The Benefits of Bulk Diesel Fuel Filtration in Mining

Abstract Modern surface mines are among the world's largest single consumers of diesel fuel. A typical mine site can consume in excess of 200 million liters of diesel fuel per year. Delivered diesel fuel is not necessarily clean. Depending on the mode of transportation, handling practices and local climate, incoming bulk fuel can contain up to 20 mg/L suspended solid contaminants and also significant quantities of free water.
Standard on-board fuel filters are not designed to handle high levels of contamination, and most engine manufacturers have specific fuel cleanliness requirements to ensure reliable engine operation. New developments in fuel injector technology, such as high pressure, common rail injectors will require even cleaner fuel. Therefore, particulate and water contamination in diesel fuel must be controlled throughout the entire fuel supply chain, from the bulk storage on mine sites to the injection systems on-board engines, through the use of particulate filtration and liquid coalescence technologies.
In this work, the author introduces a comprehensive approach to contamination control for the entire fuel supply chain, and discusses the benefits of using advanced filtration and separation technologies, with a particular focus on the requirements of modern high pressure, common rail fuel injection systems.
