Hydrocarbons should not be heated to too high
temperature due to cracking reactions that take
place above about 400 °C. Coke deposits on piping and equipment increase maintenance costs
and reduce process unit run-time. Therefore
crude distillation bottom (residue) is further processed in a vacuum column to recover additional
distillates, light and heavy vacuum gasoils as
feedstock to cracking units or lube-oil processing. Three types of vacuum towers are used: dry
(no steam), wet without stripping and wet with
stripping.

How is crude oil separated into fractions?
The separation is possible by fractional distillation.
Why is crude oil separated by fractional distillation?
Petroleum is a mixture of various useful constituents and cannot be used directly,so to use it we have to seperate petroleum by a method called fractional distillation of petroleum.
How is crude oil separated?

How is naphtha produced from crude oil?
fractional distillation
How is crude oil separated into fractions?
The separation is possible by fractional distillation.
What does it involve fractional distillation of crude oil?
This is the separation of crude oil components based on the differences between boiling point temperatures.
How are substnces taken from crude oil?
The refining of crude oil requires separation, distillation, reforming, cracking and related processes to resolve the mixture of components into products.
What method of separation is used in the refinery to separate crude oil into its constituents such as petrol kerosene diesel?
Fractional distillation ( i think)

What two industrial uses of distillation and what components of mixtures are separated in each use?
Separation of pure components from a mixture.
What is the name of the process that separates crude oil into more useful substances?
Crude oil is separated by fractional distillation. The components of crude oil are separated by a process which is known as fractional distillation. Crude oil is made of different components whose sizes, weights and boiling temperatures are different from each other. When the crude oil is heated with high pressure steam at a high temperature, it boils and forms vapour. The vapour enters a fractional distillation column and settled in the trays of the column. The trays have holes in them which raise the contact time among the vapour and liquids. The vapour rises in the column and cools, the hotter substances settle at the bottom of the column and the cooler substances rise to the top of the column. The substances in the vapour condense and the fractions of liquid collect in the tray and pass to condensers and storage tanks.
Distillation of crude oil can produce?
distillation of crude oil can produce, asphalt, heating oil, diesel oil.
What is distllation?
Distillation is the separation of different fractions of a component. This is usually done by heating the component and removing the fractions based upon their boiling points. An example of this could be distillation (or fractionation) of crude oil into different fractions such as heating oil, diesel, jet fuel, naphtha (a component of gasoline), or asphalt. All of these components have specific boiling points and therefore their separation from the crude oil can be closely controlled.
What is the steps of the fractional distillation of crude oil?
The major steps include:Desalting - removing salt, water, dirt and other impuritiesCrude and vacuum distillation - start separating the crude oil into separate productsConversion - modifying the composition of the productsBlending - putting together measure amounts of products to make something that does a specific job
Can you give me a sentence with the word distillation in it?
distillation of crude oil is a continuous process.
What are By products of distillation of crude oil?
