The NaCl-ODC electrolysis process differs from the conventional membrane process which results in a reduction of the cell voltage from about 3 V to 2  V. Consequently, the ODC technology cuts the energy consumptionby at least 30%; or alternatively, at constant energy consumption, a corresponding capacity increase is possible. As a result, the ODC technology is ecologically valuable and supports clients’ sustainability. By saving energy, clients will indirectly realise significant CO 2 emission reductions. In conclusion At the close of our meeting, Vishal Harichund summed up the implications of these changes: “The successful conclusion of this latest joint venture is further indication of our commitment to supplying world class engineering and innova- tive solutions to our clients. The wide application of chlorine and caustic soda in pulp and paper, water treatment, inorganic chemicals, organic chemicals and detergents, along with a number of innovative target market products and services under development across the TKIS technology portfolio, strongly suggests that this industry presents attractive growth. “TKIS SA, the local organisation of our Germa- ny-based parent company, is well-positioned to of- fer this market cost-effective, high-tech solutions associated with an innovative EPC contractor.”

In the production of chlorine and caustic soda solution, ThyssenKrupp Uhde Chlorine Engineers energy-efficient and environment-friendly, ‘Uhde BMSingle Element’ membrane technology, as well as the BiTAC family electrolysers, are leaders. New plants as well as revamps or conversions, which together have a total annual capacity in excess of 40 million tonnes of caustic soda solution, provide ample proof of this. The new global setup will be rolled out over the months to come. An increased presence worldwide will be achieved by synergising the company’s worldwide capabilities for engineering, procure- ment and construction of high-efficiency electroly- sis plants, as well as offering leading technologies, comprehensive solutions, technical support and sales. Headquartered in Dortmund, Germany, the company is also represented in locations in Okayama, Tokyo, Shanghai, Milan and Houston. Invention that increases energy efficiency The NaCl-ODC electrolysis technology marketed by ThyssenKrupp Uhde Chlorine Engineers offers numerous benefits including, most importantly, a reduction of energy consumption of up to 30 % compared to conventional membrane-based tech- nology; ecologically valuable solutions because of corresponding CO 2 emission reductions; and full compatibility of electrolysis cells and the brine cycle, which allows for a combination of both technologies in one plant.
