In this cooperation, the 2 companies complement each other through Kuehni‘s many years of experience in the field of stirred extraction columns and generally in the pilot technique and Sulzer‘s know-how in the area of structured packings. The customers can now be provided with new, extensive possibilities for solutions for their technical separation tasks with packed extraction columns. The plants designed are based on the results of pilot tests and with the help of an existing large-scale database. Through this collaboration, technically and economically optimized designs for all liquid-liquid extraction tasks are now available to the customer.
