Abstract:
There is disclosed a method of providing at least one fuel additive to a heavy fuel oil, the method comprising: adding at least one fuel additive into a container comprising a heavy fuel oil, the addition occurring at a location removed from the end use site.
Abstract:
A method of reducing smoke and particulate emissions from steam boilers and process heaters operating on solid fuel by adding a fuel additive which contains an oil-dispersible iron compound and an over-based magnesium compound to the solid fuel.
Abstract:
A method and composition for identifying chemically tagged petroleum products can be achieved by adding one or more chemicals to a selected petroleum product wherein the chemical is immune to extraction from the petroleum product by conventional inexpensive absorbents, cannot be removed by extraction with acids, bases, or immiscible solvents, cannot be easily oxidized, reduced or reacted with common agents, is difficult to disguise by masking with other agents, has a low polarity, and has a boiling point in the range of the petroleum product the chemical is being added to. The presence of the chemical is determined by using ion mobility spectroscopy.
Abstract:
It has been discovered that compositions that are blends or mixtures of certain lubricity additives and corrosion inhibitors and/or stability additives can serve as improved lubricity additive compositions in distillate fuels. The corrosion inhibitors may include, but are not necessarily limited to, saturated or unsaturated monomer, dimer, and trimer fatty acids, succinic acids, imidazolines, and mixtures thereof. Suitable stability additives include, but are not necessarily limited to, amines, amides, amine/aldehyde condensates, polymer dispersants, and mixtures thereof, where the stability additive is different from the lubricity additive. It has been surprisingly discovered that less lubricity additive may be used in the compositions when the stability additive or corrosion inhibitor is present to achieve the same lubricity result, as compared with compositions that do not contain a stability additive or corrosion inhibitor, yet the same total amount of additive composition.
Abstract:
A method reduces combustion chamber deposit flaking and spark ignited internal combustion engines. The method includes supplying a fuel having an additive that includes a metal-containing compound to a spark ignited internal combustion engine. The metal-containing compound is supplied in an amount effective to reduce combustion chamber deposit flaking. In one example, the metal is manganese and the additive compound is MMT. The reduction or elimination of combustion chamber deposit flaking means a reduction in cold start emissions from the engine.
Abstract:
A fuel composition exhibiting improved anti-static properties, comprises a liquid fuel which contains less than 500 parts per million by weight sulfur; 0.001 to 1 ppm of a hydrecarbyl monoamine or hydrocarbyl-substituted poly(alkylenieamine); and 10 to 500 ppm of at least one fatty acid containing 8 to 24 carbon atoms, or an ester thereof.
Abstract:
The present invention is a demulsifying and corrosion-inhibiting compound formed from the salt of an amphiphilic amine and an amphiphilic acid. In a preferred embodiment of the invention, the demulsifier may be a salt of an alkyl amine and an alkyl aryl sulfonic acid. Even more preferably, the demulsifier may be a salt of a methyl, di-cocoyl amine and an alkyl aryl sulfonic acid. According to another embodiment of the invention, an organic system may be demulsified by mixing the salt of an alkyl amine and an alkyl sulfonic acid with the system to be demulsified.
Abstract:
A method of enhancing the operation of an emission after treatment system in a combustion system includes supplying a fuel and additive that includes a manganese compound to a combustion system. The fuel is then combusted in the combustion chamber to produce at least one byproduct including the manganese compound. The manganese compound is supplied in an amount effective to complex with the combustion byproduct. The combustion system may include a catalyzed, or alternatively, a continuously regenerating technology, diesel particulate filter.
Abstract:
There are disclosed fuel compositions containing an additive formed by admixture of (i) at least one ethylene polymer, (ii) the product of the condensation reaction between an aldehyde or ketone or reactive equivalent thereof and at least one compound comprising one or more aromatic moieties having at least one substituent of the formula XR1 and one further substituent R2 wherein X is oxygen of sulfur, R1 is hydrogen or a moiety bearing at least one hydrocarbyl group and R2 represents a hydrocarbyl group and (iii) at least one oil soluble polar nitrogen compound different from the condensation product and having one or more substituents of the formula NR13 where R13 represents a hydrocarbyl group containing 8 to 40 carbon atoms.
