An extraction solvent comprised of one or more ethyleneamines having structure (I), (II), or (III): where R-Rcan independently be H, C-Clinear or branched alkyl, amido (RRNC&#x2550;O), or hydroxyalkyl, where each R in the amido group independently H or Calkyl, and where x ranges from 1 to 6, may be contacted with a hydrocarbon stream to remove or extract non-acidic contaminants, such as thiophenes, benzothiophenes, alkyl sulfides, alkyl disulfides, mercaptans, aromatics, oxygenates, metals, olefins, and combinations thereof, from the hydrocarbon stream. The extraction solvent may include co-solvents and the hydrocarbon stream may be in gas and/or liquid form.

Methods and compounds for removing non-acidic contaminants from hydrocarbon streams

Saturated and unsaturated carboxylic fatty acids and alkylamine salts, alkyl esters and alkyl amide derivatives of these fatty acids are effective in improving the lubricity of hydrate inhibitor formulations, thereby effectively reducing the level of wear on moving parts of a pump under a load during pumping of the hydrate inhibitor formulation, for instance into an umbilical for a subsea hydrocarbon production operation.

Lubricity agents to increase pump efficiency in hydrate inhibitor applications

Hydrogen sulfide evolution from asphalt or heavy fuel oil may be reduced or eliminated using an additive to act as a scavenger. Zinc, in conjunction with an additional metal selected from Fe, Mn, Co, Ni, Cr, Zr, when present in the form of nano-particles of an oxide, borate or carboxylate is an effective component is preventing or mitigating the evolution of hydrogen sulfide. The nano-particles may be used neat or as a dispersion. These metals may also be complexed and used in the form of a solution. Molybdenum, when used with one or both of Fe and Zn is also a useful in any of these forms for the same purpose.

Method for reducing hydrogen sulfide evolution from asphalt and heavy fuel oils

Additives may be used to decrease the viscosity of heavy residual hydrocarbons. The additives are prepared using a formulation comprising: a first component selected from the group consisting of (alkoxylated)-(di or tri)-alkyl phenol-aldehyde (amine) resins; &#x3b1;-Olefin-maleic anhydride co-polymers and grafted polymers including half ester/amide and full ester/amide derivatives; and combinations thereof; and a second component which is a synergist and selected from the group consisting of polyamines, amidoamines, imidazolines, and combinations thereof.

Process for reducing the viscosity of heavy residual crude oil during refining

The reaction product resulting from the chemical reaction of an alkyl phenol with an acid or an anhydride selected from the group consisting of a saturated dicarboxylic acid, an unsaturated dicarboxylic acid, an anhydride of a saturated dicarboxylic acid, an anhydride of an unsaturated dicarboxylic acid, and combinations thereof, has been discovered to improve the properties of various fluids. In a non-limiting example, the reaction products may have an acid number from about 0 to about 50 that may improve the lubricity and/or corrosion of fuels and lubricants, such as hydrocarbon fuels and lubricants, when added thereto.

Fuel additives for enhanced lubricity and anti-corrosion properties

Certain branched carboxylic acids may serve as improved lubricity additive compositions in distillate fuels, and in particular for cold weather applications. Suitable branched carboxylic acids may include, but are not necessarily limited to, isostearic acid, neodecanoic acid, isononanoic acid, neononanoic acid, neoundecanoic acid, isovaleric acid, pivalic acid, and the like and mixtures thereof. The branched carboxylic acids may be used alone or together with straight chain carboxylic acids, and optionally with an aromatic solvent.
