Chemnitz/Germany – The new plant is based on the modern, energy-efficient and environmentally friendly membrane electrolysis process of Asahi Kasei Chemicals, Japan. In about two years, after its completion, the plant will replace the mercury-electrolysis plant, which was shut down in 2017.

With an expected production capacity of 68,000 tons a year of chlorine, CUF, Portugal’s largest chemical company, intends to strengthen its leading position in the Iberian market for chlorine and chlorinated derivatives.

In addition to the membrane electrolysers based on technology from Asahi Kasai, the scope of services and supplies includes brine preparation (filtration, softening, iodine removal, ammonia removal), caustic evaporation as well as a sodium hypochlorite unit.

CAC is responsible for basic and detailed engineering, procurement of all equipment and bulk materials, construction and installation services, construction and installation supervision as well as advisory services during commissioning.

At the end of 2017, CUF acquired parts of the chlorine factory in Torrelavega from the international chemical group Solvay and is investing €55 million in these production facilities as well as in the construction of the modern chlor-alkali electrolysis plant.
