Abstract: A supercritical fluid processing apparatus including a supercritical fluid supply module including a gas liquefier to liquefy a gas transferred from a gas supply and provide a liquefied fluid, a storage tank to change the liquefied fluid to a supercritical state and store a supercritical fluid, and an internal pipe connecting the gas liquefier to the storage tank; an exhaust fluid supply module including an exhaust fluid liquefier including a regeneration storage tank to collect a first exhaust fluid from the storage tank, and a refrigerant pipe to liquefy the first exhaust fluid in the regeneration storage tank and maintain the liquefied first exhaust fluid at a predetermined temperature/pressure; a first exhaust pipe to transfer the first exhaust fluid from the storage tank to the exhaust fluid liquefier; and a resupply pipe to resupply the first exhaust fluid collected and liquefied in the exhaust fluid liquefier to the storage tank.
