The various aspects of fuel filtration systems that is used to replace an existing shipboard centrifugal purifier with a capacity of 8.5 L/s for marine diesel fuel (DFM) are discussed. The fuel reconditioning system (FRS) is designed for fuel filtration, and is available with a process capacities from 0.3 to 19 L/s. The spiral-wound filter design has a very high packaging ratio that allows a compact and modular design. It is found that these filtration systems are of low-cost compact systems that can process fuels and oils with high solids and high water content and reliably produce high-quality treated fuels and oils in a single pass.
