KBR offers conventional ammonia process technology in which our well-known, top-fired steam-methane primary reforming technology is combined with ammonia synthesis in a horizontal ammonia synthesis converter over a promoted iron magnetite or wustite catalyst at pressures of 140 to 170 bar.
Having a long history of well over 50 years that includes building more than 200 plants and successfully optimizing the energy consumption of this well-established process is what separates KBR from our competitors.
KBR employs its well-proven top-fired steam-methane primary reformer operating at high pressure coupled with secondary reforming using the stoichiometric amount of process air to efficiently convert natural gas into hydrogen and carbon oxide syngas.

For conventional magnetite ammonia synthesis loops, KBR offers its horizontal ammonia synthesis converter. The converter contains two or three reactor stages, each with vertical downward flow in the magnetite catalyst beds, which may be arranged as two beds in parallel depending on plant capacity. Intercoolers are provided between the reactor stages for maximum conversion and heat recovery.
