Retrofits Facet* Tie-Rod Mount Style ElementsPall’s PhaseSep® FR1 Series liquid / liquid coalescer is designed to directly retrofit Facet International coalescer vessels designed to hold tie-rod mount style liquid / liquid coalescers.
The Pall PhaseSep FR1 system is a multiple stage unit starting with preconditioning of the fluid with a Pall particulate filter followed by the PhaseSep FR1 coalescer. The preconditioning filter removes particulate matter to prolong the service life of the PhaseSep FR1 coalescer and initiates coalescence of the dispersed phase.
Pall preconditioning particulate filters are available in numerous configurations that can fit directly into your current prefilter housing. If you do not have a prefilter installed,a system can be provided by Pall.
The PhaseSep FR1 Series coalescer vessel utilizes the same proprietary PhaseSep medium that Pall employs when it sells new liquid / liquid coalescer systems. The FR1 series product allows customers to adopt Pall coalescer technology without the need to purchase new capital equipment.
|Specially formulated fluoropolymer medium||Wide chemical and temperature compatibility||Better to withstand upsets in pH and temperature|
|Can separate liquids that have low interfacial tension||Eliminates need for emulsion breaking chemicals|
|Coalescence performance not impaired by the presence of surfactants or corrosion inhibitors||Excellent fluid quality
Continuous protection of downstream equipment
|High void volume medium in prefilters and PhaseSep® FR1 coalescers||Long service life||Lower separation costs|
|Product directly retrofits current facet tie-rod style housings holding CA, CB and CC style elementsProduct directly retrofits current facet tie-rod style housings holding CA, CB and CC style elements||No need to purchase new capital equipment||Improved liquid/liquid separations with no capital expenditures|

- Separation of pyrolysis gas from quench water in ethylene plants
- Separation of oil from water
- Remove dispersed liquid contamination to a level consistently less than 20 ppmw oil and grease*
- Handle dispersions with inlet liquid contaminant concentrations as high as 10%
- Separate dispersions with interfacial tensions as low as 0.5 dyne/cm
* By Infrared Method (EPA413.2)
Pall Corporation must review each application for the PhaseSep FR1 Liquid/Liquid Coalescer for technical feasibility. It must be determined if enough coalescer area is possible and if the existing Facet housing is long enough to prevent the two liquid phases from recombining once the emulsion is broken.
If appropriate, two or more 20 inch long Pall PhaseSep FR1 style coalescers can be coupled together with a Pall supplied coupler to increase the amount of coalescer area in the housing.
Figure 2: Filtration: Solid particles are removed from the fluid stream by the filter medium.
Coalescence: Small droplets are merged into larger ones as they pass through several layers of filter media in the coalescer.
Separation: Gravity takes effect, the large droplets are separated from the product fluid stream.

CompatibilityTo determine if the PhaseSep FR1 coalescing element is compatible with your process fluid,please contact your Pall distributor or Pall applications engineer.
Operating CharacteristicsMaximum Temperature*: 300°F / 149°C Initial Pressure Drop: 2 psid / 137 m bar d Recommended Maximum Pressure Drop: 15 psid / 1 bar d
* With chemically compatible fluids.
Once the application has been approved as suitable and the vessel size is determined to be large enough by a Pall scientist:
- The current prefilter elements and the current Facet coalescers are removed from service
- If required,the existing coalescer tie-rods are removed using the Pall wrench provided and Pall tie-rods installed
- Pall prefilters are installed in current housing or in new Pall prefilter vessel
- Pall PhaseSep® FR1 Coalescers installed
The PhaseSep FR1 coalescer can break emulsions by removing a dispersed, non-dissolved liquid phase from a bulk liquid. It cannot remove dissolved liquids from another liquid.
