Calgary-Agrium Inc. said Jan. 13 that it has entered into an exclusive agreement to supply Diesel Exhaust Fluid (DEF) grade prilled urea from its Borger, Texas, nitrogen facility for the production of DEF with Old World Industries, Northbrook, Ill. The privately held Old World is a leading manufacturer of antifreeze and is establishing DEF supply at a national level (GM Jan. 11, p. 12) with its BlueDEF-branded DEF. The tonnage supplied from the Borger facility will start from a small base and is expected to grow at a rapid rate over the next five-to-ten years. DEF will be added to the exhaust gas of most heavy-duty diesel engines made after Jan. 1, 2010. Agrium says the market for DEF across North America is expected to exceed 1.5 million tons of urea equivalent (1 billion gallons of DEF) by the year 2020. The Borger plant produces about 100,000 st/y of prilled urea, which goes into the feed market.
