BiTAC & BM 2.7: Proven Chlor-Alkali Electrolysis technologies

thyssenkrupp Uhde Chlorine Engineers has been active in the chlor-alkali sector throughout the world for more than 50 years. During this time we have progressed from mercury and diaphragm plants to modern, environment-friendly membrane plants, which now account for nearly all of the total 40 million mtpa of NaOH (100 %) produced by the plants we have built.

Depending on the customer’s wishes, we offer to construct new plants, to expand existing ones or convert mercury or diaphragm plants to membrane technology.

With more than 300 highly skilled, experienced engineers at our company you can be sure that our electrolysis plants are of the highest quality. We provide an extensive range of supplies and services to cater for the diverse needs of our customers – whether it’s a large lumpsum turnkey project or a feasibility study.

Throughout the chlorine history of our company, close cooperation with our customers has been the main focal point.

From the very beginning thyssenkrupp Uhde Chlorine Engineers has combined its own highly effective electrolysis cells with a thorough knowledge of the entire chlor-alkali production process. In fact, thyssenkrupp Uhde Chlorine Engineers is the only company in the world to combine the engineering and supply of equipment for the construction of a complete chlor-alkali electrolysis plant with the supply ofelectrolysis cells.

After the companys’ merger there are two chlor-alkali electrolysis technologies in thyssenkrupp Uhde Chlorine Engineers’s portfolio:

  • BM 2.7 Single Element and
  • BiTAC filter press.

thyssenkrupp Uhde Chlorine Engineers will continue to maintain and improve both technologies to satisfy clients’ needs.
