Claim 1

A DISTILLATE HYDROCARBON FUEL TAKEN FROM THE GROUP CONSISTING OF FUEL OILS AND JET FUELS CONTAINING (1) AS A SLUDGE INHIBITING AND DISPERSING AGENT FROM ABOUT 0.001 TO 0.1% BY WEIGHT OF AN OIL-SULUBEL, BASIC AMINO NITROGENCONTAINING ADDITION TYPE COPOLYMER CONTAINING IN COMBINED FORM AS ITS ESSENTIAL MONOMERIC COMPONENTS COPOLYMERIZABLE ETHYLENICALLY UNSATURATED COMPOUNDS EACH CONTAINING ONLY ONE POLYMERIZABLE ETHYLENIC LINKAGE, AT LEAST ONE OF WHICH COMPONENT IS AMINE-FREE AND CONTAINS FROM 8 TO ABOUT 18 CARBON ATOMS IN AN ALIPHATIC HYDROCARBON CHAIN WHICH IN THE POLYMER IS NOT PART OF THE MAIN CHAIN, AND ONE OF THE COMPONENTS AS IT EXISTS IN THE POLYMER CONTAINING A BASIC AMINO NITROGEN IN THE SIDE CHAIN, SAID COPOLYMER CONTAINING 0.1% TO 3.5% BY WEIGHT OF BASIC AMINO NITROGEN AND SAID COPOLYMER HAVING AN INHERENT VISCOSITY OF 0.1% TO 3.0 AS DETERMINED AT O.1% WEIGHT/VOLUME CONCENTRATION IN BENEZENE AT 25* C., AND, (2) A STABLIZING QUANTITY WITHIN THE RANGE OF FROM ABOUT 0.0001% TO 0905% BY WEIGHT OF SAID FUEL OF A DEMULSIFIER CONSISTING ESSENTIALLY OF AN N-(DILOWERALKYLAMINOALKYL) HYDROCARBON SULFONAMIDE PRODUCED ON A REACTION OF A CHLOROSULFONATED PETROLEUM HYDROCARBON WAX WITH A DILOWERALKYLAMINOALKYLAMINE IN WHICH THE TERITARY AND PRIMARY AMINE GROUPS ARE SEPARATED BY AT LEAST 2 CARBON ATOMS.
