A process for the integrated production of ammonia and methanol from a gas produced by steam reforming a hydrocarbon characterised by a) cooling at least part of said gas by heating a secondary reformer feed b) synthesising methanol from at least part of the stream from stop a) in a methanol synthesis unit c) purging inert gas from the methanol synthesis unit in step b) d) heating the purge (as per step a)) and feeding the heated purge gas to a secondary reformer together with an oxygen-and-nitrogen-containing gas e) passing the effluent from the secondary reformer through a carbon monoxide shift reactor f) separating carbon dioxide from the shift reactor effluent from step e) g) methanating oxides of carbon in the effluent gas from step f) h) producing ammonia from dried effluent from step g). |
