Abstract

This paper discusses low-temperature storage of hydrogen, and safety in the refining stage thereof. Discussions were given on a device to discharge safely hydrogen evaporated from a liquefied hydrogen storing tank rolly. A testing equipment of a 1/10 size of a full size equipment was fabricated on a trial basis. The equipment was used to test discharging a gaseous mixture containing hydrogen at concentration of about 2%, while air is being supplied from a blower directly connected to a gas motor (rotating on gas pressure) with treatment rate of 15 Nm{sup 3}/h. In order to keep the hydrogen concentration below the lower explosion limit of 4%, uniformity in the spatial distribution of the concentration is important. Full consideration should be given thereto in future designing works. With a cryogenic adsorption refining device for hydrogen, oxygen content is adsorbed, and hydrogen is refined. During regeneration of the adsorption device, oxygen is discharged. Experiments on regeneration methods were performed for comparing and discussing oxygen discharge behavior by using three systems: nitrogen purge, hydrogen purge, and temperature raising. Cases were found in which oxygen concentration in the exhaust gas exceeds the lower explosion limit of 4%. There is a number of important assignments  More>>

The present experiments have great significance in providing fundamental items of information. (NEDO)}
