How Can You Improve Compressor Reliability?
Challenge
Fine liquid aerosols and solid particles can bypass conventional separators, contributing to compressor fouling, increased energy consumption, shorter maintenance intervals and unplanned shutdowns.
Solution
Combining bulk separation with high-efficiency filtration can help capture liquid slugs, fine aerosols and particulates before they reach compressors and downstream equipment.
Contamination is a common cause of compressor fouling, wear and unplanned downtime across gas processing, refining and transmission operations. While conventional separation technologies help remove larger contaminants, fine solids and liquid aerosols can remain in the gas stream and reach critical compressor components.
Pall helps operators reduce contamination risks through high-efficiency gas filtration and liquid/gas coalescing solutions designed to protect compressors and downstream equipment.
HFG High-Flow Gas Filters
Help remove abrasive particulate contamination from gas streams before it reaches critical equipment. Suitable for applications where solid contamination is a primary concern.
SepraSol™ Plus Liquid/Gas Coalescers
Designed to remove fine liquid aerosols and particulate contamination that conventional separation equipment may not effectively capture. Suitable for both inlet and discharge compressor protection applications.
Why Does Contamination Affect Compressor Performance?
Many compressor systems already use knock-out drums, mesh pads, vane separators or centrifugal separators. While these technologies help remove larger contaminants, fine solids and liquid aerosols can remain in the gas stream. Field measurements conducted across gas processing, refining and transmission applications found significant contamination downstream of conventional separation equipment.
Over time, these contaminants can accumulate within compressor systems, contributing to fouling, wear, reduced efficiency and increased maintenance requirements.
What Types of Contamination Should Be Controlled?
Gas streams typically contain both solid particulates and liquid aerosols. Common contaminants include corrosion products, salts, catalyst fines, hydrocarbon aerosols, lubricating oil mist and process water carryover.
Because both solids and liquids can contribute to compressor damage, many applications require a combination of filtration and coalescing technologies.
How Does Contamination Impact Compressors?
Contamination affects reciprocating and centrifugal compressors in different ways, but both can experience reduced reliability and increased maintenance requirements when contaminants reach critical components.
| Compressor Type | Typical Impact |
|---|---|
| Reciprocating Compressors | Valve fouling, piston ring wear, cylinder damage and pressure packing deterioration. |
| Centrifugal Compressors | Blade fouling, salt deposition, rotor imbalance, diffusor fouling and seal wear. |
Removing contaminants before they reach compressor internals can help support reliability, efficiency and longer maintenance intervals.
What Results Have Operators Achieved?
Across gas processing, transmission and refining operations, operators have implemented high-performance filtration and coalescing technologies to address contamination-related reliability challenges.
Where Should Compressor Filtration Be Installed?
Effective compressor protection often requires a multi-stage contamination control strategy.
Upstream filtration helps remove contaminants before they reach critical compressor components. Depending on the application, this may include bulk liquid separation followed by high-efficiency filtration or coalescing technologies for fine contaminant removal.
Downstream filtration can help protect amine systems, glycol contactors, molecular sieves, turbines and catalyst beds from contamination originating upstream or from the compressor itself.
Why Choose High-Performance Compressor Filtration?
Effective contamination control can help support:
- Reduced risk of unplanned shutdowns
- Longer maintenance intervals
- Reduced maintenance requirements
- Extended filtration element life
- Protection of downstream equipment
- Improved compressor reliability
These benefits were demonstrated across the field studies and operating applications described in the source document.
