Diesel Exhaust Fluid (DEF)

Construction on a urea production facility is under way at the Great Plains Synfuels Plant. The project is slated for completion in the spring of 2017 when 1,100 tons of urea daily will be produced, with the ability to shift urea production to produce diesel exhaust fluid (DEF).

Available in 2017

Diesel Exhaust Fluid (DEF) is urea liquor, which is required, by law for, modern diesel engines for emissions control. It is injected into the exhaust stream to react with harmful greenhouse gases. DEF is a non-hazardous solution comprised of 32.5% urea and 67.5% de-ionized water. It has a slight smell of ammonia, similar to some home cleaning agents. DEF is used in by Selective Catalytic Reduction (SCR) technology to remove harmful NOx emissions from diesel engines.

  • Dakota Gas will have the capacity to produce 64 million gallons of DEF per year.
  • Dakota Gas will have approximately 1 million gallons of on-site storage.
  • Dakota Gas will have truck and rail loading operations.
  • Dakota Gas accommodates 24/7 plant access for customers.
  • Dakota Gas plans to start in the first quarter of 2017.
