METHOD OF AMMONIA PRODUCTION Russian patent published in 2003 - IPC

FIELD: ammonia production. SUBSTANCE: method of production of ammonia from hydrocarbon materials, steam and air includes compression and purification of hydrocarbon material from sulfur, steam and steam-air catalytic conversion of methane, conversion of carbon monoxide, cleaning of produced nitrogen-hydrogen mixture from oxygen-containing compounds, compression, ammonia synthesis in closed cycle. In this case, added to initial air is carbon dioxide in amount of 0.001-0.124 of volume of produced mixture, and this mixture is directed for steam-air catalytic conversion of methane. EFFECT: reduced specific consumption of hydrocarbon materials.
