Definitions

  • the present invention relates to additives for systems of hydrocarbon fuels containing water. More particularly, the present invention relates to biocidal treatments for water-hydrocarbon based fuel emulsions and hydrocarbon based fuels, such as diesel or biodiesel systems containing water.
  • the treatment comprises at least one biocidal alkyl ethanolamine agent or a combination of a biocidal agent and at least one alkyl ethanolamine.
  • hydrocarbon based fuels such as diesel fuels, gasoline and kerosene
  • performance enhancing additives such as water (emulsified fuel), emulsifiers, biocides, pH modifiers, detergents, etc.
  • water emulsified fuel
  • emulsifiers emulsifiers
  • biocides emulsifiers
  • pH modifiers emulsifiers
  • detergents emulsifiers
  • Two areas of current commercial interest are the formulation of emulsified diesel fuel and the use of plant derived diesel fuel alternatives known as biodiesel. In diesel engines, the high temperatures reached during combustion may increase the tendency for the production of nitrogen oxides (NO x ) and sulfur oxides (SO x ).
  • NO x nitrogen oxides
  • SO x sulfur oxides
  • Nitrogen oxides are formed via the reaction of atmospheric nitrogen and oxygen in the combustion chamber and, to a far lesser extent, from oxidation of organic nitrogen species in the fuel.
  • the rates at which various NO x type species form are related to combustion temperature, and it has been found that a small reduction in flame temperature can result in a large reduction in the production of nitrogen oxides.
  • One approach to lowering flame temperature is to inject water into the combustion chamber. This method allows for existing fuels to be used as is, but it requires costly and complicated changes in engine design.
  • water-hydrocarbon based fuel emulsions One problem that exists in such water-hydrocarbon based fuel emulsions is the growth of microorganisms that utilize the mostly hydrocarbon based fuel as a nutrient. Such microorganisms or microbes will tend to grow in the water phase, but they can also become dispersed in the hydrocarbon fuel phase leading to degradation of the hydrocarbon fuel.
  • biodiesel In the case of biodiesel, microorganisms can grow in the pure fuel with just the traces of water naturally present as a contaminant (typical water specification for biodiesel is 50 ppm). All such contamination or degradation can cause sludge formation that clogs fuel filters and other engine components.
  • US patent number 3,883,345 disclosed the use of a bactericidal agent such as an alkyl pyridinium or picolinium halide to inhibit microorganism related sludge in fuel oils.
  • UK patent number 1 ,325,913 discloses the use of a condensation product of an aliphatic aldehyde such as formaldehyde and a primary or secondary alkanolamine such as diethanolamine to control microorganisms in hydrocarbon fuels.
  • US patent number 6,607,566 discloses a method for producing a highly stable aqueous fuel emulsion.
  • the fuel emulsion can include corrosion inhibitors including alkanolamines for pH control as well as biocides.
  • US Patent Application Publication number US 2003/0162845 A1 discloses the use of de-activatable biocides in hydrocarbonaceous products.

  • a biocide and at least one alkyl ethanolamine to a water-hydrocarbon based fuel system to inhibit microbiological activity.
  • contact with water either intentionally or through contamination can result in undesirable biological activity.
  • the microbiological activity can result in degradation of the fuel, sludge formation, undesirable odor generation, etc.
  • the use of biocidal agents in such systems is known.
  • the present inventors have discovered that the addition of a combination of a biocidal agent and at least one alkyl ethanolamine to such systems results in unexpected increased biocidal activity.
  • the combination of the present invention can allow a reduction in the amount of biocide necessary to achieve a given level of control.
  • the alkyl ethanolamine in addition to enhancing the activity of the biocide, also can provide pH control for the system. Such pH control can reduce possible corrosion problems.
  • the favorable impact of the amine is particularly important in the plant-derived fuels known generically as biodiesel.
  • the biocidal agent-alkyl ethanolamine treatment of the present invention can be employed in combination with conventional additives for hydrocarbon fuel systems containing water such as water-hydrocarbon emulsion systems and/or non-emulsion fuels containing or contaminated with small amounts of water.
  • Conventional additives can include emulsifiers, detergents, pH adjusting agents, etc.
  • the treatment of the present invention can be employed in systems containing hydrocarbon based fuels such as diesel fuel, gasoline, kerosene, heating oils, etc.
  • biocide or biocidal agent refers to any substance that kills or inhibits the growth of microorganisms such as bacteria, molds, slimes, fungi and the like.
  • the water or aqueous phase can comprise between 0.01% and 25% by weight of the system.
  • Such water contamination can result from condensation in large storage or transportation vessels.
  • such contamination can result from non-exclusive use of storage tanks.

  • the use of the combination of the present invention allows for a decrease in the amount of biocide needed to provide a desired level of control, or an increase in the level of biocidal control without an increase in the amount of biocide employed.
  • the alkyl ethanolamines of the present invention are of the formula: R X NHZ(CH 2 CH 2 OH)Y wherein R is C 3 to Cis alkyl or isoalkyl group, X and Y are 1 or 2, Z is 0 or 1, X+Y is not greater than 3, when X or Y is 2 than Z is 0 and when X is 2 the R groups are the same or different C 3 to Cis alkyl or isoalkyl groups.
  • Preferred alkyl ethanolamines include butyl diethanolamine, Butylaminoethanol, dibutylaminoethanol and diisopropylaminoethanol.
  • the alkylamine ethoxylate can be added to water-hydrocarbon based fuel systems at treatment concentrations from about 100 to 8000 parts per million (ppm) and preferably at treatment concentrations of from about 1000 to 5000 ppm.

  • biocides may comprise benzoisothiazolone such as Proxel DB20, a 20% suspension of benzoisothiazolone available from Avecia, and the like.
  • the biocide can be added in concentrations from about 100 to over 2000 ppm. However, to minimize potential adverse environmental impact, it is preferred to use lower levels of biocide. In the combination of the present invention, biocide concentrations of from about 100 ppm to about 1500 ppm have been found to be effective. In cases wherein the biological challenge is minimal, the alkyl ethanolamines of the present invention may be used as the sole biological control agent.
