Hydrogen in exhaust gases

I’m not sure about the pressure conditions; generally, it can be purified using pressure swing adsorption before further use.
The off-gas obtained after the recovery of acetylene and vinyl chloride via pressure swing adsorption contains over 80% hydrogen, which can be recovered as hydrochloric acid again using pressure swing adsorption.
