Title: David G Thompson: Innovator in Filtration and Oil Desalting Technologies

Introduction

David G Thompson is a notable inventor based in Richmond, GB. He has made significant contributions to the fields of filtration and oil desalting, holding a total of 3 patents. His innovative work has implications for both environmental sustainability and the petroleum industry.

Latest Patents

One of Thompson's latest patents is for an "Equipment and method for filtration using a fabric of polyacrylonitrile." This invention features a backwashable filter element made primarily of polyacrylonitrile fibers, with fiber diameters ranging from 10 to 50 microns and a density between 0.05 to 0.50 g/cc. This filter element is particularly effective for filtering seawater, especially in applications where seawater is injected into petroleum reservoirs to enhance crude oil recovery.

Another significant patent is the "Method for desalting crude oil." This method reduces the salt content in crude oil by washing it with at least 1% by volume of wash water that has lower salinity than the water present in the crude oil. The process separates the mixture into a layer of crude oil with reduced salt content and a layer of saline water containing some oil. The oil-free permeate is then removed as effluent, while the oil retentate is recycled back to the washing stage, eliminating the need for additional oil recovery plants for treating desalter effluent.
