Abstract
The ammonia synthesis system of the present invention includes an ammonia synthesis reaction unit that synthesizes ammonia from nitrogen and hydrogen; an ammonia cooler that cools an ammonia-containing gas discharged from the ammonia synthesis reaction unit; a gas-liquid separator that separates ammonia liquefied by the ammonia cooler from a circulated gas; and an ammonia synthesizing gas supplying unit that supplies nitrogen gas and hydrogen gas, the circulated gas being supplied to the ammonia synthesis reaction unit, the circulated gas supplied to the ammonia synthesis unit having an ammonia gas concentration of 3% by volume or more. The method for producing ammonia of the present invention includes reacting nitrogen and hydrogen using a circulated gas having an ammonia gas concentration of 3% by volume or more and using an ammonia synthesis catalyst under a condition of a reaction pressure of 10 MPa or less to produce ammonia.
