Abstract:
A chemical composition of matter comprising a wax plasticizing agent (plasticizer) tributoxyethyl phosphate, a mixture of selected long chain fatty acids (preferably C10 to C22), and a mixture of selected low-surface tension surfactants, which when added in solution to crude oil or refined products has been shown to lower both the B.S. & W. (rag layer) and the coefficient of friction of crude oils and refined products. This chemical composition of matter is particularly useful as a wax liquefaction, dispersant, and solubilization agent for asphaltene and paraffins in crude oil and refined products. The reduction in the co-efficient of friction resulting from the addition of this product to crude oil will allow crude oil to pump through pipelines with a minimum amount of resistance due to friction (drag).
Abstract:
A jet fuel additive concentrate composition comprises a solvent and a combination of components. A fuel composition and methods to improve thermal stability of a jet fuel and to reduce deposits in a jet engine include the jet fuel additive concentrate composition. The improvement in the thermal stability of a jet fuel is synergistic when the combination of components includes a cold-flow improving composition.
Abstract:
A fuel composition contains (a) a medium substantially free of to free of sulphur; (b) a detergent/dispersant additive; and (c) a liquid fuel where the medium substantially free of to free of sulphur is an aliphatic hydrocarbon solvent, and where the aliphatic hydrocarbon solvent is present from at least about 50 wt % to about 100 wt % of the total amount of the medium. The fuel composition is prepared by a process and is useful in a process, where the fuel composition includes a medium that is a hydrocarbon or a nonhydrocarbon or a mixture thereof, to increase the efficiency of an exhaust after-treatment device of an internal combustion engine.

Abstract:
A method and a betaine or amine oxide composition used therein for inhibiting, retarding, mitigating, reducing, controlling and/or delaying formation of hydrocarbon hydrates or agglomerates of hydrates. The method may be applied to prevent or reduce or mitigate plugging of conduits, pipes, transfer lines, valves, and other places or equipment where hydrocarbon hydrate solids may form under the conditions. At least one betaine or amine oxide compound is added into the process stream, where the compound may be mixed with another compound selected from amino alcohols, esters, quaternary ammonium, phosphonium or sulphonium salts, amides, simple amine salts, and combinations thereof.

Abstract:
A diesel fuel composition containing metallic additives that are stabilised against phase separation. The diesel fuel contains a colloidally dispersed or solubilised metal catalyst compound, which can be used for diesel particulate trap regeneration and, as a stabiliser, 5-1,000 ppm (weight) of an oil-soluble or oil-dispersible organic compound having a lipophilic hydrocarbyl chain having attached directly thereto at least two contiguous polar head functional groups, i.e., the functional groups are separated by no more than three carbon atoms. The diesel fuel composition is particularly suitable for use with diesel engines fitted with a particulate trap for emissions control.
