Abstract

316,735. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 13, 1928. Nitrogen oxides.-In the alkaline absorption of nitrogen oxides from gases containing them in small proportion, the gases are, prior to alkaline absorption, oxidized by treatment with nitric acid either by injecting the acid into the gases or by passing the gases through aqueous nitric acid of about 45 per cent strength at about 60‹ C. A gaseous mixture containing nitric oxide and excess of oxygen is subjected to alkaline absorption, and when the gas still contains 5-6 grm. nitric oxide per cubic metre is treated with nitric acid and afterwards again subjected to alkaline absorption.
