Title:
LIQUID HYDROGEN VAPORIZATION SYSTEM
Document Type and Number:
Japanese Patent JP2023164132
Kind Code:
A
Abstract:
To provide a technique which can effectively use the cold heat energy of liquid hydrogen when producing hydrogen gas from liquid hydrogen.SOLUTION: A liquid hydrogen vaporization system 100 in one embodiment comprises: a heat exchanger 51 for exchanging heat between liquid hydrogen and gaseous air; an air-liquid separator 52 for separating air-liquid two-phase hydrogen output from the heat exchanger 51 into gas and liquid; a liquid air drum 54 in which liquid air output from the heat exchanger 51 is held; a condenser 53 for condensing the gaseous air evaporated from the liquid air drum 54 using the liquid hydrogen separated by the gas-liquid separator 52; and a rectification tower 55 provided between the liquid air drum 54 and the condenser 53, and performing rectification through contact of the gas evaporated from the liquid air drum 54 with the liquid which is condensed by the condenser 53 and is made to flow back.SELECTED DRAWING: Figure 2
