  • Publication number: 20240327747
    Abstract: Used lubricating oils are fed to a dehydration/fuel stripping unit to create de-watered/defueled feedstock which is fed to a Vacuum Distillation Column (VDC) to remove and send lighter fractions for processing into base oil. Vacuum Tower Asphalt Extender (VTAE) is collected from the Vacuum Distillation Bottom (VDB) of the VDC and fed to a Solvent Deasphalting unit (SDA) along with a hydrocarbon solvent, to create a Concentrated Asphaltene Polymer Residue (CAPR) containing concentrations of the depleted polymer additives and wear metals. In particular embodiments, the CAPR is used to create relatively high-grade asphalt binders suitable for paving applications.
