ThyssenKrupp EPC contractors Uhde have supplied and commissioned a 3500 tonnes per day urea production plant in Sluiskil, Netherlands, for Yara of Norway. For the plant, which took three years to build, Yara has invested EUR 400 million.
Dortmund, Germany – The technology was licensed by the Dutch company, Stamicarbon. ThyssenKrupp Uhde was responsible for the engineering, supply of all equipment and the construction of the plant on a fixed-price, turnkey basis.
According to Uhde, the plant meets the latest environmental standards as well as best available technology standards. There are even special collection systems which, should the plant malfunction, ensure that no hazardous substances escape into the environment.
Some of the urea the plant produces will not be used as fertiliser but as an aqueous urea solution to treat diesel exhaust fumes. This technology reduces NOx emissions. This urea solution is now being sold at service stations, for example, and is marketed by Yara under the name of Air1. It enables the latest models of commercial vehicles to achieve the maximum permissible limit values specified in Eurocode 5 and in a few years time Eurocode 6. The required feedstocks are ammonia and carbon dioxide, which are both available at the site in Sluiskil. The urea plant will obviate the need to transport the ammonia and the CO2 that is generated will be used in an environment-friendly manner.
