Abstract
An ammonia synthesis system 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 supplied to the ammonia synthesis unit has an ammonia gas concentration of 3% by volume or more. A method for producing ammonia includes reacting nitrogen and hydrogen using a circulated gas having an ammonia gas concentration of 6% 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. The ammonia synthesis system and ammonia production method have a reduced energy requirement.
