Abstract

Here is description of technology basics, facilities and experience of long-term operation of pure hydrogen by means of krioadsorption purification of technical hydrogen obtained from water electrolysis. The value of total volumetric portion of admixtures in purified hydrogen amounts to no more than 110–7%. Ordinary steel 40-liter hydrogen cylinders prepared for filling by means of gradual scavenging with deep drained air, nitrogen and purified hydrogen can be used as packing materials for pure hydrogen. When hydrogen is graded for a purity of 99,995 to 99,99999 vol. %, samples for analysis should be collected from every vessel.
