ABSTRACT:
An apparatus and method are disclosed for the production of pure hydrogen-containing crude gas. The apparatus, in the event of an interruption in power, is easily and rapidly purged of hydrogen. The apparatus includes a passage defined at least in part by a palladium-containing wall, an inlet opening into the passage to permit hydrogen-containing crude gas to diffuse through the wall, a first outlet positioned on the opposite side of the palladium-containing wall from the inlet, to permit removal of pure hydrogen, the second outlet from the passage on the same side of the wall as the inlet to permit removal of bleed gas, means for heating the hydrogen-containing crude gas, means for automatically blocking flow of hydrogen-containing crude gas through the inlet if the power is interrupted, means for introducing flow of a purge gas to the inlet, automatically and only if the power is shut off, and, means communicating with the second outlet to permit bleed gas passing through to by-pass a manually set bleed valve in the event of a loss of power to rapidly remove the bleed gas.
