Pechiney-Ugine-Kuhlmann process
The Pechiney-Ugine-Kuhlmann process is a process for the industrial production of hydrazine through the oxidation of ammonia with hydrogen peroxide. It was developed in the early 1970s by Produits Chimiques Ugine Kuhlmann, the chemicals division of Pechiney-Ugine-Kuhlmann, and is now operated by Arkema at its Lannemezan plant in southern France.
Lannemezan plant
The Lannemezan plant, on the outskirts of the town of Lannemezan in the Hautes-Pyrénées départment of southern France, is the world's largest hydrazine hydrate plant,[1] producing 17,000 tonnes of hydrazine products per year.[2] It was founded in 1917 by the Poudrerie Nationale to produce calcium cyanamide, and was privatized in 1921 as the Société des Produits Azotés (SPA). The first hydrazine hydrate plant, based on the Raschig process, was installed by the SPA in 1962. The plant was overhauled in 1980 to install the new Pechiney-Ugine-Kuhlmann process.[2]
