The Yazoo City nitrogen manufacturing facility is located on approximately 2,240 acres in Yazoo County, Mississippi. The facility includes one ammonia plant, four nitric acid plants, an ammonium nitrate (AN) plant, two urea plants, a UAN plant and a dinitrogen tetroxide production and storage facility. It has the capacity to produce annually:
- 500,000 tons of ammonia, which we sell as a feedstock for upgraded nitrogen-based fertilizers and industrial products.
- 525,000 tons of UAN (32% nitrogen basis) for agricultural uses.
- 1,075,000 tons of AN, which we produce as a solid or liquid product. Ag grade AN is sold in solid form as a fertilizer. Industrial grade AN (IGAN) is a prilled, low-density product that is used by mining operations as a blasting agent. AN solution (ANS) is a liquid product used in mining and other industrial applications. Beginning in 2005, one of its Yazoo City AN towers was modified to equip the plant to convert ANS to either ag grade AN or IGAN to supply Orica USA Inc with ANS and IGAN. (Note that our full solid AN capacity is 850,000 tons, but that level of production would limit our UAN production to approximately 450,000 tons and increase urea production to 45,000 tons.)
- 100,000 tons of urea. Most of the urea produced at our facility is further processed into UAN. The remaining quantity, we sell as a finished product for use in industrial emissions abatement.
- 900,000 tons of nitric acid, most of which we use to make ammonium nitrate. We sell the rest as a finished product to industrial customers to make products such as nylon fibers, polyurethane foams and specialty fibers.
The sole purchased feedstock in nitrogen products manufacturing is natural gas. When operating at capacity, the Yazoo City facility consumes about 20 million MMBtu’s of natural gas per year.
Focus on Safety and Security
The Yazoo City facility workforce considers safety and security their top priorities. In support of those objectives, they:
- Conduct more than 100 “tailgate” safety meetings per month, which have contributed to a significant reduction in the frequency of accidents over time.
- Have beefed up their security force by maintaining a guardhouse 24/7, staffing a roving guard and employing an additional weekday guard.
- Have implemented an Ammonium Nitrate Safe Delivery Confirmation policy.
