Energy-efficient and environmentally friendly neutralization and recycling of chemical residues


We started the implementation of the project in 2016. The fund won in the tender was used in the frame of construction of the new membrane cell chlorine plant, built in accordance with BAT (Best Available Techniques) requirements, resulting in the elimination of mercury from chlorine production and significant electricity savings, which is reflected in lower indirect greenhouse gas emissions. The main reason for establishing the new chlorine plant built as part of the investment is that according to an EU resolution the mercury cathode brine electrolysis technologies in chlor-alkali production shall be stopped by December 2017.


Previously, we used high specific amounts of chemicals and heat to decompose sodium chlorate in chlorine production, which can be reduced significantly with the help of a suitable catalyst. This type of technology was not available in the market before, therefore its elaboration called for a research and development (R&D) activity. Our researchers have found a solution to reduce contamination by optimizing the previous technological process and developing new procedures, which enables us to operate the system more efficiently and effectively.

To perform the R&D tasks for the catalytic removal of chlorate, we established a consortium made up of five members and we came up with a patentable process as a result of our joint work.

The non-quantifiable result of the project is a pilot plant set up specifically for research purposes. In addition, we have set up an R&D workshop where internal and visiting researchers have the opportunity to develop new technological processes.



The project was implemented within the framework of the Széchenyi 2020 program.
