Abstract:
Provided in one embodiment is an improved and more flexible process for preparing a finished base oil or a white oil product comprising passing a dewaxed base oil product to a distillation column and separating the dewaxed base oil product into fuel and base oil product streams. The base oil product streams are tested to determine if they meet desired specifications. Base oil product streams that meet the desired minimum base oil specifications are passed to a hydrofinishing reactor to prepare a white oil product, or passed to direct sale.
