» » Naphtha


Naphtha is a cut of the crude oil. The naphtha contains a group of organic compounds with a chain length of 5 to 9 carbon atoms. Usually, naphtha is used to produce more valuable products such as gasoline. naphtha is divided into two main types: aromatic and aliphatic. Eating Naphtha causes burning of the throat, mouth, and nose.

Nafta is a combination of combustible hydrocarbons, which include certain hydrocarbons with flammability and specific volatility. For example, products of the distillation of crude oil or coal tar. Nafta is one of the light petroleum products and is usually produced in the refinery in the form of light naphtha and heavy naphtha. Nafta is principally used as a feed for other units to produce high-octane gas (catalytic reforming process). It is also used in the chemical industry for the production of olefins in the Steam Cracker unit and also as a solvent. Nafta comes from Latin and Greek. This term was used in ancient Greek as any kind of oil and bitumen.  


Nafta is a fundamental ingredient in the petrochemical industry. Nafta gets used to produce gasoline. Naphtha is also used as the solvent.  

Production methods: 

Nafta is divided into two main types: aromatic and aliphatic. Aliphatic naphtha consists of paraffinic hydrocarbons and paraffinic cyclones (naphthenes), which is obtained directly from crude oil by distillation. Aromatic naphtha consists of aromatics, alkyl benzenes, which are rarely obtained directly from crude oil and require refinement. In general, naphtha is produced by the following methods: 

1- the Direct-run product of distillation of crude oil. 

2. Extraction by solvent 

3. Hydrogenation of unsaturated compounds 

4. Polymerization of unsaturated compounds (olefin) 

5. Alkylation process 

Of course, naphtha can also be obtained from the combination of these methods.  

Safety information: 

When naphtha is contacted by the skin, it quickly evaporates. In practice, it causes dry skin irritation. However, when kept on the skin for a long time, it can dissolve the skin's fats and dryness. Swallowing it causes burning of the mouth, throat, and chest and abdominal distension, nausea, and vomiting. Reducing the effectiveness of the central nervous system, such as anesthetics, may also be observed.
