KMPS offers a wide range of extraction columns, from
static columns containing trays or packing, to agitated columns including Scheibel, Karr, Pulsed and
Rotating Disc Contactors (RDC).
Each
of the columns has particular strengths and weaknesses, which must be taken
into consideration to ensure the proper extraction device is selected.
Often 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. |

- 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 2" 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. |
