摘要:A system of apparatus and process for synthesizing ammonia are disclosed, which includes first and second catalytic synthesis converters with a heat exchanger interposed therebetween and operatively connected to the inlet and outlet of one converter and to the inlet of the other converter to permit a feed gas stream to be passed in heat exchange relationship with a partially synthesized gas stream passing from the outlet of the first converter to the inlet of the second converter. The converters and heat exchanger are mounted on a support platform, with one converter and heat exchanger mounted for movement with respect to the platform to accommodate dimensional changes caused by thermal expansion during operation.

发明人：KORCHNAK JOSEPH D; DUNSTER MICHAEL; ENGLISH ALAN
权利人:DAVY MCKEE CORP
摘要:A hydrogen rich gas is produced from hydrocarbonaceous feedstock by subjecting the feedstock to catalytic partial oxidation under temperature and steam conditions avoiding production of free carbon, thereby producing a synthesis gas containing hydrogen, carbon monoxide and carbon dioxide; converting carbon monoxide to carbon dioxide by water gas shift reaction; and removing carbon dioxide.
