The Port Neal Complex contains an ammonia plant, two urea plants, two nitric acid plants and a UAN plant.

The ammonia plant was built in 1966 and 1967. Its original rated capacity was 600 tons of anhydrous ammonia per day. Two major engineering projects increased the plant's capacity to 1,000 tons per day by 1992. Since the rebuild of 1995, the plant's capacity has been 1,150 tons per day.

Port Neal's Urea I and II plants were built in 1967 and 1973, respectively. In 1978, work on the second half of the Urea II plant was completed, which allowed us to produce urea liquor. Urea is used in various agricultural and industrial markets. Port Neal has the capacity to produce 1,075 tons of urea per day and 160 tons of urea liquor per day.

Port Neal's Nitric Acid plants are called the Acid I and Acid II plants. They were built in 1967 and 1997. Nitric Acid is a commercial chemical that is used as a building block in the production of UAN solutions. Port Neal has the capacity to produce 840 tons per day of nitric acid.

The Port Neal UAN plant was built in 1995 and can produce up to 2,400 tons of UAN per day. The 1995 rebuild helped establish the Port Neal plant as a state-of-the-art manufacturing facility. In addition to having excellent physical facilities, Port Neal follows stringent safety, environmental and maintenance procedures that contribute to impressive operational results.

Most of the ammonia that Port Neal produces is upgraded into UAN solution. UAN has been the fastest growing nitrogen product over the past decade because of the versatility it provides growers. UAN can be applied effectively in a variety of soil conditions and is especially useful in various conservation tillage practices. Due to lighter soil types and rolling terrain, the western Corn Belt is prime territory for such practices. Thus, the location of Port Neal and its UAN product line are ideal for growers in Iowa, Nebraska, South Dakota, Minnesota, and Missouri. The vast majority of the plant’s output is marketed in this five-state region.
