Stamicarbon, the innovation and license company of MAIRE Group, has signed a license agreement with its customer in the USA to develop a basic engineering design package for a 450 MTPD green ammonia plant. The plant will be based on the state-of-the-art Stami Green
Ammonia technology and is expected to start up in 2026, producing green ammonia to be used as feedstock for nitrogen-based fertilizers.
Stami Green Ammonia enables environmentally friendly ammonia production by deriving nitrogen from the air and using hydrogen obtained by water electrolysis instead of the steam reforming of fossil fuels. As a result, this technology offers a sustainable and highly competitive alternative to conventional gray processes, paving the way for producing green fertilizers from renewable energy sources.
Urea industry processes take place at high temperatures and pressure, and ammonium carbamate is highly corrosive. Therefore, the high-pressure (HP) synthesis equipment and parts have to be manufactured from strong, light and corrosion-resistant materials. The solution is Safurex®, a super duplex stainless steel specially designed to eliminate corrosion in fertilizer plants.
