Abstract

The present invention relate to liquefied gas treatment system and method. A liquefied gas treatment system includes: a liquefied gas supply line connected from a liquefied gas storing tank to a source of demand, a heat exchanger provided on the liquefied gas supply line between the source of demand and the liquefied gas storing tank and configured to exchange heat between the liquefied gas supplied from the liquefied gas storing tank and heat transfer media, a media heater configured to heat the heat transfer media, a media circulation line connected from the media heater to the heat exchanger, a liquefied gas temperature sensor provided on the liquefied gas supply line, and configured to measure a temperature of the liquefied gas, and a controller configured to make the measured temperature of the liquefied gas be equal to or higher than a demanded temperature of the source of demand in such a manner that the controller decreases a flow rate of the heat transfer media flowing into the media heater. The liquefied gas treatment system and method of the present invention may decrease a circulation rate of the heat transfer media in such a manner that a difference between temperatures of the heat transfer media at front and rear ends of the heat exchanger is sufficiently maintained, thereby improving efficiency of circulation of the heat transfer media, and heating liquefied gas at an appropriate temperature to supply the heated liquefied gas to a source of demand.
