System and method for processing liquefied gas

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 the 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 on the media circulation line and configured to measure a state value of the heat transfer media;
• a controller setting a gasification prevention reference value, which is a temperature value for preventing water included in the heat transfer media from being gasified, and changing a flow rate of the heat transfer media flowing into the media heater or changing calories supplied to the heat transfer media by the media heater, on the basis of the state value of the heat transfer media by the media state detecting sensor and the gasification prevention reference value;
• and
• a phase separator provided at a downstream of the media heater on the media circulation line and separating the heat transfer media in which a cracking phenomenon is generated into gas and liquid-state heat transfer media,
• wherein the phase separator discharges a gaseous material to an outside and supplies the liquid-state heat transfer media to the heat exchanger provided on the liquefied gas supply line between the liquefied gas storing tank and the source of demand through the media circulation line, the controller prevents a cracking of the heat transfer media, and the phase separator prepares a case where the cracking of the heat transfer media is generated.
