  • Patent number: 11084731
    Abstract: A process for preparing ammonia or ammonia and urea in a facility may involve compressing a crude synthesis gas stream that includes hydrogen, nitrogen, and carbon dioxide, washing a substream of the crude synthesis gas with ammonia to form a purified synthesis gas stream depleted of carbon dioxide and a condensate, synthesizing ammonia from the purified synthesis gas stream, and synthesizing urea from the condensate to form an aqueous urea composition. In the preparation of ammonia and urea, the crude synthesis gas stream may be, after being compressed, divided into a first synthesis gas substream and a second synthesis gas substream. In some instances, only the first synthesis gas substream is scrubbed with liquid ammonia.
