Title: The Innovations of Leonard R. Watts
Introduction
Leonard R. Watts is a notable inventor based in Nederland, Texas. He has made significant contributions to the field of petroleum processing, particularly in the area of dewaxing processes. With a total of 2 patents, his work has had a lasting impact on the industry.
Latest Patents
Watts' latest patents focus on innovative solvent dewaxing processes. The first patent describes a method wherein an intermediate range waxy distillate oil is heated to dissolve all wax. This oil is then mixed with a dewaxing solvent at a temperature between 60°F and 80°F, forming an oil-solvent mixture that is cooled to a temperature below the depressed cloud point. This process allows for the effective precipitation of wax, resulting in a first wax/oil/solvent mixture. Additional solvent is then mixed with this mixture to precipitate more wax, leading to a second wax/oil/solvent mixture from which the wax is separated.
The second patent outlines a similar dewaxing process for waxy petroleum distillate oil stock. In this method, one volume of waxy oil stock is combined with 0.5-2 volumes of aromatic hydrocarbon dewaxing solvent. The mixture is heated to dissolve all solid wax, then cooled to a selected separation temperature to precipitate wax crystals. This mixture is further treated with ketone dewaxing solvent to recover solid wax and dewaxed oil as final products.
