<p>PROBLEM TO BE SOLVED: To provide a liquid manufacturing method and liquid manufacturing facility capable of improving liquefaction efficiency attained from raw material kept in a gaseous state.SOLUTION: A liquid manufacturing method for manufacturing liquid from raw material kept under a gaseous state comprises: a step of supercritical forming for transiting raw material from the gaseous state to a supercritical state; a first expansion step for expanding the raw material to cause the raw material to become a gas liquid mixed state; a gas liquid separating step for separating the raw material kept under the gas liquid mixed state passed through the first expansion step into a first liquid phase portion and a first gaseous phase portion; a second expansion step for expanding the first liquid phase portion along an isentropic line to obtain gas liquid mixture containing a second liquid phase portion of lower temperature and lower pressure than those of the first liquid phase portion; and a third expansion step for expanding the first gaseous phase portion along the isentropic line to obtain gas liquid mixture containing a third liquid phase portion.</p> |
