MODELING OF THERMAL RESISTANCE OF INSULATION OF TANK AND THE RANGE OF THE VENTED STEAM IN LIQUEFIED NATURAL GAS CARRIERs
The paper considers the theoretical research concerning the account of the vented steam and thermal resistance of insulation of the liquefied natural gas carriers in case of the liquefied gas transportation depending on the type of liquefied gas, the tonnage of liquefied natural gas carrier and the environment conditions. The data to define the thermal resistance of insulation of liquefied natural gas carrier by the condition of providing the set daily vented steam and the amount of the vented steam during transportation are received. The obtained analytical data allow to simulate the range of the vented steam of the liquefied gas (liquefied natural gas, oil gases, ammonia, etc.) depending on temperature of the environment, the value of thermal resistance of insulation, the tonnage of liquefied natural gas carrier and construction of the tanks of liquefied natural gas carrier. The results of the research can be used for the technic-economical definition of the amount of relative daily vented steam and thermal resistance of insulation.
