STRATIFICATION PREVENTING METHOD FOR LOW-TEMPERATURE LIQUEFIED GAS IN LOW-TEMPERATURE LIQUEFIED GAS TANK

PURPOSE:To prevent breakage of a tank due to the stratification of low-temperature liquefied gas by drawing up liquefied gas in the bottom portion of the tank to be jetted above the liquid surface of the tank. CONSTITUTION:Old liquid 2 of low density and new liquid 3 of high density form upper and l...

Zusammenfassung:	PURPOSE:To prevent breakage of a tank due to the stratification of low-temperature liquefied gas by drawing up liquefied gas in the bottom portion of the tank to be jetted above the liquid surface of the tank. CONSTITUTION:Old liquid 2 of low density and new liquid 3 of high density form upper and lower layers in a low-temperature liquefied gas storing tank 1, wherein a convection occurs in each layer. An opening 10 for taking out the new liquid 3 is disposed on the bottom portion of the tank 1, and the new liquid 3 is sprayed from a jet 14 by a pump 11. Therefore, the stored energy of the new liquid 3 is continuously emitted by evaporation, which results in that a great deal of energy is not emitted at one time.
