Use of Hydrophobic HEPA Filters May Double Time Between Aero-engine Overhauls

Alliance Pipeline conducted a four-year evaluation of Gore HEPA filters on LM2500 aerodynamic gas turbines serving two pumping stations in Canada. The short term benefits include virtually no degradation in compressor efficiency and shaft power over the run period and a better heat rate.

The Value Proposition Offered by HEPA Filtration

The cost of an E12 HEPA filter may be as much as four or five times the price of a conventional air filter. Economic analyses conducted by owners have typically focused on compressor performance and assumed a one- to two-year lifetime for HEPAs serving high-hours engines. Based on those parameters alone the HEPA was, and continues to be, a tough sell. But where the cost of replacement power is expensive or unavailable, water washing is not feasible, or a corrosive ambient environment is causing premature engine failure, HEPA filtration may be readily justified.
