Each of the columns has particular strengths and weaknesses, which must be taken into consideration to ensure the proper extraction device is selected. If necessary more than one type of extraction column is tested to help optimize performance.
During the pilot tests, the columns are run over a wide range of operating conditions, and separation performance is measured. In addition, observations on droplet formation and dispersion, coalescence, interface control, entrainment, and emulsion tendencies are also made. Test data and observations are then used with KMPS proven scale-up correlations to arrive at the optimum extractor design.
With nearly 50 years of LLE testing experience, KMPS has learned how to streamline the testing procedures, minimizing the time and amount of raw material required. This results in significant cost savings for our clients. When it is not possible to test in our Houston Pilot Plant, then KMPS can supply pilot scale columns for on-site testing at the client facility.
- Agitated Columns – Karr®, Scheibel®, RDC, Pulsed
- Static Columns – Packing, Trays, SMVP
- Column Arrangements – Simple, Fractional & Reactive Extraction
In a number of applications, liquid-liquid extraction must be tested at elevated pressure due to the temperature and the vapor pressure of the material handled. KMPS has available for rental a 1″ diameter KARR® Column and 3″ diameter SCHEIBEL® Column, both in 316SS construction. These columns can be sent to the clients facility for on-site testing, along with operating and engineering personnel.
