Beschreibung
Zusammenfassung:	Disclosed is a urea production method and a urea production apparatus with which hydrogen and oxygen are generated by electrolysis of water in an electrolysis unit (E), nitrogen is separated from air and recovered in an air separation unit (A), ammonia is synthesized in an ammonia synthesis unit (N) using the hydrogen from the electrolysis unit (E) and the nitrogen from the air separation unit (A) as starting materials, carbon dioxide is generated by combusting fuel in an oxygen combustion unit (O) using at least the oxygen from the electrolysis unit (E), and urea is synthesized in a urea synthesis unit (U) using the carbon dioxide and ammonia as starting materials.
