Why do the higher boiling fractions in a fractionating column settle at the lower levels?
They are denser.
What is a fractionating column?
This is an installation used for separation by distillation.
How fractionating column made?
why does temprature fall down toward the end of the fractional column
What is the name of the column used to separate crude oil into its various components?
Fractionating column. The process is fractional distillation
What is the purpose of the beads in fractionating column?
The surface area is increased by the glass beads.
Why does LPG exit from the top of the fractionating column?
The boiling point is lower.

What is the function of the fractionating column in fractional distillation?
The fractionating column is usually filled with glass or plastic beads. These beads improve the separation between the liquids being distilled. The reason that fractional distillation gives better separation between the liquids is because the glass beads in the fractionating column provide "theoretical plates" on which the refluxing liquid can condense, re-evaporate, and condense again, essentially distilling the compound over and over. The more volatile liquids will tend to push towards the top of the fractionating column, while lower boiling liquids will stay towards the bottom, giving a better separation between the liquids.
How crude oil is separated into useful fraction?
Crude oil is separated into different substances with similar boiling points. The substances in crude oil can be separated using fractional distillation. The crude oil is evaporated and its vapours are allowed to condense at different temperatures in the fractionating column. Each fraction contains hydrocarbon molecules with a similar number of carbon atoms
How are fractions separated in a fractionating column?
Fractionation is based on the differences between boiling points of components.
What is the method used to separate fractions of crude oil?
Fractional Distillation. Performed in a fractionating column. Heat is applied to the crude oil and it vaporises. Fractions with different boiling points rise to specific heights within the fractionating column, where they are condensed and extracted.
What is the top of an oil fractionating column is?
The bottom is where the compounds with the highest boiling points are found. The ones with the lowest boiling points will be found at the top of the column.
What fraction is found at the top of the fractionating column?
numerator

How does a fractionating column separate crude oil into different parts?
The fractionating column takes advantage of the fact that the different parts (fractions), which form the mixture known as crude oil, boil (or evaporate) at different temperatures. The fractionating column is effectively an advanced distillation process. The bottom part of the column is the hottest part where heavy fractions such as tar do not evaporate, but lighter fractions will boil off and travel upwards through the column. The top part of the column is the coolest part where only the lightest fractions form a vapour. At various points between the top and bottom, the different fractions condense into liquids at different temperatures and can be drawn off in purified liquid form.
What is the best fractionating column for ethanol distillation using lab glass?
