ABSTRACT:
Waxy oil distillates, preferably waxy petroleum oil distillates, most preferably waxy lube refrigerator, turbine, transformer or other speciality oil distillates which contain appreciable amounts of aromatics and polar molecule contaminants can have wax and aromatics/polars simultaneously and continuously removed from said oil using an adsorbent/desorbent system. The adsorbent system employs a combination of large pore polar adsorbent/hydrophobic molecular sieves. The desorbent system utilizes a combination small diameter polar solvent/large diameter non-polar solvent to regenerate the loaded adsorbent.
