WHAT WE DO

THE GRANNUS PROCESS

Grannus’ technology is used to build near zero emission, exothermic cogeneration power plants that produce synthetic gas for the manufacture of chemical byproducts. This technology integrates a partial oxidation gas boiler with the water gas shift process to make high hydrogen synthetic gas with a near 3:1 ratio of hydrogen to carbon dioxide. With separation of the nitrogen, hydrogen and carbon dioxide streams, excess power and steam, the building blocks exist to make other chemicals with controlled ratios, such as Haber-Bosch ammonia, Bosch-Meisner urea, or Fischer-Tropsch gas to liquids.

 

The Grannus process offers many advantages to traditional fertilizer manufacturing by utilizing 100% of plant emissions for the production of fertilizer combined with strong cogeneration capabilities thereby reducing overall power usage. This paradigm shift allows the design and construction of green, zero-emissions thermal power plants in an otherwise uncertain permitting and political atmosphere; while also competitively reducing the cost to make fertilizer locally.

WHY GRANNUS?

THE GRANNUS ADVANTAGE

  • Reduction in natural gas and electricity usage resulting in production cost advantage
  • Construction cost per ton at or below plants 3X the capacity
  • Virtually no emissions (requires no Title V air or PSD permit and no federal Environmental Impact Study)
  • Two-year Construction Schedule, local permitting of 6 to 10 months
  • Sizing is ideal for financing and supply of regional ammonia or urea demand off take for local utilities and co-ops
  • Requires minimal cooling water and can use air cooled condensers aspects
