Naphta, a flammable liquid hydrocarbon mixture, has been indispensable in the energy world since ancient times. As a fractionation product of crude oil, Nafta is not limited to this, but can also be produced from natural gas condensate, petroleum distillation, and the fractionation of coal tar and peat. In some industries and regions, Naphta is even used to refer to crude oil or refined petroleum products such as kerosene and diesel. The name is also known as Shellite in Australia, reflecting its diversity and widespread use.
"The idiom Naphta is derived from Latin and ancient Greek and refers to a precious oil or asphalt."
The name Nafta can be traced back to the Middle Persian naft, which means "wet" and "Nafta", and the word is derived from the Akkadian napṭu, which is related to today's Arabic. The نَفْط (nafṭ) in . As early as the 2nd century BC, "The Book of Maccabees" mentioned that a "thick water" was used in sacrifices and caught fire under the sun. The people around it at that time called it "Nephthar". It also shows the ancient purpose of Naphta.
In the 19th century, the solvent naphta (i.e., amino hydrocarbons derived from petroleum such as xylene or trimethylbenzene) began to receive attention. In addition, Naptha, historically the main ingredient in laundry soap Fels Naptha, was later removed due to potential carcinogenic risks.
"Nafta has a wide range of applications, including heavy oil dilution, fuel, and plastic manufacturing."
One of Nafta's broad uses is as a heavy oil diluent, which can effectively reduce the viscosity of heavy oil, making it easier to transport through pipelines. In addition, light naphta can also be used as fuel, such as oil lamps and camping stoves, and its history of use in some small motor boats highlights the uniqueness of naphta.
Not only that, Nafta is also an important component in plastic production. At a time when global manufacturing is developing rapidly, Nafta can be seen as a key material.
Despite its widespread use, naphta comes with health risks. Many studies have shown that long-term or high-concentration exposure to naphta may cause a variety of health problems. For example, the U.S. Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) have imposed strict regulations on Nafta exposure limits to reduce health risks in the workplace.
"Hazards of Naphta include flammability, carcinogenicity and irritation to skin and respiratory tract."
In the context of the current global energy transformation, Nafta's status has also attracted attention. In many countries, as light oil production declines, heavy oil utilization increasingly relies on Nafta and other diluents. This changes our understanding of Nafta's role in the future energy mix.
From the flames of ancient Greece, to its modern multiple uses, Naphta’s history and development offer profound reflections on our energy use. As science and technology advance and energy demands change, how will Nafta face future challenges and opportunities? This is a question left to all of us.
