What if we told you that 98% air and 2% fuel is the input of your most valuable assets, your turbines? Now what if we told you that 100% of that air contains pollutants that can damage your turbines if they’re not properly filtered?
The air in every production site is different due to weather patterns, the dust concentration level, temperature, pollutant sources, etc. Filtration systems should therefore be optimized to local site conditions, however, most systems are standardized, or in other words, optimized for CAPEX reduction over OPEX optimization*.
Consider the impact of filtration in terms of power output, availability, and ultimately, total value added to your operation when it is adapted to your location conditions and operational regime:
In our industry, it’s important to make smart purchases that will last long and have a positive impact to your bottom line. The following table shows examples of companies that yielded a return on investment in less than 2 months by investing in filtration tailored specifically for their site (identities undisclosed due to privacy).
| Case 1 | Case 2 | |
|---|---|---|
| Engine | 4 GE Frame 9 FA engines of 255 MW per unit | 10 GE LM 6000 engines of 42 MW per unit |
| Environment | Rural: seasonal agriculture, insects, birds, pollen, leaves, mist | Industrial: hydrocarbons, nearby industrial process debris, salt, cement dust, pollen |
| Problem |
Decrease in compressor efficiency over time due to degradation (fouling) |
Decrease in compressor efficiency over time due to degradation (fouling) |
| Solution |
Filter class upgrade from a two stage (G4, F8) to a three stage (G4, F8, E10) |
Filter class upgrade from a two stage (G4, F9) to a two stage (F8, E10) Total cost: $270,000 USD for 10 engines |
| Total savings |
$6.8M USD/year total for 4 engines |
$1.9M USD/year total for 10 engines |
In short, upgrading to the right filtration for your site is not only cheap insurance to make sure your engine doesn't corrode, but it's also a big benefit to your bottom line.If you believe your site is vulnerable to seasonal outage and think that there is a savings opportunity for your site, contact us to receive a free life cycle cost analysis.
