Your ammonia growth, grounded in our nitrogen experience!
The challenge
Ammonia is one of the key building blocks widely used in fertilizers and various industrial processes. Its role, however, is rapidly evolving. As a highly efficient hydrogen carrier, ammonia is becoming a key enabler in the energy transition, particularly for decarbonizing hard-to-abate sectors. Meanwhile, the global demand for ammonia is expected to rise significantly.
The question isn't whether consumption will grow, but whether it will grow in line with the global population and economic expansion or accelerate even faster as it becomes an indispensable component of the low-carbon economy.
The Solution
With over 75 years of expertise in nitrogen fertilizer technologies, Stamicarbon offers trusted solutions for efficient and scalable ammonia production. Our ammonia technologies portfolio includes two distinct designs, each tailored to specific project scales, feedstock types, and sustainability goals.
Whether your priority is small-to-medium scale production from renewable electricity or large-scale ammonia from fossil sources with carbon capture integration, we have the solution to match your needs.

NX STAMI™ Ammonia at a Glance
NX Stami™ Ammonia offers medium and high-pressure technologies for small to large-scale ammonia production. These technologies cover 50-500 and 50-3500 MTPD ammonia, using renewable electricity (solar/wind/hydro/geothermal), as well as renewables or fossil fuels with carbon capture utilization and storage.
The high-pressure design is modular with small footprints, and the medium-pressure design supports efficient ammonia production at a low cost. These technologies are suitable for decentralized production of green ammonia or large-scale production, e.g., integrated into major fertilizer complexes.
Solutions for Large Capacity Ammonia Plants
To meet the growing demand for low-cost and high-efficiency ammonia production, Stamicarbon offers the NX STAMI™ Ammonia Medium-Pressure Design.
Designed for capacities ranging from 50 to 3,500 MTPD, and scalable to even larger sizes, this process provides flexibility to match specific customer needs.
With more than 45 industrial references, NX STAMI™ Ammonia Medium-Pressure Design is a proven and cost-effective solution for conventional ammonia production.
NX STAMI™ Ammonia Medium-Pressure Design features a multi-bed, radial-flow reactor with a low-pressure drop configuration. This has been optimized to allow high per-pass conversion with the minimum possible catalyst volume and can be customized based on operating variables.
The system is notable for its superior temperature control in the first bed, allowing for a more efficient converter operation and a longer expected catalyst lifespan.
Green Ammonia Production
To enable ammonia production from renewable energy sources with minimal environmental impact, Stamicarbon also offers the NX STAMI™ Ammonia High-Pressure Design, focusing on sustainable ammonia production.
Designed for small- to medium-scale green ammonia plants with capacities from 50 to 500 MTPD, this technology features a modular setup and compact footprint, making it ideal for decentralized applications.
Operating with a single reciprocating compressor minimizes equipment requirements and delivers substantial CAPEX savings.
With four plants already in operation, NX STAMI™ Ammonia High-Pressure Design has the most substantial reference base in the sub-500 MTPD segment, more than any other licensor.
The ammonia synthesis loop operates at a high pressure, increasing conversion efficiency while reducing the need for costly refrigeration systems. The ammonia converter used in this process features a single axial flow catalyst bed design. Heat exchange tubes submerged in the catalyst bed allow excellent temperature control, preventing adverse effects such as catalyst sintering.
The process flow begins with make-up gas, a mixture of hydrogen and nitrogen from an upstream electrolyzer and nitrogen generation unit. This gas is compressed in an electrically-driven reciprocating compressor to over 300 bar, and the recycle stream also recompressed to the same pressure.
The high-pressure synthesis loop allows single-stage ammonia condensation using cooling water, eliminating the need for a refrigeration compressor.
FAQ
How can I produce ammonia with the highest efficiency?
NX STAMI™ Ammonia technologies are designed for optimization. They are cost-effective, with competitive pricing across all plant sizes.
