Ammonia & Fertilizers Technologies

Ammonia and fertiliser plants face many challenges, from securing feedstocks at favourable prices to reducing the costs of products. KBR delivers the technologies they need to keep their operations competitive.

We’ve been a premier partner for the ammonia and fertilisers industry for more than 50 years, providing the superior technologies and solutions to optimise production, reduce capital costs, and ensure reliable, efficient and flexible operation. From ammonia and nitric acid to UAN, we work with you to deliver the solution that suits your needs — and the needs of the market.

“From ammonia and nitric acid to UAN, we work with you to deliver the solution that suits your needs — and the needs of the market. ”

With our considerable experience designing, building and maintaining ammonia and fertiliser facilities of all kinds, we’ve developed the expertise and understanding essential to solving any challenge. And we help operators to maximise production through our licensed and proprietary technology solutions, including:


Our optimised cryogenic synthesis gas technologies that simultaneously remove impurities such as methane and argon to produce inert-free synthesis gas, offer greater energy efficiency, and are designed to use air rather than pure oxygen in the reforming section of the plant, eliminating the need for additional expensive equipment.

Ammonia 6000®

Complete, single-stream ammonia plant solution based on our proprietary PURIFIER™ technology that expands capacity to 6000 MTPD while using proven and reliable designs, reducing CAPEX, OPEX, and emissions of CO2 and NOx.

Conventional Ammonia Synthesis Process

Proven technology for ammonia production, combining top-fired primary reforming technology with ammonia synthesis and providing optimised energy consumption based on our unique and extensive experience with these solutions.


KBR’s green ammonia process achieves low or zero greenhouse gas emissions by combining our unsurpassed ammonia synthesis plant reliability, with lower energy consumption at lower capital cost (due to lower equipment count) with state of the art electrolysis and air separation sections. The KBR design of the complete green ammonia facility incorporates a high level of operational flexibility, particularly in the electrolysis section with optimum intermediate buffering of hydrogen, allowing continuous operation of the synthesis section, in order to optimise capital costs and the value of intermittent renewable power supplies.

Nitric Acid

High mono-pressure and proprietary dual-pressure technologies developed to be energy- and cost-efficient while ensuring high ammonia conversion for facilities with a wide range of production targets.

Ammonium Nitrate

Our proven ammonium nitrate solution with an outstanding safety record uses a simple atmospheric plant design that offers a low total installed cost and precise pH control in the neutraliser, a packed section of the ammonium nitrate and vent scrubber operating in condensed mode, and filters to capture sub-micron ammonium nitrate mist for superior emissions performance.

Urea Ammonium Nitrate (UAN)

Complete integrated facility design combining urea, ammonium nitrate, nitric acid and UAN that provides efficient and cost-effective production of UAN solution. Patented partial-recycle urea process that results in higher overall raw material yields compared with non-integrated processes.


A portfolio of proprietary hydroprocessing technologies and equipment that produces hydrogen from natural gas, heavy naphtha and other feedstocks. Includes our top-fired steam methane reformer, KRES™ reforming exchanger system, and aerothermal reformer.
