The gases in air can be separated from one another through a process known as the fractional distillation of liquid air. This is a process that converts air into a liquid form and then allows it to be portioned out into layers and separated from one another. Because pure oxygen and nitrogen have a number of applications, this is a useful technique.Continue Reading
Fractional distillation is a process that can separate gases from one another if they can be converted into a liquid form. To perform this separation on air, it must be cooled to a very low temperature so that it liquefies. Once this is done, the air can be passed into the bottom of a fractionating column. This column slowly raises the temperature until the oxygen and nitrogen in the air are separate from one another. From there, two tubes separately pipe off the gases.
This process can be repeated on the oxygen because in many cases, there are still trace amounts of argon found in the oxygen. Pure nitrogen, oxygen and argon can be removed from the air by the end of the final fractional distillation. The nitrogen is used in a number of different settings, especially the food and grocery industries.Learn more about Chemistry
Nitrogen gas is primarily obtained by condensing air into a liquid and removing the liquid nitrogen in a process known as fractional distillation. There are other methods to obtain nitrogen, but this is the most common.Full Answer >
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.Full Answer >
Diesel fuel is a flammable mixture of hydrocarbons made by the fractional distillation of petroleum, which occurs at between 200 to 360 degrees Celsius, which is 392 to 680 degrees Fahrenheit. The mixture is mainly comprised of alkanes, cycloalkanes and aromatic hydrocarbons possessing between 12 and 20 carbon atoms.Full Answer >
Fractional distillation involves boiling crude oil so that the various types of hydrocarbon molecules present vaporize, each in turn. The vapors are then condensed into separate batches according to type.Full Answer >
