CONTINUOUS PLURAL STAGE HEATED VAPOR INJECTION PROCESS FOR RECOVERING LUBE OIL BASE STOCKS FROM USED MOTOR OIL FORMULATIONS, AND ASPHALT BLEND COMPOSITIONS CONTAINING USED MOTOR OIL BOTTOMS FROM SAID PROCESS

This invention relates to a process for recovering lube oil base stocks from used motor oil formulations. In particular, this invention relates to the removal of metallic additive packages from the waste oil to facilitate further processing of the used motor oil. The invention further relates to asphalt blend compositions containing used motor oil bottoms from the process, and asphalt pavement compositions containing the asphalt blend compositions. A continuous, hot vapor injection process and apparatus is provided for recovering lube oil base stocks from used lubricating oil containing distillable liquid hydrocarbons and water. Also disclosed is an asphalt blend composition containing an asphalt component and the bottoms from the above process.
