Port Neal Nitrogen Complex Expansion, Iowa, United States of America
New ammonia and urea units were constructed at the Port Neal Nitrogen Complex in Iowa, US, operated by CF Industries Holdings. Ground was broken for the $1.7bn expansion in May 2013, and the project was completed in December 2016.
Located along the Missouri River in the Port Neal Industrial Complex, the nitrogen facility is built on a 1,700-acre site. The complex is strategically located in the US Corn Belt and is approximately 15 miles (24.1km) away from Sioux City, Iowa. It can access the existing gas supply from the Rockies, mid-continent US and Canada and future supply from Williston Basin owing to the strategic location.
The latest expansion is aimed at supplying urea to the company's customer base in upper-Midwest area, as well as takes advantage of the available natural gas in North America.
The state of Iowa and Woodbury County committed to provide special incentives to support the expansion. Expected to boost the local economy, the project created 130 permanent jobs, 700 permanent jobs in related industries and 2,000 construction jobs.
Details of Port Neal Nitrogen Complex
The Port Neal Nitrogen Complex produces approximately 771,107t of nitrogen for agricultural and industrial sectors. The facility consists of an ammonia plant, two urea plants, two nitric acid plants and a urea ammonium nitrate (UAN) plant.
The product line includes anhydrous ammonia, urea liquor, urea ammonium nitrate (UAN) solutions and diesel exhaust fluid (DEF). The nitrogen complex added granular urea to its product line in 2016.
The products are transported by different modes of transport that include pipelines, railways and trucks.
Port Neal Nitrogen Complex expansion details
The expansion project is aimed at enhancing the annual capacity of the facility by 1.27 million tonnes (Mt) of nitrogen products. It also triples the facility's ammonia production and enables the production of granular urea.
The project involved the construction of an ammonia plant with a capacity of 2,200t a day (t/d), a urea plant with a capacity of 3,500t/d and a urea granulation unit with a capacity of 3,500t/d.
Iowa Fertilizer Company (IFCo) decided to construct a new nitrogen-based fertiliser production plant at Wever near the Mississippi River in Iowa, US.
As part of the expansion, a 630ft-long bridge was constructed along the Missouri River that connects the nitrogen complex to a collector well that is the main source of water supply to the new facility, ensuring year-round access to water even during calamities such as floods. The bridge and the well were constructed at a 50ft-wide site at an elevated height to ensure safety during floods.
The bridge contains steel pilings, concrete components and 27 bents. An additional 56 pipe piles were installed in different areas of the plant during the first phase of construction.
The general contractor for the Port Neal Capacity expansion project is Performance Contractors. They are responsible for concrete foundations, structural steel erection, pipe fabrication and pipe installation, equipment assembly and equipment setting, rotating equipment assembly and alignment, and boiler and furnace assembly.
ThyssenKrupp Uhde's business partner Uhde Corporation of America has been chosen to provide engineering and supply services for the project. The scope of work included the basic and detail engineering, procurement and supply services, and providing services during construction and commissioning.
CDI Corp has been selected to work on the engineering design services for the expansion project. The contractor provided engineering and procurement services for a water treatment facility, two new ammonia storage tanks and all civil site development activities.
New Orleans-based construction company Boh Bros won a contract bid in August 2014 for the construction of the project.
