Title: The Innovations of David E Graham
Introduction
David E Graham, an innovative inventor based in Fleet, GB, has made significant contributions to the field of filtration and crude oil processing. With a portfolio of four patents, his work primarily focuses on methods that enhance the efficiency and effectiveness of filtering systems and crude oil desalting techniques.
Latest Patents
Among his notable inventions is the patent for "Equipment and method for filtration using a fabric of polyacrylonitrile." This innovation consists of a backwashable filter element made from polyacrylonitrile fibers, specifically designed to filter seawater, particularly in applications related to petroleum extraction. The design accommodates fiber diameters ranging from 10 to 50 microns and a density between 0.05 to 0.50 g/cc.
Another significant patent by Graham is the "Method for desalting crude oil." This process reduces the salt content in crude oil by utilizing wash water of lower salinity, promoting the separation of crude oil and saline water. By applying a higher volume of wash water—greater than 7.5% by volume of the crude oil—Graham's method leads to the formation of less stable emulsions, which can be broken more easily to recover desalted crude oil.
Career Highlights
David E Graham has worked with distinguished organizations, notably the British Petroleum Company, P.L.C., and Intevep, S.A. His experiences in these companies have shaped his approach to developing innovative solutions for the oil and gas industry, enhancing the methodologies for handling crude oil and water separation.
Collaborations
Throughout his career, Graham has collaborated with esteemed coworkers such as David G Thompson and Werner A Lidy. These partnerships have contributed to advancing the technologies available in the filtration and oil processing sectors.
Conclusion
David E Graham's contributions to innovation in filtration and crude oil processing highlight the essential role of inventors in addressing industry challenges. His patented methods not only advance technological capabilities but also pave the way for more efficient practices in oil recovery and environmental sustainability.
