What is heavy naphtha used for?
Heavy naphtha hydrotreating is usually used to remove the impurities so that the hydrotreated naphtha can be introduced to the catalytic reformer. The expensive platinum based catalyst used in the reformer is sensitive to poisoning by such impurities.
What is the full form of naphtha?
Naphtha (/ˈnæpθə/ or /ˈnæfθə/) is a flammable liquid hydrocarbon mixture. Mixtures labelled naphtha have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat. In different industries and regions naphtha may also be crude oil or refined products such as kerosene.
Are there different types of naphtha?
Naphtha is divided into two main types, aliphatic and aromatic. The two types differ in two ways: first, in the kind of hydrocarbons making up the solvent, and second, in the methods used for their manufacture.
How much does naphtha cost?
The average price of naphtha globally stood at 382 U.S. dollars per metric ton in 2020. By July 2021, naphtha’s price had increased to approximately 598 U.S. dollars per metric ton.
Why is naphtha so important?
Naphtha is primarily used as a base material for the production of high-grade gasoline by means of the catalytic reforming process. Naphtha is also a valuable feedstock for the petrochemical industry and its most important process, steam cracking.

What does naphtha dissolve?
Mineral spirits will dissolve only paint that is still fresh. Naphtha is a petroleum solvent similar to mineral spirits but with a greater volatility; it is used chiefly as a paint thinner or a cleaning agent. Naphtha is a more powerful solvent than mineral spirits, so less is needed to thin the same amount of paint.
Where do you get naphtha?
Shale naphtha is obtained by the distillation of oil produced from bituminous shale by destructive distillation. Petroleum naphtha is a name used primarily in the United States for petroleum distillate containing principally aliphatic hydrocarbons and boiling higher than gasoline and lower than kerosene.
What happens if you breathe in naphtha?
* Naphtha can affect you when breathed in and by passing through your skin. * Contact can irritate and burn the skin and eyes. * Breathing Naphtha can irritate the nose and throat. * Exposure to Naphtha can cause headache, dizziness, nausea and vomiting.
Is naphtha the same as paint thinner?
Naphtha is a petroleum solvent similar to mineral spirits but with a greater volatility; it is used chiefly as a paint thinner or a cleaning agent. Naphtha is a more powerful solvent than mineral spirits, so less is needed to thin the same amount of paint.
What kind of liquid is full range naphtha?
Naphtha is a colourless to reddish-brown volatile aromatic liquid, very similar to gasoline. In petroleum engineering, full range naphtha is defined as the fraction of hydrocarbons in petroleum boiling between 30°C and 200°C. It consists of a complex mixture of hydrocarbon molecules generally having between 5 and 12 carbon atoms.
What’s the difference between light and heavy naphtha?
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 carbons. Naphtha is used primarily as feedstock for producing high octane gasoline (via the catalytic reforming process).
Which is the best balance for a heavy naphtha reformer?
The heavy naphtha analysis provides balances for heavy naphthenic / rich naphtha that is good feed for heavy naphtha reformers, and typically boils between 160⁰F and 370⁰F (C11). Heavy naphtha balances exclude heavy naphtha that has low N+A, content below approximately 35%.
How many ppm of naphtha is dangerous to humans?
At levels of 1000 ppm, which equates to 10% of the lower explosive limit, naphtha is immediately dangerous to life and health. ^ Christian Gizewski ( Berlin Institute of Technology ).
