A method for supplying a refined liquefied gas, in which prior to the supply of a liquefied gas stored in a container, the liquefied gas is refined by (1) determining the concentrations of impurities in the gas phase, then estimating the concentration of each impurity in the liquid phase from the ratio between the liquid-phase concentration and the gas-phase concentration of the impurity (gas-liquid equilibrium constant (Kn)), and assuming the amount of the gas to be discharged from the gas phase part within the refinement tank to refine the liquefied gas, (2) discharging the gas from the gas phase part to refine the liquefied gas constituting the liquid phase, (3) sampling the gas phase and ascertaining the quality of the refined liquefied gas, and (4) supplying the refined liquefied gas to a receiver from the refinement tank. |
