PROBLEM TO BE SOLVED: To provide a heat reduction method for liquid gas capable of securely controlling a reduced heat amount without increasing the cost on the equipment and the driving force.SOLUTION: There is provided a heat reduction method for liquid gas being a method in which the heat quantity of the liquid gas is reduced in a put out line 7 where makes the pressure of the liquid gas put out from a storage tank 5 increase in a liquid state, and the liquid gas vaporize after the pressure increase, and feed out as a production gas. The heat reduction method comprises a heat reduction step where the heat reduction gas is mixed using a mixer 11 to the liquid gas before the pressure increase so as to reduce the heat, and the heat reduction step is characterized in that the heat quantity of the liquid gas put out from the storage tank 5 and its flow rate are measured, and, based on the measured value, the heat reduction gas flow rate required for the heat reduction is calculated, and the heat reduction gas is fed to the mixer 11 in the range of the calculated flow rate and also in the range of the condensible flow rate within the mixer 11.SELECTED DRAWING: Figure 1 |
