FIELD: chemistry.
SUBSTANCE: method includes exothermically reacting a first portion of a hydrocarbon feed stream with an oxidant gas comprising molecular oxygen to produce syngas; endothermically reforming a second portion of the hydrocarbon feed stream with steam over a catalyst in a heat exchange reactor to produce syngas; combining the formed products to produce a combined syngas stream; cooling the combined syngas stream to produce steam in a heat recovery boiler; catalytically reacting the combined syngas stream in a catalytic carbon monoxide shift reactor to produce a stream including additional H2 and CO2; cooling the obtained stream to produce steam; removing CO2 from the stream to produce a CO2-depleted stream; removing the substantially pure, high-pressure H2 stream from the CO2-depleted stream using multilayer pressure shift adsorption systems; and combining the substantially pure, high-pressure H2 stream with a substantially pure, high-pressure N2 stream to produce ammonia, wherein the ammonia is produced independently of the blow-off loop.
EFFECT: efficient ammonia production.
