Pall Coalescer System – Advanced Phase Separation Technology for Fluid and Gas Applications

Description

The Pall Coalescer System range is designed to support advanced phase separation of immiscible liquids and gas streams, helping to improve fluid cleanliness and reduce contamination-related issues in industrial processes.

These systems are used where fluids must meet strict cleanliness requirements, particularly where water, particulates, or entrained phases can negatively impact downstream equipment performance.

By improving phase separation efficiency, coalescer systems help reduce fouling, corrosion, and maintenance requirements while supporting more efficient fluid recovery and reuse processes.

Understanding Coalescer Technology

A coalescer is a separation device used to divide:

• Immiscible liquids (liquid/liquid separation)
• Liquids from gas streams (liquid/gas separation)

The separation process works by guiding fluid through multiple layers of engineered filter media with progressively changing pore structures.

As the fluid passes through these layers:

• Small dispersed droplets are captured within the media.
• Droplets merge together through contact and accumulation.
• Larger droplets form through coalescence.
• These larger droplets are then more easily separated from the continuous phase.

This controlled separation process improves efficiency compared to basic mechanical separation methods.

System Design and Selection Considerations

Coalescer system selection is based on multiple operating factors, including:

• Fluid physical properties.
• Flow rate requirements.
• Process conditions.
• Chemical compatibility with additives and process fluids.

Correct system sizing and configuration is important to ensure effective separation performance under real operating conditions.

Pall systems are engineered to be selected according to application requirements to support optimal separation efficiency.

Coalescer System Types

Pall offers a range of coalescer systems designed for different separation requirements and operating environments.

AquaSep® Plus L/L Coalescer System

The AquaSep Plus L/L Coalescer System is designed for liquid/liquid separation applications, specifically for removing water from hydrocarbon streams. This system is engineered to maintain performance even in conditions where conventional glass fibre coalescers may be affected by surfactant disarming.

PhaseSep® Coalescer System

The PhaseSep Coalescer System is designed for liquid/liquid separation in aggressive fluid conditions and applications where interfacial tension is low. It is engineered for use in demanding process environments where conventional separation media may lose efficiency due to fluid chemistry or operating conditions.

SepraSol™ Liquid/Gas Coalescer

The SepraSol Liquid Gas Coalescer is designed to remove liquids from gas streams.

It is suitable for:

• High flow rate applications.
• High liquid loading conditions.
• Gas streams requiring moisture or liquid removal.

This supports improved downstream equipment protection in gas processing systems.

Lucid™ Separator System

The Lucid Separator is designed for continuous separation of:

• Liquids from liquids.
• Solids from liquids.

It does not rely on disposable cartridges and is capable of handling:

• Difficult aqueous and hydrocarbon-based fluids.
• Up to 10% dispersed liquid phase.
• Relatively high solid concentrations.

This makes it suitable for more complex separation environments where continuous processing is required.

Operational Benefits

Coalescer systems support improved process performance by:

• Enhancing phase separation efficiency.
• Reducing equipment fouling and corrosion risks.
• Improving downstream equipment protection.
• Supporting fluid recovery and reuse.
• Reducing maintenance requirements linked to contamination.

These benefits contribute to more stable and efficient system operation in industrial environments.
