Ammonia & Fertilizer
As a leading supplier of ammonia process technologies, KBR has been involved in the licensing, design, engineering and/or construction of more than 200 ammonia plants worldwide, representing approximately half of current global ammonia production.Licensed KBR ammonia process technology solutions for the ammonia and fertilizers market include:
- Conventional Magnetite Ammonia Synthesis Process. Combines our top-fired primary reforming technology with ammonia synthesis in a horizontal ammonia synthesis converter.
- Purifier™ Ammonia Process. Our cryogenic syngas purifier along with a horizontal ammonia synthesis converter.
- PURIFIERplus™ Ammonia Process. Combines proven and reliable technologies from our proprietary KRES™, Purifier™ and horizontal ammonia synthesis converter.
- KBR Advanced Ammonia Process (KAAP™). Combines Top-Fired Steam Methane Reformer (SMR) with a KAAP Synthesis Converter.
- KAAPplus™. Combines the advantages of three KBR ammonia technologies: KRES™, Purifier™, and KAAP™.
Commercially-proven KBR proprietary ammonia process equipment solutions include:
- Top-Fired Steam Methane Reformer (SMR)
- KBR Reforming Exchanger System (KRES™)
- Purifier™ (cryogenic syngas purification)
- KBR Waste Heat Boiler
- Horizontal Ammonia Synthesis Converter
- KAAP™ Ammonia Synthesis Converter
- Unitized Chiller
In an ammonia plant, the synthesis gas is purified and the hydrogen to nitrogen ratio is adjusted to the stoichiometric 3:1 molar ratio needed for ammonia synthesis. Hydrogen, of course, can be recovered separately from the syngas mixture and purified to yield a high-purity hydrogen product stream for use in refinery processing units or petrochemical plants. In fact, KBR has worked on the design and/or construction of over 34 low-energy, low-cost refinery hydrogen plants using proprietary KBR natural gas reforming technologies. The innovative, cost-effective synthesis gas (syngas) production technologies and hydrogen production technologies KBR offers include: the KBR top-fired steam methane reformer (SMR) and the KBR Reforming Exchanger System (KRES™).
As a leading ammonia licensor, KBR has completed more than 40 projects for major fertilizer complexes, including production of ammonia, urea, nitric acid, ammonium nitrate, UAN solution, NPK, triple superphosphate, single super phosphate, di-ammonium phosphate, sulfuric acid, and ammonium sulfate. KBR has executed 62 urea projects and offers complete urea plant designs with plant capacities ranging from 600 to 3500+ mtpd. Most of the iear plant projects use Stamicarbon's urea technology. Stamicarbon is the leading licensor of urea process technology and KBR is authorized to license Stamicarbon's urea process technology to clients.
To enable our clients to extract the maximum possible performance from their KBR-designed ammonia plants, we offer advanced process automation technologies that include Advanced Process Control Systems and Operator Training Simulators.
