Title:
LIQUIFIED NATURAL GAS GASIFICATION DEVICE
Document Type and Number:
Japanese Patent JP2684309
Kind Code:
B
Abstract:
PURPOSE: To enable such problems as extension of a heat exchanging panel or complication of pipes and the like to be eliminated by a method wherein a superheater is of a plate fin type heat exchanger, and liquified petroleum gas can be supplied and mixed in a predetermined natural gas passage between the plates.
CONSTITUTION: A superheater 20 is of a plate fin type heat exchanger in which fins 22 are held betwen plates 21 and 21 and a desired number of low temperature natural gas passages 24 closed with spacer bars 23 are piled up. A liquified petroleum gas header tank 26 is installed at an upper part of the exchanger, and injection tubes 27 with many punched holes are inserted into the temperature natural gas passages 24 and arranged there. Then, the tubes communicate with the liquified petroleum gas tank 26 so as to enable liquified petroleum gas to be fed into the passage 24. With such an arrangement as above, it is not necessary to generate natural gas of temperature of 0°C or higher at a front stage and a load at the front stage can be reduced, resulting in that it is possible to reduce the number of heat exchanging panels.
