AkzoNobel selects ThyssenKrupp Uhde for chlor-alkali electrolysis technology

AkzoNobel Industrial Chemicals has commissioned ThyssenKrupp Uhde to design and supply the energy-saving ThyssenKrupp Uhde membrane cells for the conversion of the mercury based electrolysis plant at the Industry Park Frankfurt-Höchst into state-of-the-art membrane electrolysis technology.

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 in Frankfurt by around 50% to 250,000 tonnes of chlorine and 275,000 tonnes of caustic lye. Commissioning is scheduled for the fourth quarter of 2013.

“The electricity consumption per ton of product will be improved by nearly 30%”, said Martin Riswick, General Manager of AkzoNobel’s Chlor-Alkali business, “This is fully aligned with AkzoNobel’s Value and Values strategy and will boost our ambition to become the sustainability leader in the chlor-alkali industry”.

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. "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.
