Title:
METHOD FOR SUPPLYING REFINED LIQUEFIED GAS
Document Type and Number:
WIPO Patent Application WO/2010/134301
Kind Code:
A1
Abstract:
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 discharging the gas constituting a gas phase part within the storage container.
The method for supplying a refined liquefied gas is characterized in that a raw liquefied gas in a refinement tank, the raw liquefied gas containing highly volatile impurities, is refined by implementing the following operations and is then supplied to a receiver.
(1) An operation in which the concentrations of the impurities in the gas phase are determined, then the concentration of each impurity in the liquid phase is estimated from the ratio between the liquid-phase concentration and the gas-phase concentration of the impurity (gas-liquid equilibrium constant (Kn)), and the amount of the gas to be discharged from the gas phase part within the refinement tank in order to refine the liquefied gas is assumed,
(2) an operation in which the gas is discharged from the gas phase part to thereby refine the liquefied gas constituting the liquid phase,
(3) an operation in which after completion of the discharge, the gas phase is sampled and the quality of the refined liquefied gas is ascertained, and
(4) an operation in which after the quality of the refined liquefied gas is ascertained, the refined liquefied gas is supplied to a receiver from the refinement tank.
