Title: Innovations by Charles W. Harrison in Lubricating Oil Reclamation

Introduction

Charles W. Harrison, an accomplished inventor from Nederland, TX, holds an impressive 21 patents, primarily focusing on advancements in the field of lubricating oil reclamation. His contributions have greatly impacted the efficiency of oil reuse and environmental sustainability.

Latest Patents

Among his latest patents, two significant inventions stand out. The first is a process for reconstituting used lubricating oil that includes lube oil additives such as zinc dithiophosphate. In this process, zinc dithiophosphate is thermally decomposed within a temperature range of 400°F (204°C) to 1000°F (538°C) over a residence time of 10 to 120 minutes. The oil produced is then subjected to vacuum distillation, resulting in a zinc-free oil suitable for use as a lubricating oil blending stock. Notably, approximately 5 to 25 vol % is recovered in the form of a metal-containing bottoms product, which can be utilized as an asphalt extender.

Harrison's second notable patent is focused on the reclaiming of used lubricating oil. Similar to his first invention, this process also involves thermally decomposing zinc dithiophosphate under the specified temperature conditions and time. The resultant distillate oil, once subjected to vacuum distillation, is recognized as being useful as marine diesel fuel. Again, a portion of the product is recovered as a metal-containing bottoms product for asphalt extension, completing a cycle of innovation in oil recovery.

Career Highlights

Throughout his career, Charles W. Harrison has made valuable contributions while working with renowned companies such as Texaco Inc. and Star Enterprise.
