Distillation is a method of separating mixtures based on differences in volatility of components in a boiling liquid mixture.
Fractionation is a separation process in which a certain quantity of a mixture (solid, liquid, solute, suspension or i) is divided up in a number of smaller quantities (fractions) in which the isotope composition varies according to a gradient.

What is the driving force of different unit operations?
The driving force of different unit operations can vary depending on the specific process involved. For example, in distillation, the driving force is the difference in vapor pressure between the components being separated. In filtration, the driving force is the pressure difference across the filter medium. In heat exchangers, the driving force is the temperature difference between the two fluids exchanging heat.
What is the difference between simple distillation and fractional distillation?
Simple distillation refers to the "simple" separation of a solid and a liquid by evaporating the liquid and collecting it after it passes through a condenser to be changed into a liquid state. Fractional distillation refers to the more complex way of separation, usually involving a liquid/liquid mixture (eg. ethanol and water). these can be separated since they both have different boiling points. When this mixture is heated the ethanol having the lowest boiling point boils off first, followed by the water. However the fractional coulomb condenses both gases back into liquid, and fall back in the flask, with time the ethanol gains enough energy to over come the fractional coulomb (this happen before the water does this since ethanol has a LOWER boiling point) and pass through the condenser, changes into a liquid and is collected.
What is the relation between the path difference and phase difference?
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
What is the equation for calculating the phase difference between two waves?
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
What is the formula for calculating the phase difference between two waves?
The formula for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
What is fractionation column used for?
The fractionation column is used to separate components of a liquid by distillation.
How the process fractionation takes place?
Distillation
difference between simple and fractional distillation?
The key difference between fractional and simple distillation is that fractional distillation is used when the components in the mixture have closer boiling points, while simple distillation is used when the components in the mixture have a large difference in their boiling points
In what situation would you use fractional distillation over simple distillation?
You would use simple distillation when the two products you are trying to separate have large difference in boiling points. Fractional distillation is needed when the two products have very close boiling points (like Hexane and toluene). In petroleum refining, the word "fractionation", not "fractional distillation" is used, often interchangeably with "distillation". When we have a crude mixture of different compounds which have very minor difference in their boiling points and cannot be separated simple distillation, then fractional distillation is used. Differenciation of components of petroleum is done by this process
When you use distillation?
when there is less density difference between two liquids of mixture & proper difference in boiling point distillation can be used.
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 the process that separates a mixture based on the boiling points?
The process that separates a mixture based on boiling points is called fractional distillation. It involves heating the mixture to evaporate the components, then cooling and condensing them back into liquids based on their boiling points. This allows for separation of the components based on the temperature at which they vaporize.
What is the process that separates components from mixtures?
The process that separates components from mixtures is called separation. This can involve techniques such as filtration, distillation, chromatography, or evaporation, depending on the properties of the components and the mixture. Each technique exploits the physical or chemical differences between the components to isolate them.
What is the technique in which cells are broken into pieces and the different cell parts are separated?
The cell fractionation
What type of properties does distillation use to separate homogeneous mixtures?
The difference between boiling points is exploited.
What is the name of the processes used to obtain fractions from crude oil?
The processes used to obtain fractions from crude oil are called distillation and fractional distillation. Distillation involves heating the crude oil to separate it into different components based on their boiling points, while fractional distillation further refines the process by separating the components into more specific fractions.
