    摘要： A retrofit method for increasing production capacity of an ammonia plant having a front end including in series primary and secondary reformers and a shift converter for reacting a hydrocarbon feed, steam and air to form a make-up syngas stream comprising hydrogen and nitrogen at about design stoichiometry, and a synthesis loop wherein a recycle syngas stream is combined with the make-up gas to form a syngas feed to ammonia converters. The retrofit involves the installation of an air separation unit to supply oxygen and nitrogen streams. The oxygen is used to enrich air supplied to the secondary reformer and increase the hydrogen content of the make-up gas substantially above the design stoichiometry and capacity. The nitrogen stream is supplied to the synthesis loop to obtain a desired hydrogen to nitrogen ratio in the syngas feed to the ammonia converters and compensate for the excess hydrogen in the make-up gas. The synthesis loop, if desired, is upgraded to include a high activity catalyst converter for increased ammonia production.

    摘要： Hydrocarbon partial oxidation products are produced by contacting a hydrocarbon with oxygen obtained from an air separation unit A in a reactor B in the presence of a partial oxidation reaction catalyst. After separation of the partial oxidation product from the reactor effluent in unit C, unreacted hydrocarbon is recovered from the effluent in a separator D by adsorbing the unreacted hydrocarbon onto an adsorbent at superatmospheric pressure and removing the adsorbed hydrocarbon from the adsorbent by depressurising said adsorbent and purging the adsorbent with nitrogen obtained from the air separation unit A. The recovered unreacted hydrocarbon is recycled to the partial oxidation reactor B.
