Lube oil treatment for gas turbines

Why lube oil treatment matters

In gas turbine power plants, lube oil plays a vital role in protecting rotating components and ensuring smooth, efficient performance. Over time, however, the oil becomes contaminated with fine metal particles, dust, condensate and decomposition products. These impurities settle in the lube oil sump and accelerate oil aging especially when acids react with contaminants.
Water ingress is another critical issue. If not removed, it promotes oxidation and bacterial growth, leading to premature oil degradation and increased maintenance needs. Left untreated, these issues can compromise turbine reliability and increase downtime.

GEA’s treatment solution

GEA offers a proven solution: centrifugal separation for purification and dewatering. This method is both efficient and economical, ensuring that your lube oil remains clean and your turbine protected.
Our systems are designed for continuous operation and use advanced centrifugal technology to remove contaminants without interrupting turbine performance. Whether your plant runs on low solid oils or faces challenging operating conditions, GEA’s solution ensures reliable purification and minimal downtime.

Optimizing performance

For best results, especially with higher-viscosity oils, pre-heating is recommended. GEA systems support electric, steam or hot water heating to reduce oil viscosity and enhance separation efficiency. Lower viscosity improves clarifying and separating performance, helping maintain oil quality over time.

Your benefits

With GEA’s lube oil treatment systems, you gain:

• Extended oil life and reduced replacement costs
• Lower maintenance and fewer unplanned shutdowns
• Improved turbine reliability and performance
• Compact, field-proven systems ready for seamless integration
