How is crude oil separated into fractions?
Crude oil is separated into fractions through a process called fractional distillation. This involves heating the crude oil to different temperatures in a fractionating column, which separates it into different components based on their boiling points. The lighter fractions with lower boiling points rise to the top, while the heavier fractions with higher boiling points collect at the bottom.
What is the physical process occurring that allows fractions to be collected at different levels?
Fractionation is based on the differences in boiling points of components in a mixture. As the mixture is heated, each component vaporizes at its specific boiling point and rises through a fractionating column. Components with lower boiling points rise higher in the column before condensing and being collected at different levels, allowing for separation based on boiling point differences.
What is it called when you separate liquids by boiling and condensing them at different temperatures?
Fractionation. One other specialized application is called distillation. I'd put it differently. Distillation refers to any boil and condense process. Alcoholic spirits are distilled and in many cases the idea is not to separate the components too much. Simple distillation does separate liquids at different temperatures though you would not normally refer to it as fractionation. To do fractionation effectively the cycle must be repeated many times, which can be done automatically with a fractionating column. The components that emerge in succession are called fractions.
What is a long slanting tube used in the distilling process?
A long slanting tube used in the distilling process is typically known as a "reflux column" or "fractionating column." It is designed to improve the separation of different components in a mixture by allowing vaporized substances to condense and then re-vaporize before exiting the column. This process helps to achieve higher levels of purity in the distillate.
Which has a higher boiling point 0.50 NaCl or 0.50 MgCl2?
The magnesium chloride solution has a higher boiling point.

Why the chemicals in crude oil separate out in a particular order?
Chemicals in crude oil separate based on their boiling points. When crude oil is heated in a distillation column, the components with lower boiling points vaporize first and rise to the top of the column. As the temperature increases, components with higher boiling points gradually separate out at different levels in the column. This process is known as fractional distillation.
What is a process column?
A process column is a vertical cylinder in which a reaction takes place. The reaction is commonly one of filtering or selection, as measured by ionic charge; or molecular size and so on. Often an ion-exchange resin is used as the process material. A particular type of process column is the fractionating column, beloved of the petrochemical industry. These are tens of metres high, and rely on the fact that as the pressure reduces up the column, the boiling point of the (liquid) will change. Thus the high b.p material comes off lower down, and lower b.p. come off at higher levels.
What is the process of fractional distillation?
If you have a liquid which is a mixture of different chemicals which have different boiling points, you can boil them off, one chemical at a time, capturing the resulting vapor and condensing it into a pure chemical.
Why are fractionating towers in refineries always tall?
such towers are basically to separate the liquids having boiling points very closer (fractional distillation) so the length of the tower is useful for separation of condensing material and evaporating material, higher is the length of the tower more purity of a fraction we get.
How does separation occur with distillation?
The various components of a mixture will boil at different temperatures and pressures, and this simple fact underlies the Fractionating Columns seen in refineries. Various compounds boil as above, and may be 'tapped off' at the appropriate point up the column.
How do you separate mixture of nitrogen and oxygen?
Cool the gases to a temperture between the boiling points of the two gases. Nitrgen condenses to a liquid at a higher temperaturte than oxygen. So liquid nitrogen is drawn off and gaseous oxygen remains.

What is the residue which is not recovered in distillation process of gasoline?
The residue not recovered in the distillation process of gasoline is known as bitumen or asphalt. This thick, heavy material has a higher boiling point than gasoline and remains at the bottom of the distillation column after the desired gasoline fractions have been collected.
What estimation of the volume of liquid boiling below 85 celsius with and without column in the distillation curves?
In distillation, the column helps separate liquids based on their boiling points. Without a column, the volume of liquid boiling below 85 degrees Celsius would include components boiling at or below that temperature. With a column, the separation process would be more efficient, resulting in a higher purity of the component boiling below 85 degrees Celsius.
Why is diesel fuel removed at the bottom of a distillation tower?
Diesel fuel is removed at the bottom of a distillation tower because it has a higher boiling point compared to lighter fractions like gasoline. In the distillation process, different fractions are separated based on their boiling points, with heavier components collecting at the bottom. This allows for the efficient separation and collection of diesel fuel.
