Construction of a new membrane electrolysis for Neolyse Ibbenbüren GmbH at AkzoNobel site Ibbenbüren

CAC has been awarded a contract by Neolyse Ibbenbüren GmbH - a production joint venture of Evonik and AkzoNobel - for the performance of EPCM services as general contractor for a new membrane electrolysis to be constructed at the AkzoNobel site in Ibbenbüren, Germany. The official signing ceremony took place on August 20th, 2015 already. The contract includes Detail engineering, procurement services, site management and commissioning support up to the performance test run of the plant.

The membrane electrolysis in Ibbenbüren will have an annual production capacity of 130,000 tons of caustic potash and 82,000 tons of chlorine. After the start of production, which is scheduled for the fourth quarter of 2017, AkzoNobel takes over the marketing of chlorine and hydrogen produced in the plant or will process those products directly at the Ibbenbüren site.

Evonik will take on the caustic potash for marketing and for further processing at the Evonik site Lülsdorf. In Lülsdorf, Evonik processes caustic potash, among other.

Licensor for the electrolysis technology will be Asahi Kasei Chemicals, Japan, which already was the technology partner of CAC for various projects, such as in Russia and Austria. Ashai Kasei Chemicals was also responsible for the provision of the membrane technology to the AkzoNobel sites in Delfzijl and Rotterdam.

The conversion of the existing mercury-based plant to the energy-efficient membrane technology will increase the efficiency and environmental sustainability and ensure compliance with future legal requirements.

"Our long-standing experience in the construction of chlor-alkali projects, our current references for plants producing caustic potash and the successful performance of the Basic Engineering were key to the decision of Evonik and AkzoNobel to entrust us with the construction of the plant on the basis of an EPCM contract", reports Jörg Engelmann, Chairman of the Board of Management at CAC.
