Why different fractions of crude oil are collected at different temperatures?

Because crude oil is a mixture of different chemicals - mainly hydrocarbons - that have different evaporation temperatures. Roughly speaking, when the crude is heated, its temperature rises until it reaches the lowest vaporisation temperature. The temperature then remains more or less steady as the heat input is used as the latent heat of vaporisation for the relevant compound. When [almost] all of that compound has evaporated, the temperature starts rising again until it reaches the next varorisation temperature, and so on.

What is the difference between birth rate and crude birth rate?
Crude birth rate is how many live children are born. Crude death rate is how many people die. Crude death minus crude birth is the net gain (or loss) and is called the birth rate. It represents whether or not deceased people are "replaced".
What is true about I statement?
They made be crude or sophisticated
What does Black Gold refer to?
crude oilAnswerit is oil also know as Texas tea
What is the difference between an intelligent guess and crude guess?
a crude guess is just a mere guess while the intelligent guess is likely to happen due to your experience
What is the Difference between crude death rate and actual death rate?
Death Rate is the actual rate of death where Crude Death Rate is a guess on the death rate.
Explain how the different chemical compounds in crude oil are separated?
Crude oil is distilled, producing different fractions at different temperatures.
Why is a thermometer needed when separating crude oil?
Because different fractions separate at different temperatures.
Why the different fraction of crude oil are collected at different temperature?
Oils collected at different temperatures produce different oils, and distillate fuels. Gasoline, diesel fuel, lubricating oils, solvents are all collected at different specific temperatures.
How is it possible to separate crude oil substances?
Through a process known as fractional distillation, also called cracking.The oil is heated and vapours of the various components are given off. The different vapours condense at different temperatures and these fractions are collected.
What is a process where a substance is heated evaporated and cooled in a collection chamber and the different fractions of crude oil distill at different temperatures?
Distillation
Why are some fractions of crude oil cracked?
Oils collected at different temperatures produce different oils, and distillate fuels. Gasoline, diesel fuel, lubricating oils, solvents are all collected at different specific temperatures.
What is the Important of cracking?
The importance of cracking is REALLY important ! Due to the presence of the hydrocarbon atoms present in the fossil fuels, the importance is really beneficial for the people who work in the petroleum industry. As a result of this, the fractions of crude oil are collected at different temperatures as biodegradable polymers. =]
How is crude oil separated into different fractions?
you use fractional distillation! basically, all the different substances in crude oil have different boiling points, and the column which is used to do fractional distillation has stages with different temperatures. when the substance reaches its boiling point temperature in the column, it turns into liquid and settles there, away from other fuels.
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 a process in which crude oil can be separated?
Ditillation at different temperatures
How do you get oil out of the ground?
Oil is pumped out of the ground by first locating the oil and determining how far below the ground it is. A large drill is then used to drill to where the oil is and a rig is used to pump the oil out of the ground to be sent off to the refinery.
Why crude oil is separated into different fractions?
Unless you own a cargo ship and run it on crude oil - some operators do - it has to be separated into fractions before it's usable.
