After solvent extraction, the raffinates are dewaxed to improve low-temperature fluidity. This process again produces two products: a byproduct wax that is almost completely paraffinic and dewaxed oil that contains paraffins, naphthenic and some aromatics.
This dewaxed oil becomes the base stock for many lubricants, but there is one more process that can be done to make a premium product.
