In the oil and gas industry, compressed air reliability is crucial. From powering pneumatic valves to maintaining safety systems, uninterrupted instrument air supply ensures smooth and secure operations. One of the common challenges faced in compressor systems—particularly when using low-cost piston compressors—is ice blockages caused by oil carry-over into dryers. This issue not only disrupts operations but can also lead to costly downtime and safety risks.

At AAL, Dubai, UAE, we specialize in designing advanced Instrument Air Packages that overcome such challenges, providing reliable air compression solutions across UAE, Saudi Arabia, Qatar, Oman, Kuwait, Bahrain, and Egypt.

How Ice Blockages Form

When piston compressors are used, they often allow oil carry-over into the compressed air stream. This oil, when combined with moisture, reduces the efficiency of air dryers. In colder environments—or in sections of air dryers that reach low temperatures—moisture can freeze, leading to ice blockages inside the system.

Consequences of Ice Blockages:

• Restricted airflow in pipelines
• Malfunctioning pneumatic valves
• Risk of safety system failures
• Increased energy consumption due to system inefficiency
• Costly unplanned shutdowns

For refineries and distribution systems operated by ADNOC in the UAE, Saudi Aramco in Saudi Arabia, or QatarEnergy in Qatar, avoiding such blockages is essential to operational continuity.

Why Piston Compressors Pose a Risk

Piston compressors, while affordable, are prone to higher levels of oil carry-over. In regions like Kuwait, Oman, and Bahrain, where high humidity combines with desert heat, this accelerates water-oil contamination inside dryers, raising the risk of freezing when air passes through lower-temperature zones.

Practical Solutions to Prevent Ice Blockages

1. Use Oil-Free Compressors or Rotary Screw Units

Switching from piston compressors to rotary screw compressors significantly reduces oil carry-over, improving dryer efficiency and system reliability.

2. Install High-Efficiency Air Dryers

Desiccant or refrigerated air dryers with oil-removal filters help reduce the risk of moisture freezing within the system.

3. Implement Proper Filtration

Installing coalescing filters before dryers ensures oil aerosols are removed, protecting sensitive equipment downstream.

4. Regular Maintenance and Monitoring

Routine filter replacement, dryer inspections, and monitoring of dew point levels are essential, especially in large operations like those managed by Kuwait Oil Company (KOC), Petroleum Development Oman (PDO), and BAPCO Bahrain.

5. Correct Sizing of Instrument Air Packages

Undersized or oversized systems can worsen condensation problems. Proper sizing based on SCFM ensures optimal performance across extreme conditions in Egypt and the wider GCC.

Why Choose AAL Instrument Air Packages?
