Dortmund, Frankfurt am Main – At the Frankfurt-Höchst industrial estate, AkzoNobel is converting an amalgam electrolysis plant to the modern membrane process and has commissioned ThyssenKrupp Uhde to design and supply the energy-saving ThyssenKrupp Uhde membrane cells. This extensive conversion project involves replacing the existing amalgam cells with ThyssenKrupp Uhde single-element membrane electrolysers. The new plant will increase annual production capacity by around 50 percent to 250,000 tonnes of chlorine and 275,000 tonnes of caustic soda solution. Commissioning is scheduled for the fourth quarter of 2013.

"We are proud that our electrolysis technology is to be used at the Frankfurt-Höchst site, where the first Hoechst-Uhde membrane cell was once developed," said Dr. Sami Pelkonen, Head of ThyssenKrupp Uhde's Electrolysis division. ThyssenKrupp Uhde's scope of services will include the basic and detail engineering of the electrolysers, as well as their supply and supervision of the commissioning activities. "The energy consumption per ton of product will be improved by nearly 30 percent", said Martin Riswick, General Manager of AkzoNobel's Chlor-Alkali business.
