In the last two weeks, Grannus LLC has awarded two contracts for process design and technology licensing: the first for hydrogen production, and the second for the ammonia loop.

These replace the engineering contract announced earlier this year, and bring the “zero-emission” ammonia plant closer to reality – albeit with a revised start-up schedule.

Air Liquide will take care of the plant’s front-end: hydrogen production.

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.

And Haldor-Topsoe will be responsible for the ammonia production.

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.

These two new contracts, as I understand it, replace the previous contract with Amec Foster Wheeler, even though that was only announced ten months ago.

Amec Foster Wheeler’s scope of work includes engineering design and definition work utilising key process technology and equipment suppliers, as well as execution planning activities for the facility. Work has begun on the project and the plant is expected to be operational by Q4 2017.

Obviously the schedule has been kicked back since that press release went out in January 2016: construction hasn’t begun, and the plant won’t be operational in 2017. The revised estimate, 2019, seems far more manageable.

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.

More information about the Grannus plant and its technology, which produces hydrogen from natural gas using a partial oxidation process instead of the more common steam methane reformation, is in my Research Note for Kern County, CA.
