An integrated process for making methanol and ammonia from a hydrocarbon feed stock and air is disclosed. An air separation unit is used to produce substantially pure oxygen and nitrogen gas streams. The oxygen gas is used in the secondary reformer to increase the operating pressure of the reformers so that compression to methanol synthesis pressure may be done by a single stage compressor. The nitrogen gas is used to remove carbon oxides impurities from a ammonia synthesis feed stream in a nitrogen wash unit in addition to supplying the nitrogen reactant in the ammonia synthesis gas. Use of nitrogen wash obviates the need for steam shift and methanation reactions used in prior art processes.

A low energy process for the production of hydrogen-rich gas which involves the process sequence of primary reforming and secondary reforming includes parallel steam reformers for the primary reforming of the hydrocarbon feed, one portion of the hydrocarbon feed being heated using radiant heat, i. e. , a steam reforming furnace, and another portion of the hydrocarbon feed being heated using indirect heat exchange with the effluent from the secondary reforming, i. e. , an exchanger-reactor.

Synthesis gases are produced by reaction of steam, oxidant, and a major portion of fresh hydrocarbon feed in an exothermic catalytic reforming zone to a first reformed gas having very low methane content. The balance of the fresh feed is reacted with steam in an endothermic catalytic reforming zone to a second reformed gas having a low methane content. The first and second reformed gases are combined and passed in indirect heat exchange with reactants in the endothermic reforming zone to provide all of the heat required therein and are then recovered as product synthesis gases.
