초록

A process for producing ammonia synthesis gas in which a pressure swing adsorption unit is utilized to replace former CO2 removal, methanation, drying and purification steps. To increase the efficiency of the process, a hydrogen fuel cell is utilized to generate electricity and a high purity nitrogen purge stream for a pressure swing absorption unit. Accordingly, after reforming and high temperature catalytic shift conversion, the feed stream is divided into a first stream to feed the fuel cell and a second stream which is directly introduced to the pres...

청구항

An improved process for reforming hydrocarbons to obtain a synthesis gas containing an approximately stoichiometric amount of hydrogen and nitrogen from which ammonia may be formed in which a hydrocarbon is reacted with steam and air in a reforming operation to obtain a first effluent comprising hydrogen, nitrogen and carbon monoxide, the carbon monoxide being reacted in a shift conversion stage to produce a second effluent comprising hydrogen, nitrogen, and carbon dioxide, said improved process comprising the additional steps of separating said second e...
