Grannus LLC, Tucson, announced Nov. 2, that 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 its ammonia plant to be built in Kern County, Calif. (GM Oct. 14, p. 1). The plant is being built for the use of California Ammonia Co. (Calamco).
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, due up in 2019, will produce 250 st/d of ammonia, which the company says represents approximately 40 percent of California’s agricultural ammonia consumption.
