METHOD OF INJECTING AND REACTING SUPER-CRITICAL PHASE CARBON DIOXIDE WITHOUT PRESSURE LOSS

摘要

Disclosed is provided a method of injecting and reacting super-critical phase CO2 without pressure loss. The method includes preparing gas phase CO2, producing liquid phase CO2 by pressurizing the prepared gas phase CO2, producing super-critical phase CO2 by adjusting a temperature of the produced liquid phase CO2, filling incompressible fluid in a reactor and an injection line from an injection unit and pressurizing the incompressible fluid, injecting the produced super-critical phase CO2 into the reactor, and controlling a pressure of the injected super-critical phase CO2 by a pressure regulating unit.

1. A method of injecting and reacting super-critical phase carbon dioxide without pressure loss, the method comprising:
(A) preparing gas phase carbon dioxide; (B) producing liquid phase carbon dioxide by pressurizing the prepared gas phase carbon dioxide; (C) producing super-critical phase carbon dioxide by adjusting a temperature of the produced liquid phase carbon dioxide; (D) filling incompressible fluid in a reactor and an injection line from an injection unit and pressurizing the incompressible fluid; (C) injecting the produced super-critical phase carbon dioxide into the reactor; and (F) controlling a pressure of the injected super-critical phase carbon dioxide by a pressure regulating unit, wherein the gas phase carbon dioxide is changed into the liquid phase carbon dioxide by pressurizing the gas phase carbon dioxide to a pressure at a critical point by a booster pump and transferred to a piston pump provided next to the booster pump in step (B), the liquid phase carbon dioxide is changed into the super-critical phase carbon dioxide by heating the liquid phase carbon dioxide to a temperature at the critical point or more by a heater installed at an outer peripheral portion of a pump body when the liquid phase carbon dioxide passes through the pump body of the piston pump in step (C), water or salt water is filled as the incompressible fluid and the super-critical phase carbon dioxide is pressurized beyond the critical point in step (D), and the super-critical phase carbon dioxide injected into the reactor is maintained at the critical point by using a thermometer and a pressure gauge in step (E), such that the super-critical phase carbon dioxide reacts with a sample in the reactor without phase change of the super-critical phase carbon dioxide.
