Abstract
Methods and systems for producing ammonia, urea, and UAN are described herein. The methods can include providing a hydrocarbon feed stock and an oxygen-containing stream and reacting the hydrocarbon feed stock with the oxygen-containing stream to provide a syngas containing carbon dioxide and blue hydrogen. The methods can also include electrolyzing water to provide green hydrogen and blending the blue hydrogen with the green hydrogen to provide a blended hydrogen. The blended hydrogen can be introduced to an ammonia synthesis system to provide an ammonia product, which can be further processed to provide urea and/or UAN. The ratio of green to blue hydrogen in the blended hydrogen can be based on available green credits.
