Definitions

  • This invention relates generally to fuel oil compositions, and particularly relates to additives which can be utilized to correct excessive conductivity in hydrocarbon fuels.
  • the invention further relates to a method of using such compositions.
  • ULS Ultra Low Sulfur
  • Fuel electrostatics is the ability of a hydrocarbon to transport or dissipate charge accumulated in the material. Fuel electrostatics directly affects the probability of an incident (fire or explosion) due to Static Discharge Ignitions (SDI). The real risk associated with SDI is a paramount safety concern for the fuel industry.
  • Electrostatics It is widely known that electrostatic charges can be frictionally transferred between two dissimilar, nonconductive materials. When this occurs, the electrostatic charge thus created appears at the surfaces of the contacting materials. The magnitude of the generated charge is dependent upon the nature of and, more particularly, the respective conductivity of each material. The potential for electrostatic ignition and explosion is probably at its greatest during product handling, transfer, and transportation. Electrostatic charging is known to occur during solvent or fuel pumping operations. In such operations, the flow of low conductivity liquid through conduits with high surface area or through "fine” filters combined with the disintegration of a liquid column and splashing during high speed tank loading can result in static charging. Such static charging can result in electrical discharge (spark) with catastrophic potential in highly flammable environments.
  • Organic liquids such as distillate fuels (diesel, gasoline, jet fuel, turbine fuels, home heating fuels, and kerosene) and relatively contaminant free light hydrocarbon oils (organic solvents and cleaning fluids) are inherently poor conductors. Static charge accumulates in these fluids because electric charge moves very slowly through these liquids and can take a considerable time to reach a surface which is grounded. Until the charge is dissipated, a high surface-voltage potential can be achieved which can create an incendiary spark, resulting in an ignition or an explosion.
  • distillate fuels diesel, gasoline, jet fuel, turbine fuels, home heating fuels, and kerosene
  • organic solvents and cleaning fluids organic solvents and cleaning fluids
  • Hydro treating is a process by which hydrogen, under pressure, in the presence of a catalyst, reacts with sulfur compounds in the fuel to form hydrogen sulfide gas and a hydrocarbon.
  • hydro treating to reduce sulfur content results not only in the removal of sulfur from the fuel but also the removal of other polar compounds which normally increase the conductivity characteristics of the fuel.
  • a non-hydro treated fuel has conductivity in the range of 10 to about 30 pS/m 2
  • a hydro treated fuel (below 15 ppm limit) is normally below 1 pS/m 2
  • Conductivity below ⁇ 3 pS/m greatly increases the risk of catastrophic electrostatic ignition.
  • Static Dissipaters / Conductivity Improvers In order to correct the detrimental effects of hydro treating, refineries and fuel handlers are routinely utilizing Static Dissipaters / Conductivity Improvers. These additives when used properly minimize the risk of electrostatic ignition in hydrocarbon fuels and solvents. There is a great wealth of knowledge and experience regarding the use of Static Dissipaters / Conductivity Improver additives (ASTM D - 4865 Standard Guide for Generation and Dissipation of Static Electricity in Petroleum Fuel Systems, and API Recommended Practice 2003 - Protection against Ignition Arising Out Of Static, Lightening, and Spray Currents; the entire teachings of which are incorporated herein by reference). The diversity of additives which have been patented and utilized in the fuel industry exemplifies the importance of risk associated with ignition due to static discharge.
  • the present invention is directed to compositions and methods for correcting fuel oil compositions having excess conductivity.
  • the oil compositions can comprise a Petroleum Based Component, a Conductivity Additive and a Conductivity Correcting Additive.

  • Low temperature oper ability / cold flow additives are used in fuels to enable users and operators to handle the fuel at temperatures below which the fuel would normally cause operational problems.
  • Distillate fuels such as diesel fuels tend to exhibit reduced flow at low temperatures due in part to formation of waxy solids in the fuel.
  • the reduced flow of the distillate fuel affects transport and use of the distillate fuels in refinery operations and internal combustion engine. This is a particular problem during the winter months and especially in northern regions where the distillates are frequently exposed to temperatures at which solid formation begins to occur in the fuel, generally known as the cloud point (ASTM D 2500) or wax appearance point (ASTM D 3117).
  • waxy solids in the fuel will in time essentially prevent the ability of the fuel to flow, thus plugging transport lines such as refinery piping and engine fuel supply lines.

