Turbine oil production
This paper describes a method of making a turbine oil from a distillate lubricant fraction by aromatics extraction of the distillate fraction to produce a raffinate with a reduced aromatic content, catalytic hydrodewaxing of the raffinate to produce a dewaxed raffinate having a pour point below 20{degrees}F and a cloud point more than 10{degrees}F above the pour point hydrotreating the dewaxed raffinate to hydrogenate aromatics in the dewaxed raffinate to produce an intermediate product having an aromatic content below 5 wt % and a reduced viscosity relative to the staring material and an unacceptably high cloud point, characterized by treating the dewaxed raffinate with an organic peroxide compound to increase the viscosity of the dewaxed raffinate and to reduce the cloud point to within 10{degrees} F of the pour point.
