We formed Rentech Nitrogen Partners, L.P. in 2011 to own, operate and expand our nitrogen fertilizer businesses. Rentech Nitrogen is structured as a Master Limited Partnership and is publicly traded on the NYSE under the symbol "RNF." Rentech owns approximately 60% of Rentech Nitrogen and is the partnership's general partner.
Rentech Nitrogen's assets consist of two fertilizer production facilities owned by its operating subsidiaries. Rentech Nitrogen's East Dubuque Facility is located in the northwestern corner of Illinois, and uses natural gas as a feedstock to produce primarily anhydrous ammonia and urea ammonium nitrate solution for sale to customers in the Mid Corn Belt. Rentech Nitrogen's Pasadena Facility is located in Pasadena, Texas along the Houston Ship Channel. Rentech Nitrogen's Pasadena Facility is the largest producer of synthetic granulated ammonium sulfate fertilizer in North America, with sales in the United States and South America. The facility uses ammonia and sulfur as its primary feedstocks.
