MANUFACTURING AND SERVICE FACILITIES
Cognis Ireland, Ltd. produces LIX Reagents in two, state-of-the-art plants using our patented production processes.
Production facilities for Cognis’ Alamine® and Aliquat® solvent extraction reagents are located in Kankakee, Ill.
NEW PRODUCTS AND SERVICES FROM COGNIS
First, Cognis has announced its line of LV or Low Viscosity copper solvent extraction reagents. This line includes both non-modified and modified oximes, and all continue to be Low Density reagents. Both of these properties facilitate phase separation, reduce entrainment, and allow the use of LIX® Reagents up to 50 volume percent in the organic phase.
Next, Cognis is pleased to announce its Opti-Form optimum formulation software. This software allows Cognis engineers to analyze each and every solvent extraction circuit (PLS, pH, sulfate content, stripping conditions, staging requirements, etc.) and formulate the optimal blend of oximes and modifiers.
Next, Cognis announces its ‘Flexible Circuit’ and ‘Optimum Series-Parallel’ solvent extraction circuit flow sheets. Both can provide savings in capital and operating costs when compared to convention circuit designs.
Finally, Cognis announces its latest version of Isocalc® TM isotherm and McCabe-Thiele modeling software. This latest version takes advantage of the many formulations available from Cognis and it will accurately model the new Optimum Series-Parallel circuits.
