ABSTRACT:
Disclosed is an integrated process for the production of methanol and ammonia which comprises the steps of subjecting a gaseous hydrocarbon feed to primary reforming with steam to produce a methanol synthesis gas containing H.sub.2 and CO, synthesizing methanol from this methanol synthesis gas, subjecting the purge gas resulting from the methanol synthesis step to secondary reforming with steam and air to produce an ammonia synthesis gas containing H.sub.2, N.sub.2, CO and CO.sub.2, subjecting this ammonia synthesis gas to high temperature shift conversion for the purpose of reducing its CO content, passing the CO-impoverished ammonia synthesis gas through a series of steps required for the removal of carbon oxides, and subjecting the resulting CO-free ammonia synthesis gas to ammonia synthesis.
