The CINC Solutions’ liquid-liquid centrifuges operates both as separator and contactor, which makes it a valuable tool in numerous types of processes. Its unique, patented design provides mixing and separation in a single, compact unit.
Two immiscible liquids of different densities are fed to the unit and are rapidly mixed in the annular space between the spinning rotor and the stationary housing. The area above the liquid levels is vent area. For separation applications, a low-mix option is employed to reduce liquid shear in the annulus.
The CINC Solutions’ self pumping rotor is divided into four vertical chambers, which are dynamically balanced by the pumped liquids. Once trapped in a quadrant, the mixed phases are rapidly accelerated to rotor speed. Separation begins as the liquids are displaced upwards at continual pumping.
The separating zone extends from the diverted disk to the weir, providing a residence time for the liquid-liquid interface to form and sharpen. In most cases the CINC Solutions Centrifuge can process 100% ratio changes without further adjustment. This capability is due to a large dynamic interface zone that allows it to shift significant distance without loss of separation efficiency.
