| Abstract | TITLE: PROCESS OF PROUCING AMMONIA FROM A NITROGEN/HYDROGEN MIXTURE DERIVED FROM NATURAL GAS. A process for the catalytic production of ammonia from a nitrogen/hydrogen mixture characterized in that natural gas together with O2-rich gas which has an O2 content of at least 70 vol.% is reformed autothermally to form crude synthesis gas as temperatures in the range from 900-1200 degreeC, a pressure of 40 to 100 bar and in the presence of a reforming catalyst, which gas,c alcutlated in the dry state, has an H2 content of 55 yo 75 vol.%, a CO content of 15 to 30 vol.%, a CO2 content of 5 to 30 vol.% and a volume ratio H2: CO of 1.6 to 4, that the crude synthesis gas is extracted fromt he autothermal reformer, cooled, passed through a catalytic converison stage for converting CO in to H2, and a converted synthesis gas having an H2 content, calculated in the dry state, of at least 55 vol.% and a CO content of at most 8 vol.% is extracted, that the converted synthesis gas is subjected to a multi-stage gas scrubbing process for removing CO2, CO and CH4, the synthesis gas being brought into contact with liquid nitrogen in at least one gas scrubbing stage and an N2/H2 mixture being produced which is fed to an ammonia synthesis stage for the catalytic production of ammonia. |
