US Patent:

40563731, Nov 1, 1977

Filed:

May 12, 1976

Appl. No.:

5/686238

Inventors:

Leonard Roy Rubin - Short Hills NJ

Assignee:

Resource Systems, Inc. - East Hanover NJ

International Classification:

B01D 1300

US Classification:

55158

Abstract:

A hydrogen-purification filter has a closed chamber with a pure-hydrogen outlet. A coil made of thin palladium-alloy tubing is contained in this chamber and has an inlet end and an outlet end accessible from outside the chamber. This coil is of D-section so that in case a leak forms the turn of the coil containing the leak can be excised by cutting at the straight sections on both sides of the leak and the remaining coil rejoined at the straight sections.

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.
