Turbine oils are produced from a distillate lube fraction by solvent extraction to remove aromatics, e.g., with furfural, then dewaxing and hydrofinishing to saturate residual aromatics. Treatment with an organic peroxide, such as ditertiary butyl peroxide (DTBP), increases viscosity to compensate for the viscosity loss during the hydrofinishing. Dewaxing may be solvent or catalytic dewaxing or both. Peroxide treatment also reduces cloud point.
