A system (200) for producing ammonia includes a hydrogen gas source (208) and a nitrogen gas source (216), a hydrogen gas booster (210) for producing pressurized hydrogen gas, a nitrogen gas booster (218) for producing pressurized nitrogen gas, and a synthesis reactor (206) that receives a mixture of the pressurized hydrogen and nitrogen gases. The synthesis reactor (206) includes an inlet for receiving the pressurized gas mixture, a heating zone (232) adjacent the inlet for heating the gas mixture, a catalyst zone (234) downstream from the heating zone for catalyzing a reaction of the mixture to form ammonia and a by-product, and a cooling 'zone (236) downstream from the catalyst zone for cooling the ammonia and the by-product. The system has a separator for separating the ammonia from the by-product, an ammonia storage tank (228) for collecting the ammonia, and a recycle loop (230) for re-circulating the by-product back to the synthesis reactor. |
