Liquid Liquid Centrifugal Separator

Liquid Liquid Centrifugal Separator

Podbielniak® Contactor

B&P’s Podbielniak® Contactor (POD®) is a horizontal axis liquid liquid centrifugal extractor that processes liquids for accelerated solvent extraction. The two main functions of this machine are liquid liquid separation (must have specific gravity difference of .01 or greater) and the liquid-liquid extraction process through counter-current flow. This separation technology is often selected for temperature-sensitive operations, when trying to reduce footprint and solvent inventory from a tower, and when speed of process is important.

The POD® has been in service for over 60 years and is still finding new applications where other liquid liquid separation or extraction processing equipment cannot perform. B&P Littleford has a very knowledgeable staff and top notch test facility to help trial the unit and identify/optimize your process.

Process Examples

Process Example 1 (solvent extraction): The separation of acetic acid from dilute solutions of water can be very costly if done by distillation alone. By running the material through the POD® first, the majority of the water is removed and the final product is realized by distilling a much smaller amount of water, which saves energy.

Process Example 2 (fermentation broth): A fermentation broth needs to be brought up to temperature for extraction but can only stand that temperature for a few minutes without degrading the active product. The POD® is the only extraction unit that will get the active product out and back down to temperature within a very short and consistent time frame.
