What is the composition of naphtha?

What is the composition of naphtha?

Naphtha contains varying amounts of paraffins, olefins, naphthene constituents, and aromatics and olefins in different proportions, in addition to potential isomers of paraffin that exist in naphtha boiling range.

What is naphtha?

Naphtha is a flammable liquid made from distilling petroleum. It looks like gasoline. Naphtha is used to dilute heavy oil to help move it through pipelines, to make high-octane gas, to make lighter fluid, and even to clean metal. Naphtha is created by distilling petroleum, and it’s a component of gasoline and kerosene.

What is naphtha petroleum hydrotreated heavy?

Hydrotreated heavy naphtha (petroleum) is a complex mixture of hydrocarbons ob- tained by treating a mineral oil fraction with hydrogen in the presence of a catalyst. According to the definition of the CAS number, it is a mixture free of aromatic hydrocarbons (ACCOP 2001, 2004).

What is solvent naphtha?

A complex combination of hydrocarbons obtained from distillation of aromatic streams. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C9 through C16 and boiling in the range of approximately 165°C to 290°C (330°F to 554°F).

What is heavy naphtha?

Heavy naphtha is a distillation cut primarily made up of material roughly the same density as finished gasoline. Heavy naphtha molecules typically have from 7-9 carbon atoms. Its boiling range can be from 180F to 330F. Most of the heavy naphtha in a refinery comes directly from the atmospheric distillation unit.

Is naphtha the same as naphthalene?

As nouns the difference between naphthalene and naphtha is that naphthalene is a white crystalline hydrocarbon manufactured from coal tar; used in mothballs while naphtha is (dated) naturally-occurring liquid petroleum.

What is aliphatic naphtha?

Aliphatic naphthas are a liquid hydrocarbon mixture. Also known as aliphatic solvent naphthas, the term covers a category of chemicals derived from petroleum distillates and natural gas condensates. These chemicals are clean and flammable by nature, and, as such, can be used for a variety of purposes.

What is VM and P naphtha?

Sterling VM & P Naphtha is a highly volatile mixture that acts as a fast-drying paint thinner for oil-based paints, enamel, and varnish. Dries quickly, so it’s not recommended for cleaning brushes. VM & P stands for ‘Varnish Makers and Painters’.

What is Heavy straight run naphtha?

Heavy straight run naphtha (petroleum) A complex combination of hydrocarbons produced by distillation of crude oil. It consists of hydrocarbons having carbon numbers predominantly in the range of C6 through C12 and boiling in the range of approximately 65°C to 230°C (149°F to 446°F).

What is the difference between heavy and light naphtha?

One source distinguishes by boiling point: Light naphtha is the fraction boiling between 30 °C and 90 °C and consists of molecules with 5–6 carbon atoms. Heavy naphtha boils between 90 °C and 200 °C and consists of molecules with 6–12 carbon atoms.

Is naphtha aliphatic or aromatic?

“Heavy” Naphtha has a boiling range of 150-200°C. Naphtha contains both aliphatic and aromatic hydrocarbons. Essential Oils are oils or solvents that are distilled from natural, organic sources like flowers or wood.

What is pure light naphtha?

Light naphtha can refer to either a finished product used as a petrochemical feedstock or a distillation cut commonly called light straight run naphtha. It is composed of pentane and slightly heavier material. Light naphtha from NGL fractionation is often called natural gasoline or pentanes plus.

What is the chemical formula of naphtha?

Molecular Formula. Molecular Weight. Naphtha. C 7 H 18. 102.21782. Also see… » Atomic number of different elements. » Atomic weight of different elements. » Density of different elements.

What are the main uses of naphtha?

Uses and Safety. As mentioned above, naphtha is commonly used as a solvent. It is used in hydrocarbon cracking, laundry soaps, and cleaning fluids. Naphtha is also used to make varnishes, and sometimes is used as a fuel for camp stoves and as a solvent (diluent) for paint. Although naphtha has many uses, some forms of it can be dangerous.

What is the density of naphtha?

Naphtha weighs 0.74 gram per cubic centimeter or 740 kilogram per cubic meter, i.e. it’s density is equal to 740 kg/m³. The density was measured at 20°C (68°F or 293.15K) at standard atmospheric pressure.

What is Naptha for?

Naptha is commonly used as an aid in the refinement and distillation processes of crude oils into more efficient products, as well as a component of several types of gasoline. Its use is generally preferred over other types of crude gas oil.
