Abstract: A process for heavy base oil production, comprising: a. performing an aromatic extraction of a first hydrocarbon feed to produce an aromatic extract, and a waxy raffinate; b. mixing the aromatic extract with a second hydrocarbon feed to make a mixed feed having greater than 2,000 wt ppm sulfur; c. feeding the mixed feed to a hydroprocessing unit to produce a heavy API Group II base oil having a kinematic viscosity at 70° C. from 22.6 to 100 mm2/s. An integrated refinery process unit for making heavy base oils, comprising: a. an aromatic extraction unit fluidly connected to a solvent dewaxing unit and a hydroprocessing unit; b. a first line from the aromatic extraction unit, that feeds an aromatic extract to a second hydrocarbon feed to make a mixed feed having greater than 2,000 wt ppm sulfur; and c. a connection that feeds the mixed feed to the hydroprocessing unit.
