The inability to efficiently separate Liquid/Liquid emulsions can be a very costly problem in the oil, gas, and chemical industries. Liquid contamination can cause final products to be off-specification, rapid deactivation of downstream catalysts, corrosion of downstream storage facilities, and increased costs for wastewater treatment. Breaking stable emulsions can be difficult depending on the physical properties of the oil, water, and surfactant system.
Pall’s Liquid/Liquid Coalescers offer effective Liquid/Liquid separations. Emulsions are broken into two phases are broken into two phases using a highly efficient Liquid/Liquid separation method that utilizes a polymeric material that can handle very low interfacial tension (IFT) and does not disarm with surfactants. The prefilter provides particulate control for long coalescer life and optimizes operating costs.
The Liquid/Liquid Coalescers provide free water removal to a level as low as 15 ppmv and are available in horizontal and vertical orientations to suit budgetary, size, weight, and footprint needs. While the vertical configuration provides a smaller capital footprint, the horizontal configuration offers easier change-out, higher flow, and lower vessel costs.
Why choose Liquid/Liquid Coalescers?
Pall’s Liquid/Liquid Coalescers provide several benefits, including:
- Improved fluid quality, consistency, and value
- Lower operating, disposal, and maintenance costs
- Lower separation costs
- Prevention of catalyst deactivation in downstream processes
- Reduced corrosion problems in downstream equipment
- Prevention of disarming, thereby increasing service life
- Eliminating the need for emulsion breaking chemicals
- Extended time between scheduled maintenance periods
- Elimination of ongoing labor costs to change disarmed glass fiber coalescer elements or mesh packs
- Efficient, high-performance design for smaller assembly size
