Title: David Lawrence Cooke: Innovator in Hydroprocessing Technology

Introduction

David Lawrence Cooke is a notable inventor based in San Rafael, California. He has made significant contributions to the field of hydroprocessing technology, holding a total of 3 patents. His work focuses on improving safety and efficiency in industrial processes, particularly in the oil refining sector.

Latest Patents

One of Cooke's latest patents is a method for safely and quickly shutting down and cleaning a hydroprocessing reactor of spent catalyst via a water flooding technique. This innovative process involves shutting off hydrocarbon feed to the reactor, stripping hydrocarbons from the catalyst, cooling the reactor to a first threshold reactor temperature, purging the reactor with Ngas, introducing water into the reactor, and dumping the catalyst from the reactor. The first threshold reactor temperature is substantially greater than 200° F, and the water is introduced via a quench gas distribution system when the reactor is at a second threshold reactor temperature not greater than 200° F, cooling it to a third threshold reactor temperature not greater than 120° F.

Another significant patent by Cooke involves equipment for use in corrosive environments and methods for forming such equipment. This method is particularly relevant for structural equipment employed in sulfur-containing environments, such as oil refineries. It includes providing a steel composition with specific chemical properties and forming a structural component that meets industry standards for design, fabrication, inspection, and testing. The resulting structural equipment has a corrosion rate of less than 15 mpy, showcasing Cooke's commitment to enhancing durability and safety in challenging environments.
