Unipar will replace the existing mercury and diaphragm plants with electrolyzers featuring Thyssenkrupp Nucera’s highly efficient BM2.7 technology membrane technology.

The R$1 billion project is expected to be completed by the end of 2025.

The Thyssenkrupp Nucera 2.7v6 bipolar membrane (BM) allows very high energy and CO2 emission savings and guarantee a production capacity of 210,000 tons of chlorine per year. Unipar will reduce its CO2 emissions by 70,000 tons per year, as well as generate less solid waste, consume less energy (steam and electricity) and simplify operations on site.

Thyssenkrupp Nucera will also provide engineering, equipment and consulting services during the plant’s erection and commissioning.

“The modernization of our plant is a measure of enormous importance for us in strengthening our market position. Reliability, efficiency, and energy savings due to the chlor-alkali technology used are of immense importance. By using state-of-the-art BM2.7 technology, we can achieve these important targets,” says Rodrigo Cannaval, Industrial Executive Director at Unipar.

The Brazilian chemical group and Thyssenkrupp Nucera have worked together for many years. Unipar already uses BM 2.7 technology in other plants in Brazil.

“Unipar is relying on our proven BM2.7 technology for the very important modernization of its plant in Cubatão, which will enable our customers to achieve high energy savings. This marks the beginning of another chapter in our successful cooperation on their successful chlor-alkali plants,” says Dr Gerhard Henssen, Managing Director of thyssenkrupp nucera Italy SRL.
