    摘要: 1. IN A PROCESS FOR SYNTHESIZING AMMONIA AT HIGH PRESSURE FROM A FEED GAS STREAM CONTAINING HYDROGEN AND NITROGEN, THE STEPS COMPRISING PASSING SAID FEED GAS STREAM IN HEAT EXCHANGE RELATIONSHIP WITH A PARTIALLY SYNTHESIZED GAS HAVING A TEMPERATURE FROM ABOUT 800 TO 1100*F. TO INCREASE THE TEMPERATURE OF SAID FEED GAS STREAM TO ABOUT 650-800*F. AND REDUCE THE TEMPERATURE OF SAID PARTIALLY SYNTHESIZED GAS, PASSING SAID HEAT EXCHANGED FEED GAS STREAM DIRECTLY FROM SAID HEAT EXCHANGE STEP TO A SYNTHESIS CONVERTER AND SUBJECTING THE SAME TO SYNTHESIS CONDITIONS TO PRODUCE PARTIALLY SYNTHESIZED GAS, AND THEREAFTER PASSING SAID HEAT EXCHANGED PARTIALLY SYNTHESIZED GAS DIRECTLY FROM SAID HEAT EXCHANGER TO A SYNTHESIS CONVERTER AND SUBJECTING SAID PARTIALLY SYNTHESIZED GAS TO FURTHER SYNTHESIS THEREIN.

    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.
