Why Phase Separators?
Phase separators remove droplets with diameters >0.1µm from liquid/ liquid dispensions. The resulting improvement in the purity of liquid recovered from both dispersed and continuous phases increases product quality and reduces the need for downstream treatment. FRANKEN Phase separators thus increase profits significantly as the investments and operating costs are low. |
|
| |
|
|
| |
Phase Separators ('Separators') : FRANKEN designed separators guarantee a very high performance because of application of state-of-the-art design rules based on empirically verified CFD design models and use of the proprietary range of high performance internals. |
|
| |
|
|
| |
Design philosophy : Droplete- droplet coalescence on microfibre, wire mesh and profile surfaces allows large droplets ( d> 1,000 µm) to form quickly and efficiently. As these droplets flow through the phase separator vessel, density differences cause them to migrate to the liquid interface under the influence of gravity.
Since coalescence is a mechanical separation process, it cannot remove the dissolved liquids.
|
|
| |
|
|
| |
Perfect Separation :
FRANKEN phase separators are designed for optimal coalescence in separating organic or aqueous droplets.To design each separator the major parameters are
1. Droplet size distribution at the inlet
2. Wetting behavior of the two liquids
3. Interfacial tension. |
