Air Liquide Global E&C Solutions, the engineering and construction business of Air Liquide group, will license technology and provide engineering services for the production of hydrogen at Grannus’ regional-scale advanced ammonia plant to be built in Kern County, California.

The Grannus plant features a patented, ultra-low NOx emission natural gas to ammonia process. Air Liquide Global E&C Solutions will license oxygen-based Lurgi GasPOX technology  and associated gas clean-up technologies, including a pressure swing adsorption unit (PSA) to produce high purity hydrogen required for the ammonia process. In addition, Air Liquide Global E&C solutions will prepare process design packages (PDPs) for the natural gas to hydrogen process.

The Grannus plant is expected to operate below all applicable California air quality control standards. This will be the first ammonia plant to be built in California in more than 60 years and will be operational in 2019. The Grannus plant will produce 250 tons of ammonia per day, which represents approximately 40% of California's agricultural ammonia consumption. The regional scale design will provide farmers with local supply, at the same time allowing them to reduce transportation costs and associated risks.

Grannus' revolutionary plant concept and manufacturing design produces nitrogen fertilizer and generates power while emitting virtually no criteria air pollutants. Combining partial oxidation (POX) combustion, power generation and near zero emissions, Grannus' next generation plants reduce natural gas consumption over leading state-of-the-art plants allowing for reduced operating costs.
