Abstract
A process for converting ammonia in a gas stream to nitrogen comprises contacting the gas stream with an electrolyte containing bromide and hypobromite ions. The ammonia is dissolved and oxidized by the hypobromite ions to nitrogen. Thereafter the electrolyte is passed through an electrochemical cell containing an anode and a cathode to regenerate the hyperbromite ions by the action of an electric current flowing across the cell. The conversion of ammonia to nitrogen in accordance with the invention is adventageous as nitrogen may be disposed of without harm to the environment whilst ammonia has toxic effects.