  • wax precipitation and gelation can cause the engine fuel filters to plug resulting in engine inoperability.
  • Example of Low temperature operability / cold flow marketed by Innospec Inc. of Newark, Delaware is PPD 8500.
  • Corrosion Inhibitors are a group of additives which are utilized to prevent or retard the detrimental interaction of fuel and materials present in the fuel with engine components.
  • the additives used to impart corrosion inhibition to fuels generally also function as lubricity improvers. Examples of Corrosion Inhibitors marketed by Innospec Inc. of Newark, Delaware are DCI 6A, and DCI 4A.
  • Cetane Improvers are used to improve the combustion properties of middle distillates.
  • fuel ignition in diesel engines is achieved through the heat generated by air compression, as a piston in the cylinder moves to reduce the cylinder volume during the compression stroke.
  • the air is first compressed, then the fuel is injected into the cylinder; as the fuel contacts the heated air, it vaporizes and finally begins to burn as the self-ignition temperature is reached. Additional fuel is injected during the compression stroke and the fuel burns almost instantaneously, once the initial flame has been established. Thus, a period of time elapses between the beginning of fuel injection and the appearance of a flame in the cylinder.
  • Detergents are additives which can be added to hydrocarbon fuels to prevent or reduce deposit formation, or to remove or modify formed deposits. It is commonly known that certain fuels have a propensity to form deposits which may cause fuel injectors to clog and affect fuel injector spray patterns. The alteration of fuel spray patterns may cause non uniform distribution and/or incomplete atomization of fuel resulting in poor fuel combustion. The accumulation of deposits is characterized by overall poor drivability including hard starting, stalls, rough engine idle and stumbles during acceleration. Furthermore if deposit build up is allowed to proceed unchecked, irreparable harm may result which may require replacement or non-routine maintenance. In extreme cases, irregular combustion could cause hot spots on the pistons which can resulted in total engine failure requiring a complete engine overhaul or replacement. Examples of Detergents marketed by Innospec Inc. of Newark, Delaware are DDA 350, and OMA 580.
  • Lubricity improver's increase the lubricity of the fuel, which impacts the ability of the fuel to prevent wear on contacting metal surfaces in the engine.
  • a potential detrimental result of poor lubricating ability of the fuel can be premature failure of engine components (for example, fuel injection pumps).
  • Lubricity Improvers marketed by Innospec Inc. of Newark, Delaware are OLI 9070.x, and OLI9101.X.
  • Fuel lubricity is the ability of the fuel to prevent wear on contacting metal surfaces. Certain diesel engine designs rely on fuel as a lubricant for their internal moving components. The problem of poor lubricity in these fuels is likely to be exacerbated by future engine system developments aimed at further decreasing emissions.
  • Fuel lubricity requirements can be achieved by the use of lubricity additives.
  • Dyes and Markers are materials used by the EPA (Environmental Protection Agency) and the IRS (Internal Revenue Service) to monitor and track fuels. Since 1994 the principle use for dyes in fuel is attributed to the federally mandated dying or marking of untaxed "off-road" middle distillate fuels as defined in the Code of Federal Regulations, Title 26, Part 48.4082-1(26 CFR 48.4082-1). Dyes are also used in Aviation Gasoline; Red, Blue and Yellow dyes denote octane grade in Avgas. Markers are used to identify, trace or mark petroleum products without imparting visible color to the treated product. One of the main applications for markers in fuels is in Home Heating Oil. Examples of Dyes and Markers marketed by Innospec Inc. of Newark, Delaware are Oil Red B4 and Oil Color IAR.
  • Anti-Icing Additives are mainly used in the aviation industry and in cold climates. They work by combining with any free water and lowering the freeze point of the mixture that no ice crystals are formed. Examples of Anti-Icing additives marketed by Innospec Inc. of Newark, Delaware are Dri-Tech and DEGME.
  • Demulsifiers / Anti Haze additives are mainly added to the fuel to combat cloudiness problems which maybe caused by the distribution of water in a wet fuel by dispersant used in stability packages.
  • Examples of Demulsifiers / Anti Haze additives marketed by Innospec Inc. of Newark, Delaware are DDH 10 and DDH 20.
  • Antioxidants are used to inhibit the degradation of fuels by interaction of the fuel with atmospheric oxygen. This process is known as "Oxidative Instability". The oxidation of the fuel results in the formation of alcohols, aldehydes, ketones, carboxylic acids and further reaction products of these functional groups, some of which may yield polymers. Antioxidants function mainly by interrupting free radical chain reactions thus inhibiting peroxide formation and fuel degradation. Examples of Antioxidants additives marketed by Innospec Inc. of Newark, Delaware are AO 37 and AO 29.
  • Metal Deactivators are chelating agents that form stable complexes with specific metals. Certain metals (Copper, Zinc) are very detrimental to fuel stability as they catalyze oxidation processes resulting in fuel degradation (increase in gums, polymers, color, and acidity). Examples of Metal Deactivator marketed by Innospec Inc. of Newark, Delaware is DMD.
  • Biocides are used to control microorganisms such as bacteria and fungi (yeasts, molds) which can contaminate fuels. Biological problems are generally a function of fuel system cleanliness, specifically water removal from tanks and low point in the system. Example of Biocide marketed by Innospec Inc. of Newark, Delaware is 6500.
  • Thermal Stabilizers are additives which help prevent the degradation of fuel upon exposure to elevated temperatures. Fuel during its use cycle is exposed to varying thermal stresses. These stresses are: 1) In storage - where temperatures are low to moderate, 0 to 49°C (32 to 120°F), for long periods of time, 2) In vehicle fuel systems- where temperatures are higher depending on ambient temperature and engine system, 60 to 70°C (140 to 175°F), but the fuel is subjected to these higher temperatures for shorter periods of time than in normal storage, and 3) In (or near) the engine - where temperatures reach temperatures as high as 15O 0 C (302 0 F) before injection or recycling, but for even shorter periods of time. Thermal stability additives protect the fuel uniformity / stability against these types of exposures. Examples of Thermal Stabilizers marketed by Innospec Inc. of Newark, Delaware are FOA 3 and FOA 6.
