ABSTRACT:
An apparatus for the production of ammonia synthesis gas comprises a hydrocarbon convertor for converting a hydrocarbon feed to an effluent containing hydrogen and carbon monoxide by reaction with air which hydrocarbon convertor includes means to provide air in excess of the stoichiometric amount of nitrogen required for ammonia synthesis. The effluent from the hydrocarbon convertor is in communication with a water gas shift convertor for converting the carbon monoxide in the effluent to carbon dioxide. The water gas shift convertor is in communication with a pressure-swing adsorption system capable of selectively adsorbing carbon dioxide, carbon monoxide, methane and other impurities from hydrogen and a portion of the nitrogen fed in the gas mixture to the pressure swing adsorption system. The pressure swing adsorption system is provided with a conduit for discharging a partially purified ammonia synthesis gas mixture of hydrogen and nitrogen and a conduit for discharging purge gas.
