUEFIED CARBON DIOXIDE |
摘要 |
A liquefied carbon dioxide producing apparatus that can generate high-purity liquid CO2 free from moisture and organic matter such as oil includes: a recirculating system that carries out a recirculating treatment on CO2; and an introduction device that introduces CO2 from an external source of CO2 into the recirculating system. The recirculating system includes at least an evaporator that vaporizes CO2, a condenser that condenses CO2 from an outlet of the evaporator, and a storage tank that stores liquid CO2 generated by the condenser. The liquid CO2 in 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 CO2 to the condenser at a position where CO2 gas flows. |
