As of February 1, the Swiss firms Sulzer Chemtech Ltd. (Winterthur; www.sulzerchemtech.com) and Kühni AG (Allschwil; www.kuhni.ch) will work closely together in the field of extraction. The goal of this co-operation is to develop comprehensive solutions for the complex task of packed liquid-liquid extraction (LLE) columns, from pilot tests to industrial realization.
The co-operation takes advantage of the complimentary strengths of the two companies, including Kühni’s experience in the field of stirred-extraction columns and pilot techniques, and Sulzer Chemtech’s know-how in the area of structured packings. Kühni has been active in the field of liquid-liquid extraction for over 45 years, and with over 500 references, the firm is especially recognized in the area of stirred extraction columns. Sulzer Chemtech has more than 25 years of experience in designing LLE columns. Its SMV/SMVP technology is successfully applied in over 300 operating extraction columns.
Customers can now be provided with new, extensive possibilities for solutions for their technical separation tasks with packed extraction columns. The designed plants are based on the results of pilot tests as well as data from existing large-scale applications. Through this collaboration, both technically and economically optimized designs for all LLE tasks are now available.
