Covestro implements first plant based Oxygen-Depolarized Cathode Technology
Covestro is investing around $ 231.7 million at Tarragona in Spain to increase the site’s competitiveness. The new chlorine production plant is a key component of that. About one third of the production costs for chlorine are usually spent on energy. Thus, the selected technology makes an important economic contribution.
Construction of the new plant in Tarragona is scheduled to begin in the first half of 2019. Chlorine is mainly needed at Tarragona to make MDI. MDI is a precursor for rigid foam, which is an excellent insulation material and is used, for example, in buildings and refrigerators to reduce their power consumption. Compared with the conventional method, it cuts CO emissions by around 2 22,000 metric tons per year.
