Process for treating an exhaust gas containing nitrogen oxides and
sulfur oxides
摘要:
A process is described for treating an exhaust gas containing NO.sub.x and SO.sub.x in which NO.sub.x and SO.sub.x are effectively converted into industrially useful products of NH.sub.3, or sulfur by use of an aqueous absorbing solution containing at least iron chelate salt and potassium sulfite.
