The present invention is an apparatus for simulating corrosion activity in liquid and vapor/condensate corrosion environments. The apparatus includes a container, including a lower region containing the liquid and an upper region, including a condenser, a heater for providing heat to the lower region such that the liquid is maintained at a given temperature, a vacuum pump for providing a partial vacuum at a given pressure in the upper region of the container, one corrosion probe removably positioned in the liquid, and a second corrosion probe removably positioned above the liquid.

Process for assessing inhibition of petroleum corrosion

A fuel system for on-board vehicle fuel separation to supply engine fuel compositions formulated as a function of driving cycle conditions. The invention results in improvements in one or more of feed efficiency and combustion emissions.

Fuel composition supply means for spark ignition engines

The invention is a process for decreasing the acidity of an organic acid containing petroleum oil, comprising contacting said petroleum oil containing organic acids with an effective amount of an alcohol and an effective trace amount of a base selected from Group IA and IIA metal carbonates, hydroxides, phosphates, biphosphates and mixtures of a hydroxide and phosphate and/or biphosphates at a temperature and under conditions sufficient to form the corresponding ester of said alcohol.

Process for treatment of petroleum acids

The present invention relates to a method for inhibiting high temperature of corrosion-prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of phosphorous acid, typically up to 1000 wppm, to the metal surface.

Method for inhibiting corrosion using phosphorous acid

The invention relates to processes for treating acidic crudes or fractions thereof to reduce or eliminate their acidity and corrosivity by addition of suitable amounts of Group IA or Group IIA oxides, hydroxides and hydrates and Group IIA metal naphthenate salts. The process has the additional benefits of reducing materials handling problems associated with treating acidic crude oils using liquid solvents and in reducing emulsion formation.

Process for decreasing the acid content and corrosivity of crudes

Fuel composition supply means for driving cycle conditions in spark ignition engines

The present invention relates to a method for inhibiting corrosion of corrosion-prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of certain sulfur and phosphorus-free aromatic compounds substituted with nitrogen, containing functional groups at the 5- or 3, 5-position, typically up to 1000 wppm, to the metal surface.

Method for inhibiting corrosion using certain phosphorus and sulfur-free compounds

The present invention relates to a method for inhibiting high temperature corrosion of corrosion prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of 4-sulfophthalic acid, typically up to 1000 wppm, to the metal surface.

Method for inhibiting corrosion using 4-sulfophthalic acid

The present invention relates to a method for inhibiting high temperature corrosion of corrosion prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of an additive aromatic compound tri-substituted with acidic functionalities selected from 5-hydroxyisophthalic acid and 1,3,5-benzenetricarboxylic acid, typically up to 1000 wppm, to the metal surface.

Method for inhibiting corrosion using certain aromatic acidic species

The present invention relates to a method for inhibiting high temperature corrosion of corrosion prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of triphenylstibine, typically up to 1000 wppm, to the metal surface.

Method for inhibiting corrosion using triphenylstibine

The invention relates to processes for treating acidic crudes or fractions thereof to reduce or eliminate their acidity by addition of effective amounts of crosslinked polymeric amines having a pKa of greater than 9 such as polyvinyl amine and anionic exchange resins having amino groups. The process has utility for crude processing.

Process for extraction of naphthenic acids from crudes

The present invention is a process for decreasing the acidity of a starting acidic crude oil by contacting an acidic crude with an effective excess of ammonia dissolved in said crude to form an ammonia-continuous oil discontinuous phase at a temperature and conditions sufficient to form the corresponding amide of the naphthenic acids. The process is useful in the processing of acidic crudes.

Process for treatment of petroleum acids with ammonia

The present invention relates to a process for reducing the acidity of a petroleum oil containing organic acids comprising treating said petroleum oil containing organic acids with an effective amount of an alcohol at a temperature and under conditions sufficient to form the corresponding ester of said alcohol.

Esterification of acidic crudes

In one embodiment, the invention is related to a process for desalting crude oil that requires less wash water than conventional desalting methods. In the preferred embodiment of the invention, a chemical demulsifier formulation comprising an emulsion-breaking chemical and a solvent carrier is added to the crude oil. Wash water is then added to the crude oil until the volume of water in the oil ranges from about 0.1 to about 3 vol. %. Subsequently, the mixture of crude oil, wash water, and chemical demulsifier formulation is subjected to opposed-flow mixing. Chemical emulsion-breakers useful in the invention have a hydrophobic tail group and a hydrophilic head group. Preferably, the emulsion breaker has the formula:

Crude oil desalting method

The invention is a process for decreasing the acidity of an organic acid containing petroleum oil, comprising contacting said petroleum oil containing organic acids with an effective amount of an alcohol and an effective trace amount of a base selected from Group IA and IIA metal carbonates, hydroxides, phosphates, and mixtures of a hydroxide and phosphate at a temperature and under conditions sufficient to form the corresponding ester of said alcohol.
