FOCUS for gas turbine protection Fuel oil cleaning unit solutions FOCUS 18 - 200 (duplex unit) Alfa Laval Fuel Oil Cleaning Unit Solutions (FOCUS) are automated modular systems for the purification of liquid fuel oils. The fuel cleaning process is designed to overcome the harmful effects of fuel oil contaminants, primarily the trace metals sodium and potassium, as well as water and solid particles. The fuel cleaning modular solution extends to suit all capacity requirements. Application High temperature corrosion, ash deposition and the clogging and erosion of fuel systems are costly operating problems attributed to fuel contaminants. Liquid fuels vary substantially in physical properties and level of contaminants, but with correct treatment a wide range of liquid fuels can be used effectively in any modern gas turbine power plant. Features and Benefits • Enable full compliance with current standards of fuel quality at the turbine inlet • Constant efficiency and highest separation efficiency of water and solids ensured • Proven, reliable operation • No pre-filtration necessary • Environmentally friendly sludge disposal (no filter cartridges) • Automatic, unattended operation • Comparatively low operating cost • Simple, compact and robust design Fig. 1 Throughput capacities for Distillate No. 2, 30°C separation temperature. Capacity reduction factors may be applied for other fuel grades. Module

Process description The FOCUS module will pump untreated fuel oil with centrifugal pumps via suction strainers to the separators. The centrifugal separator is the heart of the cleaning unit and provides a reliable and consistent method for the removal of solids and water simultaneously from fuel oils. Fig. 2 GT Separator – the heart of the cleaning unit Fig. 4 Automatic discharging centrifuge bowl Untreated fuel oil is fed continuously through the separator, where any water and solids are separated from the fuel oil by the action of centrifugal force. Separation takes place in a rotating bowl....
