Vaporizer in reliquefaction system of low temperature liquefied gas tank

Abstract

Abstract PURPOSE:To devise to send gas to a compressor in almost perfect gas phase by heating the gas introduced from a low temperature liquified gas tank in liquid phase as well as in gas phase by hot discharged gas from the compressor. CONSTITUTION:A vaporizer 2 for a reliquefaction system 1 to reliquefy the gas vaporized in a low temperature liquefied gas tank 3 through a compressor 7 is composed of a heating unit consisting of the first heat-exchanging part (a heat-exchanger trunk 14) to pass the gas from the above-written low temperature liquefied gas tank 3 and the second heat-exchanging part to pass heated fluid, and a connecting means between the second heat-exchanging part (a heating pipe 15) and the discharge side of the above-written compressor 7. In this construction, since the gas from the low temperature liquefied gas tank 3 is heated by the hot discharged gas from the compressor 7 and supplied to the compressor 7 in gas phase, the disuse of a thermal source permits to reduce the energy, the equipment cost, and the driving cost.
