Construction on the anhydrous ammonia plant at the Great Plains Synfuels Plant began in mid-1995.
Anhydrous ammonia is commonly used in the agriculture industry as a fertilizer.
Here is an excerpt from a story written for Current, the employee newsletter, in August 1995:
Plans for the $80 million project began in March after Dakota Gasification Company’s board of directors approved the 1,000-ton-per-day addition. Equipment from a shutdown ammonia plant in Iowa was located and is being dismantled, reconditioned, transported and installed at the Synfuels Plant. The facility is scheduled to be on line by late summer of 1996.
DGC’s production of anhydrous ammonia will increase from 27,000 tons annually to 350,000 tons, with 15 percent to be used in the flue gas desulfurization unit — or scrubber — also under construction. The scrubber, which will remove sulfur dioxide from the main stack, will convert 50,000 tons of ammonia to 200,000 tons of ammonium sulfate annually to be sold as fertilizer. …
Mike Pontbriand (on-site construction manager) explains why teamwork is functioning so well. “We have a unique construction organization with DGC and Morrison Knudsen personnel working as a team to complete the ammonia project,” he says. “Our combined organization, known as the DGC construction gruop, working with the other DGC departments, has been extremely efficient in handling the day-to-day construction problems.”
