    摘要： A horizontal, cold wall, multi-bed ammonia converter having two, shell and tube interchangers for cooling reaction gas streams leaving respectively the first and second catalyst beds with incoming reactant gases wherein each of the interchangers is vertically oriented and physically located between catalyst beds. The catalyst beds are adiabatic, slab-shape beds defined in part by side portions of the inner wall of the converter and are arranged for downward, transverse flow of reacting gases. Longitudinal conduits and baffling in cooperation with the arrangement of catalyst beds and interchangers provide serial flow of gas through the cold side of each of the interchangers, a first catalyst bed, the hot side of one of the interchangers, a second catalyst bed, the hot side of the other interchanger, a third catalyst bed, and, optionally, a fourth catalyst bed.

    摘要： The present invention is generally directed to an improved process and apparatus for the production of gaseous products such as ammonia by catalytic, exothermic gaseous reactions and is specifically directed to an improved process which utilizes a gas-phase catalytic reaction of nitrogen and hydrogen for the synthesis of ammonia. This improved process for the production of ammonia utilizes an ammonia converter apparatus designed to comprise at least two catalyst stages and a reheat exchanger so arranged as to provide indirect heat exchange of the gaseous effluent from the last reactor catalyst stage with the effluent from at least one other reactor catalyst stage having a higher temperature level in order to reheat the effluent from the last reactor catalyst stage prior to exiting the reactor vessel, thereby facilitating higher level heat recovery from the reactor effluent.

    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.
