Introduction

Arthur G Shaffer, Jr. is an accomplished inventor based in Grayson, KY (US). He has made significant contributions to the field of recycling used motor oil through his innovative processes. With a total of 2 patents, his work focuses on improving the efficiency and effectiveness of oil re-refining techniques.

Latest Patents

Shaffer's latest patents include a process for the direct contact heating and vaporization of used motor oil (UMO). This process, titled “Pumped” recycle vapor, utilizes a superheated, condensable vapor to heat and vaporize distillable liquid hydrocarbons from a waste motor oil stream. The result is an overhead vapor fraction that combines injected superheated vapor with vaporized boiling range components. This material is then cooled and partially condensed to yield lube boiling range liquid hydrocarbons and a vapor phase, which is condensed to create a recycle liquid phase.

Another notable patent involves the vaporization of used motor oil with non-hydrogenating recycle vapor. In this process, used motor oil is re-refined by the direct injection of a superheated, non-hydrogenating recycle vapor. Operating at low pressures, preferably from atmospheric to 10 atmospheres absolute, this method significantly reduces fouling that can occur with indirect heat exchange methods.
