  2. Naphthenic oil - Wikipedia

    en.wikipedia.org/wiki/Naphthenic_oil

    The aniline point measure of the ability of the base oil to act as a solvent and is determined from the temperature at which equal volumes of aniline and the base stock are soluble High aniline points (approximately 100°C or greater) imply a paraffinic base stock, while low aniline points (less than 100°C) imply a naphthenic or aromatic stock.

  3. K factor (crude oil refining) - Wikipedia

    en.wikipedia.org/wiki/K_factor_(crude_oil_refining)

    The K factor or characterization factor is defined from Rankine boiling temperature °R=1.8Tb[k] and relative to water density ρ at 60°F: . K(UOP) = / The K factor is a systematic way of classifying a crude oil according to its paraffinic, naphthenic, intermediate or aromatic nature. 12.5 or higher indicate a crude oil of predominantly paraffinic constituents, while 10 or lower indicate a ...

  4. Naphtha - Wikipedia

    en.wikipedia.org/wiki/Naphtha

    Naphtha (/ ˈ n æ f θ ə /, recorded as less common or nonstandard [1] in all dictionaries: / ˈ n æ p θ ə /) is a flammable liquid hydrocarbon mixture.Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat.

  5. Petroleum naphtha - Wikipedia

    en.wikipedia.org/wiki/Petroleum_naphtha

    Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil [1] [2] [3] with CAS-no 64742-48-9. [4] It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or ...

  6. Base oil - Wikipedia

    en.wikipedia.org/wiki/Base_oil

    The most common one is a type of paraffinic crude oil, although there are also naphthenic crude oils that create products with better solubility and very good properties at low temperatures. By using hydrogenation technology, in which sulfur and aromatics are removed using hydrogen under high pressure, extremely pure base oils can be obtained ...

  7. Calumet, Inc. - Wikipedia

    en.wikipedia.org/wiki/Calumet,_Inc.

    Calumet makes numerous naphthenic and paraffinic oil products. Solvents from Calumet are used for a large number of applications, such as adhesives, water treatment facilities, paints and coatings, aluminum rolling and printing ink.

  8. Microcrystalline wax - Wikipedia

    en.wikipedia.org/wiki/Microcrystalline_wax

    Microcrystalline waxes are a type of wax produced by de-oiling petrolatum, as part of the petroleum refining process. In contrast to the more familiar paraffin wax which contains mostly unbranched alkanes, microcrystalline wax contains a higher percentage of isoparaffinic (branched) hydrocarbons and naphthenic hydrocarbons.

  9. Viscosity index - Wikipedia

    en.wikipedia.org/wiki/Viscosity_index

    The VI scale was set up by the Society of Automotive Engineers (SAE). The temperatures chosen arbitrarily for reference are 100 and 210 °F (38 and 99 °C). The scale was originally interpolated between 0 for a naphthenic Texas Gulf crude and 100 for a paraffinic Pennsylvania crude.
