Grannus selects Haldor Topsoe for technology and services at California environmentally sustainable ammonia plant


TUCSON, AZ (Nov. 15, 2016) — Grannus, LLC, announced that Haldor Topsoe will license technology and provide engineering services for the production of ammonia at its regional-scale advanced plant to be built in Kern County, CA.

The Grannus plant features a patented, ultra-low NOx emission natural gas to ammonia process. Haldor Topsoe will license its ammonia loop, shift catalyst and sulfur guard technologies for the production of high purity ammonia. In addition, Haldor Topsoe will prepare process design packages (PDPs) for the hydrogen to ammonia 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 percent 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’ high efficiency plants reduce natural gas consumption over leading state-of-the-art plants allowing for reduced operating costs.

Matthew Cox, CEO of Grannus, LLC said, “Collaborating with Haldor Topsoe in the development and delivery of our first plant validates our technological innovation and will enable accelerated worldwide adoption due to their market leadership in ammonia technology.”

Henrik W. Rasmussen, Vice President Catalyst & Technology for Haldor Topsoe said, “We are excited about being selected by Grannus to provide all the catalysts for the plant as well as our well-proven and highly energy efficient ammonia loop technology. Grannus looked at various competing technologies and concluded that Haldor Topsoe had the best ammonia loop technology for this project.”

About Grannus
Grannus was formed in 2012 to develop and bring to market next generation ammonia fertilizer production process technology. Grannus’ patented process replaces the traditional steam methane reformer with a more efficient partial oxidation boiler. This novel process creates synthesis gas at the lowest emissions level in the industry at efficiency levels exceeding existing best-of-class plant designs. The company intends to increase plant capacity designs to ‘world-scale’ and expand into adjacent markets including hydrogen, methanol and other down-stream chemicals.
