Turn Liquid/Gas Separation on Its Side with SepraSol™ Plus
One sizing approach, one element design, any vessel orientation.
Why Are Liquids a Problem in Natural Gas Systems
Liquid contamination continues to affect natural gas and fuel gas systems across many operating environments, particularly where vessel layout and operating conditions vary. Liquid amine carryover and free hydrocarbons can reduce separation efficiency foul compressors and contribute to unplanned maintenance. Managing these liquids becomes more complex when systems must perform reliably across fluctuation liquid and solid contamination loads.
How SepraSol Plus Works in Fuel Gas Systems
Liquid gas coalescers remove fine liquid aerosols from gas streams by capturing droplets within treated fibrous media where they coalesce into larger droplets and drain from the gas flow. Separation performance depends on media surface properties residence time and vessel configuration, particularly under variable operating conditions.
SepraSol Plus applies these coalescence principles using treated media and a validated sizing methodology to support consistent performance in both vertical and horizontal vessels.

How Does Horizontal Liquid Gas Separation Perform
The horizontal configuration extends the performance of SepraSol Plus to installations where footprint or access limits the use of vertical vessels. It uses the same validated element and a vessel layout designed to support effective liquid separation and easier maintenance.
Key updates:
- Same element design across both vessel orientations
- Easier maintenance with upstream changeout access
- Vessel length adjusted to support liquid separation
Benefits of SepraSol Plus
SepraSol Plus is designed to support reliable, long-term performance while helping facilities manage cost and operational demands. The design focuses on making maintenance easier, reducing waste and enabling a smaller footprint where needed.
Core benefits include:
- Layout flexibility to reduce footprint constraints
- Stable performance even during solids upsets and high load events
- Fine liquid removal that protects MRUs, compressors, pipelines, sieve contactors and glycol systems
How SepraSol Plus Manages High Liquid Loads
Liquid handling performance depends on both the media and the vessel design. SepraSol Plus combines Pall’s media treatment with a sizing approach that supports high liquid loading in any orientation.
This includes:
- Media treatment that lowers surface energy and speeds drainage
- Data driven selection of vessel orientation and element count
- Horizontal settling length to support coalescence and drainage
Where SepraSol Plus is Used
SepraSol Plus is used across critical natural gas processing operations where clean, dry gas is necessary to protect assets and ensure product quality.
Applications include:
- MRU protection
- Compressor protection
- Pipelines
- Sieve contactors
- Glycol systems
Results and Proof
SepraSol Plus has delivered proven performance in demanding fuel gas applications. Its ability to remove both liquids and solids helps protect critical equipment, stabilise operation and reduce maintenance requirements.
Case Study Snapshot: Refinery Fuel Gas Improvement
A refinery experiencing significant contamination in its fuel gas stream installed a SepraSol Plus coalescer skid near a malfunctioning control valve. After installation, the refinery reported stable operation, cleaner fuel gas quality and no further maintenance issues on the control valve across the operating period.
These early gains highlight how SepraSol Plus supports reliability and protects downstream equipment in demanding fuel gas applications.
Frequently Asked Questions
Can one element be used for both orientations?
Yes. SepraSol Plus is designed for vertical and horizontal vessels.
How does media treatment improve performance?
The treated media lowers surface energy which supports faster drainage.
