AkzoNobel Specialty Chemicals to upgrade Rotterdam chlor-alkali plant

The new production line, which is due for completion by 2021, will ensure a continuous supply of chlorine, including when one line is undergoing maintenance. It also enables the company to expand production capacity in the future to accommodate further demand growth. The Rotterdam plant is at the heart of an important industrial cluster for several essential chlorine derivatives including PVC, epoxy resins and polyurethane.

“Chlorine and caustic soda are essential raw materials for products ranging from pharmaceuticals to lightweight products such as epoxy resins used for wind turbines,” said Knut Schwalenberg, Executive Committee Member responsible for Industrial Chemicals. “To safeguard a continuous supply in the future and to further improve safety and sustainability, we plan to turn our site in Rotterdam into the most advanced chlorine plant in the world.”

The ‘e-flex’ technology, implemented this month, uses data analytics to automatically adjust chlorine production levels in line with changes in electricity supplies and thus optimize costs. Using flexibility – both in chemical production and electricity generation – will also help energy providers to balance large swings in supply from renewable sources such as wind power.

Werner Fuhrmann, CEO of AkzoNobel Specialty Chemicals, said: “The upgrades at our Rotterdam site will safeguard our position as a trusted partner for our customers, who rely on us to support the growth of their business. Taking advantage of digital technologies such as ‘e-flex’ also shows that digitalization, business growth and a sustainable future can go hand in hand.”

The Rotterdam site has the biggest single-line electrolysis unit in Europe, with a production capacity of over 630,000 tons per year of chlorine, as well as caustic soda and hydrogen. The company is currently preparing the permitting documentation for the new facilities and construction is expected to start in 2019.
