H2 recovery with membrane
H2 recovery with membrane
(OP)
I'm looking for a membrane separation equipment that can purify H2 (from 60% to approx. 99%), other gases in the stream are CO,H2O,CO2 and N2.
temp: are initally 800oC, but can be cooled
pressure: atmospheric (can be compressed)
Anyone who knows a company who can deliver this? I'm espacially interested in ceramic membranes if they can handle the temp.

RE: H2 recovery with membrane
I don't have any vendors to suggest to you, but there are membrane suppliers out there with a variety of membranes (metallic and otherwise) for this job. I think you can count on the need for cooling the reformate a long way below 800 C, though.

Air Liquide [my choice, OTOH they pay me to say that *-)]

these are all polymeric membranes and there are probably others. Last I checked, there are no fully commercialized ceramic membranes for gas separation. Metallic membranes are available but are aimed at ultra high purity applications (tritium/helium, GC H2 etc) As they use Pt/Pd as the membrane, I'm not sure passing your stream over them would produce reactions anyway.
Polymeric membranes means cooling to 80-90° C, and a compression step, so the economics of this versus competing technologies are unclear.
I would try H2 companies (such as AP and AL), and the membrane engineering section of eng-tips, where I think this was discussed once.

This is the best ref that I could find.
