14 Million Hours of Operational Experience on Phosphate ester Fluids as a Gas Turbine Main Bearing Lubricant.

Abstract

Phosphate ester fluids have been used as a gas turbine main bearing lubricant for more than 35 years. Acid treatment systems utilizing Fullers' Earth or Activated Alumina have been used to remove acids produced during the PE fluid degradation process on an intermittent or continuous basis. Both acid adsorbing medias contribute metal soaps during the acid adsorbing process. Over time, the build-up of metal soaps significantly reduces the capability of the media to adsorb acids. The end result is escalating acid levels and fluid operating problems. The introduction of ion exchange as an acid adsorbing media has eliminated the catalytic fluid degradation process, and offers phosphate ester users' extremely long fluid service life.
