METHOD OF GASIFYING LIQUEFIED NATURAL GAS FOR CRYOGENIC SYSTEMS OF VEHICLES Russian patent published in 2007 - IPC F17C7/04 

FIELD: cryogenic engineering.

SUBSTANCE: method comprises evaporating liquid and subsequent heating of evaporated gas. The evaporation is carried out due to the internal energy directly in the cryogenic vessel of the fuel tank caused by the unbalance between the condition of the vapor and liquid phases as a result of the permanent gas withdrawing. To compensate the internal energy taken from the liquid during boiling, an external recuperative evaporator is used. The recuperative evaporator provides supply of the heated gas to the cryogenic vessel. The intensity of supply of the heated gas to the cryogenic vessel is controlled by the velocity of the flow of air heated in the heat exchanger and supplied to the external recuperative evaporator of liquid by the fan with controllable drive.

EFFECT: enhanced efficiency and safety.
