MOSCOW (MRC) -- Covestro has successfully started up a new world-scale facility for the production of chlorine in Tarragona, Spain, said the company.
It is the first world-scale production plant for chlorine based upon the highly innovative and energy efficient ODC (oxygen depolarized cathode) technology invented by Covestro and its partners. The new plant ensures an efficient, sustainable and independent supply of chlorine and caustic soda to MDI production in Tarragona. This will strengthen the European production network for MDI – a precursor for the manufacture of rigid polyurethane foam used to insulate refrigeration appliances and buildings. The 200 million euro investment has created 50 new jobs on site.
"The successful start-up of the new plant is good news, both economically and ecologically, for Covestro as well as for our site in Tarragona", said CEO Dr. Markus Steilemann. "The plant demonstrates how new technologies enable us to advance our vision of the circular economy and further reduce resource consumption while increasing the robustness and efficiency of our production network."
The new chlorine facility is the first industrial-scale plant in the world to use the innovative oxygen depolarized cathode technology (ODC). The technology has been developed by Covestro in collaboration with thyssenkrupp nucera. Compared to the currently predominant conventional chlor-alkali electrolysis, the new process requires a lower voltage, which results in energy savings of up to 25 percent. At the new plant in Tarragona, this can avoid up to 22,000 metric tons of CO2 emissions per year compared with existing processes – based on the energy mix at the start of construction planning in 2018. The new plant will thus make an important contribution to Covestro’s goal of being operationally climate-neutral by 2035.
We remind, Covestro and LANXESS are cooperating in the energy-intensive production of basic chemicals at their Lower Rhine sites in Germany and make them more climate friendly. LANXESS procures chlorine, caustic soda and hydrogen from the ISCC PLUS-certified sites of Covestro in Leverkusen and Krefeld-Uerdingen. With immediate effect, Covestro is manufacturing around one-third of the volume of products it supplies to LANXESS using energy from hydropower based on guarantees of origin.
