The Pall Phasesep® Y Series Coalescer is the latest member of the Phasesep coalescer family and is a high efficiency separation cartridge that is constructed entirely of FDA listed polyolefin material. This allows the Phasesep Y series coalescer to be used in a wide range of liquid/ liquid separations in the chemical, flavour and fragrance, and biotechnology industries where metal is not compatible and/or where FDA-listed materials are required.
The coalescer media contains a three layered tapered pore construction.
The emulsion first enters at the inside of the cartridge and passes through a coarse pre-filter layer to extend the service life.
The fluid then encounters a fine media layer that initiates the coalescing process
starting the enlargement of the droplets. The coalescing process is completed by a coarse media layer that maximizes the coalesced drop size before the fluid departs from the outside layer of the coalescer cartridge.
The presence of difficult to separate emulsions can be a costly problem in the chemical, flavor and fragrance, and biotechnology industries. Liquid contaminants can cause final products to be off-specification, deactivate expensive catalysts, foul contactor and stripping trays, lead to corrosion and delays in downstream storage tanks, and increase the costs for wastewater treatment.
Breaking stable emulsions can be a difficult task depending on the physical properties of the oil, water, and surfactant system.
Important parameters in determining the ease of separating emulsions are the interfacial tension (IFT), diffference in density, and viscosity. The IFT is a good way to assess the stability of an emulsion and is a measure of how much energy is required to create additional water /oil surface area. For very stable emulsions, the IFT can be very low and conventional glass fibre coalescers can lose their efficiency when the IFT reaches below 20 dyne/cm.
Compatibility is also a key issue when selecting a coalescer type. Pall offers a wide range of coalescers including various polymers and fluoropolymers.
