Podbielniak® Contactor

B&P’s Podbielniak® Contactor (POD®) is a horizontal axis centrifuge that processes liquids. The two main functions of this machine are separation of liquids (must have specific gravity difference of .01 or greater) and liquid-liquid extraction 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 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 Example 1: 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: 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.

B&P Littleford is prepared and equipped to help you with your separation and extraction needs. Take advantage of our experience and technology by contacting us to see what Podbielniak technology can do for your process and bottom line.
