System for producing ammonia wherein a gasifier is used to make synthesis gas to provide hydrogen to an ammonia reactor. An ion transport membrane assembly and optionally a cryogenic air separation are used to provide oxygen for a gasifier. The ion transport membrane assembly also provides high pressure nitrogen for use in the ammonia reactor.
