An improved process for reducing nitrogen oxide emissions to the atmosphere comprises the injection of ammonia vapor, formed by the vaporization of an aqueous ammonia solution, into a combustion effluent. A dilute aqueous ammonia phase, produced by such vaporization, may also be injected, either in vapor or liquid form, into a combustion effluent. Temperature and pressure control of such vaporization may be used to maintain the desired concentration of ammonia injected into the combustion effluent. |
