How does turbine oil for steam turbines differ from that used in gas turbines?

Differences include:

Operating Temperatures: Steam turbines typically operate at lower temperatures than gas turbines, affecting oil formulation.
Water Exposure: Steam turbines are more prone to water contamination, requiring excellent demulsibility.
Viscosity Requirements: May differ due to variations in design and operating conditions.
Additive Packages: Steam turbine oils may focus more on rust and corrosion inhibitors, while gas turbine oils emphasize oxidation stability.
Selecting the appropriate oil ensures optimal protection and performance for each turbine type.
