    What is Gasoline

    Gasoline Gasoline (also referred to as motor gasoline, petrol in Britain, benzine in Europe) is a mixture of volatile, flammable liquid hydrocarbons derived from petroleum that is used as fuel for internal combustion engines such as occur in motor vehicles, excluding aircraft The boiling range of motor gasoline falls between –1°C (30°F) and 216°C (421°F) and has the potential to contain several hundred isomers of the various hydrocarbons—a potential that may be theoretical and never realized in practice. The hydrocarbon constituents in this boiling range are those that have 4–12 carbon atoms in their molecular structure and fall into three general types: (1) paraffins (including the cycloparaffins and branched materials), (2) olefins, and…

    Oil Refinery Processes

      Process Objective: To distill and separate valuable distillates (naphtha, kerosene,diesel) and atmospheric gas oil (AGO) from the crude feedstock. Primary Process Technique: Complex distillation Process steps: –Preheat the crude oil feed utilizing recovered heat from the product streams –Desalt and dehydrate the crude using electrostatic enhanced liquid/liquid separation (Desalter) –Heat the crude to the desired temperature using fired heaters –Flash the crude in the atmospheric distillation column –Utilize pumparoundcooling loops to create internal liquid reflux –Product draws are on the top, sides, and bottom. Typical Yields and Dispositions: product & Yield in wt% of Crude Light Ends 2.3 Light Naphtha  6.3 Medium Naphtha 14.4 Heavy Naphtha 9.4 Kerosene  9.9 Atmospheric Gas Oil…

    what is Naphtha

    what is Naphtha Naphtha is a liquid petroleum product that boils from about 30°C (86°F) to approximately 200°C (392°F), although there are different grades of naphtha within this extensive boiling range that have different boiling ranges . The term petroleum solvent is often used synonymously with naphtha. On a chemical basis, naphtha is difficult to define precisely because it can contain varying amounts of its constituents (paraffins, naphthenes, aromatics, and olefins) in different proportions, in addition to the potential isomers of the paraffins that exist in the naphtha boiling range. Naphtha is also represented as having a boiling range and carbon number similar to those of gasoline a precursor to gasoline. The so-called petroleum ether solvents are specific-boiling-range naphtha as is…
