Abstract:
Disclosed is a process for removing acid gases from gaseous streams by contacting the stream with an aqueous scrubbing solution containing a heterocyclic nitrogen compound comprised of either a five-- or six--membered ring having a pKa no greater than about 8. Imidazole is a preferred heterocyclic nitrogen compound.
