This may be somewhat unusual: what technology/technologies would you suggest as a starting point for removal of hydrogen as a potentially valuable byproduct from an organic vapor stream at about 25 psig and 400°F? The organics present are all C2 oxygen-containing species; the process is a catalytic dehydrogenation of ethanol. Hydrogen is present in the stream on the close order of 16-17 mole per cent.
I thought of pressure swing adsorption but I believe that's the solution to the inverse problem; i.e., how one removes small amounts of contaminants from a stream that is largely hydrogen itself. Further, I thought hydrogen might be sparingly soluble at most in ethanol/acetaldehyde/etc. and that cooling/condensing the gas stream would permit a physical separation but I'm not entirely convinced (would an equation of state thermodynamic model be best for simulation of this?).
Insights would be most helpful. Thanks.
