Resumen de: WO2026024621A1
An integrated blue-green ammonia process that avoids the need for air separation is disclosed. Water electrolysis, to produce hydrogen, produces oxygen as a co-product. Natural gas (methane) is reacted in a reformer with steam and air to create a mixture composed primarily of hydrogen, steam, nitrogen and carbon dioxide. The oxygen from electrolysis drives this process, either directly inside an autothermal reformer, or indirectly by oxycombustion in the furnace of a steam methane reformer. The steam is removed by cooling the gas, the carbon dioxide is removed, leaving a purified stream comprising hydrogen and nitrogen. This stream can be combined with additional hydrogen from the electrolyzer to yield a 3:1 mixture of hydrogen and nitrogen for the Haber-Bosch process to make ammonia. The disclosed blue-green process is two-fold less expensive than the conventional green ammonia process and emits about half as much greenhouse gas as the conventional blue ammonia process.
