Resumen de: AU2024399298A1
The invention relates to the synthesis of urea from ammonia and carbon dioxide, wherein the hydrogen required for ammonia synthesis is obtained both by steam reforming of feed natural gas (grey hydrogen) and by electrolysis of water using electricity from renewable energy sources (green hydrogen). As the proportion of green hydrogen increases, the amount of carbon dioxide formed in the synthesis gas during steam reforming is no longer sufficient for the synthesis of urea. Therefore, flue gas, which is formed during the combustion of a fuel gas composed of fuel natural gas and combustion air and which also contains carbon dioxide, is additionally used. The oxygen formed during the electrolysis of water is introduced into the flue gas, and the modified flue gas is fed to a secondary reformer; and/or the fuel natural gas is combusted together with combustion air and the oxygen formed during electrolysis. Excess nitrogen is preferably separated from the synthesis gas before it is used for the synthesis of ammonia.
