Electrostatic coalescence means
Abstract
Abstract THIS INVENTION RELATES TO HYDROCARBON FUEL FILTRATION AND, MORE PARTICULARLY, TO ELECTROSTATIC COALESCENCE ASSISTED FILTRATION OF SOLID AND LIQUID CONTAMINANTS FROM REFINED HYDROCARBON FUELS AND NON-WATER-SOLUBLE HYDROCARBONS SUCH AS THOSE CONTAINING SURFACE ACTIVE ADDITIVES. THE CONTAMINANTS ARE REMOVED BY INCLUDING A FIRST CHARGED EMITTING SCREEN ELECTRODE IN THE FLUID FLOW WITH A CONDUCTIVE FIBROUS COLLECTING BED DOWNSTREAM THEREFROM. THE METALLIC COATED FIBERS FUNCTION SUBSTANTIALLY AS A COLLECTING ELECTRODE IN THE FORM OF CAPILLARIES TO ATTRACT VERY SMALL PARTICLES OF CONTAMINANTS AND CAUSE THEM TO COLLIDE WITH OTHERS TO PRODUCE LARGER UNITS, SUCH AS DROPS, THUS INCREASING COALESCENCE. THE HEAVIER, COALESCED DROPS OF WATER CONTAMINANTS ARE DRAINED OFF LEAVING THE FUEL SUBSTANTIALLY FREE OF THIS CONTAMINANT. SOLID CONTAMINANTS ARE TRAPPED AND RETAINED IN A FIBROUS FILTER BED IMMEDIATELY UPSTREAM FROM THE CONDUCTIVE FIBER COALESCING BED.
