I have a process to recover H2SO4 from spent acid dillute stream in any
industry, which is finally converted to Ammonium Sulphate efficiently
without much operating cost.
This Ammonium sulphate is anhydrous.
Now I am looking for either converting it back to conc. H2SO4 & recycle ammonia.
That's halfway there. You could decompose it further, but temperatures that high would probably be uneconomical.chemoleo - 6-6-2006 at 17:33
Tsts, neutrino, but how would you seperate the acid from the ammonia? It's something I wondered many a time... and the only thing I can think of is
some separation of mass at high heat, i.e. while the AS is still in the form of NH3, H2O and SO3. Probably would work through ionisation, similar to a
mass spectrometer.
I can't see an easy method though.

Electrolysis

Electrolysis with the separation of the anode and cathode products may be useful. There
is a similar method in industry using a membrane, or bridge for the home chemist, used to
separate sodium chloride. Collecting the ammonia at the cathode could be a problem.
There may not be an easy or feasible solution depending on what you want to achieve.
I offer it only as a possibility.technologist - 7-6-2006 at 04:17
Hey Guys,
I am looking for a commercial process not Academic info from Literature or a process which is not feasible beyond lab.
