CHS announced Friday that it is proceeding with construction of a $3 billion plant northeast of Jamestown that will turn natural gas from North Dakota’s oilfields into nitrogen fertilizer for the region’s farmers.
CHS engineer Bart Gill, project director for the plant near the Spiritwood Energy Park, said CHS wants to use as many U.S. manufacturers as possible for components needed for the plant, but some of the parts it needs will have to be imported from Europe. Several of the components are very large, including a 500-ton ammonia converter.
“That’s the largest single piece of equipment that we’ll have, but we have several pieces of what we call oversized-overweight equipment that we’re going to have to transport into the site,” Gill said. “They’ll be moved first on the ocean, probably over to the port of Duluth, then transported by roads and/or rail if we can get rail, but more likely by road now to the site.”
Activists and community organizers may want to start organizing now.
By the way, some background:
The Haber-Bosch process raises the temperature of the chamber to 572 to 1,022 degrees and increases the air pressure to a range of 2,200 to 3,600 pounds per square inch. In comparison, the average psi at sea level on Earth is about 14.7 psi.
The chemical reaction in the chamber produces ammonia out of the nitrogen and hydrogen, and ammonia is the main ingredient in nitrogen fertilizers. The gases that don’t produce ammonia on the first pass are recycled again through the tank.
“(The ammonia) is further processed into urea and then the urea is further processed into UAN,” Schouvieller said.
UAN is a solution of urea and ammonium nitrate in water that becomes fertilizer. The ammonia also will be used to produce diesel exhaust fluid, used in cleaning diesel engines.
“(UAN) is a nitric acid, so basically they take the urea liquor and add water, and now you have a liquid that’s 28 percent nitrogen,” Schouvieller said. “It’s probably important to point out that ammonia is 82 percent nitrogen and urea is 34 percent.”
