Claim:
1. A liquefied gas treatment system, comprising: 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 liquefied gas supplied from the liquefied gas storing tank and heat transfer media including water; a media heater configured to heat the heat transfer media; a media circulation line connected from the media heater to the heat exchanger; a media state detecting sensor provided at a downstream of the heat exchanger on the media circulation line and configured to measure a state of the heat transfer media; and a controller configured to set a coagulation prevention reference value for preventing water included in the heat transfer media from being coagulated and change a flow rate of the heat transfer media flowing into the media heater or calories supplied to the heat transfer media by the media heater on the basis of a state value of the heat transfer media by the media state detecting sensor and the coagulation prevention reference value so that the state of the heat transfer media is equal to or greater than the coagulation prevention reference value, and the water included in the heat transfer media exchanging the heat with the liquefied gas in the heat exchanger is prevented from being frozen when the liquefied gas is supplied to the source of demand.
