  • the present invention relates to new additive mixtures, processes for their production and their use for turbine oils.
  • Turbines such as steam turbines, gas turbines, and water turbines, are typically used to convert kinetic energy into electricity. Effective turbine oils are essential as lubricants for trouble-free operation. The key here is the ability to provide reliable lubrication at high operating temperatures over a longer period of time.
  • a suitable general purpose turbine oil has a number of desirable properties to address various operating conditions in several types of modern industrial turbines. These properties include, for example, a high viscosity index (VI), high oxidation stability (and associated long service life), low varnish/sludge formation, good water release properties, improved rust and/or corrosion resistance and improved air release and foaming properties.
