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.
The white gas sold today is a similar product but is produced at refineries and has a very low benzene content, benzene being a human carcinogen. [ 5 ] Though Coleman fuel has an octane rating of 50 to 55 and a flammability similar to gasoline, it has none of the additives found in modern gasoline .
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 ...
For refineries, the interest has been primarily focused on the distribution between the distillation fractions: petrol, paraffin, gas oil, lubricant distillate, etc. Refiners look at the density of the crude oil – whether it is light, medium or heavy – or the sulfur content, i.e. whether the crude oil is “sweet” or “sour”.
Fisher Scientific offers a product 'Benzine (Petroleum Naphtha)' that retails for a high price that would suggest it is a specialty product but conforms to Marathon Petroleum's 'VM&P Naphtha' (Varnish Makers & Painters’ Naphtha) found widely distributed in many hardware stores in North America. [2]
The most common diluent used to dilute bitumen is natural gas condensate (NGC), especially the naphtha component. [5] Due to insufficient quantity of natural gas condensate in Alberta, bitumen shippers also use refined naptha and synthetic crude oil (SCO) as diluent, and import a considerable amount from the U.S. [6] Although SCO requires a higher volume percentage to achieve the same ...
The discussion above about the differences between the various fuels - white gas, unleaded gas, octane, naphtha and Coleman fuel - is sort of right, but also a little off the mark. It can get a little confusing because some of the terms have different usages over time and/or in different contexts.
Steam cracker units are facilities in which a feedstock such as naphtha, liquefied petroleum gas (LPG), ethane, propane or butane is thermally cracked through the use of steam in steam cracking furnaces to produce lighter hydrocarbons. The propane dehydrogenation process may be accomplished through different commercial technologies.
