Liquefied gas-processing system and method

The invention liquefied gas treatment system, and relates to a method, a liquefied gas storage tank, the liquefied gas supply line connected to the demand from; Pump which is provided on said liquefied gas supply line, pushing the liquefied gas discharged from the liquefied gas storage tank; Heat exchanger that is provided on said liquefied gas feed line between the consumer and the pump, heat exchanger and heat transfer medium for liquefied gas supplied from the pump; Medium heater for heating the heat transfer medium; Connected to the heater from the medium to the heat exchanger medium circulation line; Group calculation for calculating an amount of heat flow of the liquefied gas to be fed into the heat exchanger, and to calculate the necessary quantity of heat of the heat transfer medium on the basis of the flow rate and the state of the liquefied gas to the demand the needs of the liquefied gas; And characterized by a controller for varying the amount of heat that the flow rate or the medium heating the heat transfer medium flowing in the medium, heater fed to the heat transfer medium by receiving the necessary heat quantity of the heat transfer medium from the exchanger the heat output It shall be. Liquefied gas-processing system and method according to the invention, with the liquefied gas flow rate and temperature before entering the heat exchanger, the heat of the heat transfer medium, calculates the required amount of heat and, with the calculated amount of heat to be heated to the required temperature of the consumer by implementing a feed forward control of controlling, it can be efficiently heated to the required temperature liquefied gas demand. In addition, the liquid-gas treatment system and method, measuring the temperature of the liquefied gas flowing into the heat exchanger by liquefied gas temperature sensors, and flow rate and the temperature of the back over the RPM of the pump identify the flow rate of the liquefied gas, liquefied gas, according to the invention by calculating a necessary heat quantity, the flow rate of the heat transfer medium flowing into the heater, or adjusting the amount of the heat source medium supplied to the heat transfer medium can be efficiently controlled by the temperature of the liquefied gas.
