The law stipulates that the production of potassium hydroxide solutions with the current mercury electrolysis technology must be phased out by 2018. The new membrane electrolysis will replace this procedure with an environmentally-friendly and sustainable method.
"This investment would allow us to reliably supply our customers with our potassium hydroxide solutions in the long term. At the same time, it would make an important contribution to the environmentally-friendly and sustainable production of potassium hydroxide solutions," explained Gregor Hetzke, Head of Evonik's Advanced Intermediates Business Unit.
The membrane electrolysis facility in Ibbenburen is to have a nominal annual capacity of approximately 130,000 metric tonnes of potassium hydroxide solution and a nominal annual capacity of approximately 82,000 metric tonnes of chlorine. After the startup of production, which is projected for the third quarter of 2017, AkzoNobel would take over the marketing of chlorine and hydrogen or process the substances directly at the Ibbenburen site.
Meanwhile, Evonik would take over the marketing and further processing of potassium hydroxide solution at its Lulsdorf site, where Evonik processes potassium hydroxide solution into potassium carbonate.
