Commissioning of first large-scale plant for climate-friendly chlorine production

In March 2010 Uhde GmbH (Dortmund, Germany; www.uhde.eu) and Bayer MaterialScience (Leverkusen, Germany; www.bayermaterialscience.de) signed a contract for the construction of a new chlorine plant at the Chempark Krefeld-Uerdingen site. This 20,000-metric-ton per year chlorine demonstration plant has now come on-stream. The oxygen-depolarized cathode used for this has been incorporated into the new single-element technology from Uhde/Uhdenora. With the introduction of this new industrial manufacturing process the two companies involved are hoping to significantly reduce energy consumption and CO2 emissions. The combination of the two technologies was developed at Bayer in Leverkusen over the past eight years. Provided the two-year large-scale trial is successful, Bayer will gradually switch its chlorine production to the new process. In addition, the companies also intend to offer the new technology on the global market from 2013 onwards. Major German chlorine producers have already announced their interest, as have a number of companies in the Asia/Pacific region. ”We are proud of our long partnership with Bayer MaterialScience,” says Alfred Hoffmann, member of Uhde’s executive board. “As a technology-driven…
