1. What are the benefits of using Pall’s Liquid/Liquid Coalescers?
Pall’s liquid/liquid coalescer separators efficiently separate water, fluids, and particulate matter with lower separation, operation, and maintenance costs. These coalescers prevent catalyst deactivation in downstream processes, reduce corrosion problems in downstream equipment, eliminate the need for emulsion breaking chemicals, and help resolve many other issues.
As the liquid/liquid coalescers don’t disarm, they offer extended service life and eliminate ongoing labor costs. The filters are built with a high-performance design that leads to a smaller assembly size.
2. How do Pall’s Liquid/Liquid Coalescers work?
Pall’s liquid-liquid coalescers effectively filter using three stages.
- By removing solids with a cartridge filter, the coalescer preconditions the fluid for optimum coalescer performance.
- A high-performance coalescer medium captures the droplets that are to be separated from the bulk liquid and moves them through a coalescer media with progressively larger pores where they are coalesced to form larger droplets.
- These droplets are released from the media. The phases are separated by either coalescing filter separators or by gravity in the settling zone.
3. Why are Pall’s Liquid/Liquid Coalescers less prone to disarming in the presence of surfactants?
Pall’s specially engineered coalescing media options do not allow surfactants to coat the surface of the media fibers to prevent disarming. This is in contrast to glass fiber media that is used in most other competitor coalescer products and highly prone to disarming.
4. What are the applications of Pall’s Liquid/Liquid Coalescer systems?
Pall’s Liquid/Liquid Coalescers are used in various applications that demand efficient removal of particulate contamination and water. Some of the applications involve:
- Fuel systems and fuel delivery systems in aircraft, helicopter, ship, submarine, military, and commercial vehicles
- Refinery applications during alkylation, amine systems, and caustic treatments
- Midstream water processing
- Midstream LNG acid gas
- Separation of oil from water, ammonia, caustic, urea, and acid streams
- Molecular sieve protection, midstream molecular sieve dehydration, refinery molecular sieve dryer
