20150027925 | LUBRICANT BASE OIL HYDROPROCESSING AND BLENDING - Methods are provided for producing a plurality of lubricant base oil products with an increased overall yield.

The fractionation cut points are selected to so that the feed fraction for forming a light lubricant base oil has a higher Noack volatility and a lower viscosity than the desired targets for the lighter lubricant base oil. The feed fractions are then hydroprocessed separately to achieve desired properties. After hydroprocessing, a portion of the heavier base oil is blended into the light lubricant base oil to produce a blended base oil product. This returns the volatility and the viscosity of the blended base oil to the desired specifications. | 01-29-2015 |
