why doesthe temprature fall down towards the end of the fractional distillation
Rectification. By using a rectification column, that has a pressure and temperature difference across it. The column also contains a series of perforated trays, which allows liquid to trickle down and gas to flow up.
fractional distillation is usually use to separate the constituents of crude oil, into petroleum, jet fuel, asphalt, kerosene, and others. Most oil based products are separated by fractional distillation.
you use metromorphism distillation to separate the fractions
Fractional distillation is a manufacturing process that separates the different components (i.e. fractions 1/2 in a chemical mixture according to their different boiling points. The liquid is raised to boiling and vapors pass through a tubular column where temperature is gradually lowered along its length. Components (fractions) with a higher boiling point condense on the column and return to the solution. Fractions with a lower boiling point pass through the column and are collected. Gasoline, kerosene and naphtha are fractions separated from crude oil using fractional distillation.Here's more in simple,the basic principle of fractional distillation is of using the different boiling points of elements(parts) in a compound(a mixture). A fractional distillation process is done in a cylinder which has different compartments having different temperature points. When the mixture is kept in the cylinder, the elements which have the same boiling point as in the compartment it is in, it vaporizes and moves out through a pipe. The mixture goes on vaporizing as the temperature increases and at last all the elements are removed in separated drums where they are condensed and brought back to their normal state.Another way of putting it is:Fractional distillation differs from distillation only in that it separates a mixture into a number of different parts, called fractions. A tall column is fitted above the mixture, with several condensers coming off at different heights. The column is hot at the bottom and cool at the top. Substances with high boiling points condense at the bottom and substances with low boiling points condense at the top. Like distillation, fractional distillation works because the different substances in the mixture have different boiling points.The simplest way is:Fractional distillation is a form of distillation which is used when more than two liquids with different boiling points are to be separated.
methane is the first (and most simple) of the homologous series known as alkanes. It can be formed many ways of which some are --> i) catalytic cracking --> in this process large alkanes are broken down into smaller simpler alkanes and alkenes (of which methane is one) ii) biogas/manure --> in the process of fermentation or anaerobic digestion of manure, about 50% to 75% of the gas released is Methane gas iii) fractional distillation of crude oil/petroleum --> methane is obtained in the top fraction in the fractional distillation of crude oil or petroleum.

cause it goes upand down. thats how it works

fractional distillation is used to separate fuels from crude oils they all have different boiling points so they can be separated easily cracking is when longer chains of hydrocarbons after broken down to make shorter ones which burn more easily.
One of the main sources of all types of energy is from sun.. The sources like fossil fuels, etc r gonna sure disappear some years later.. also its utilisation now also creates serious impact on life of human beings...u can c in many places were its temperature is hike... so installation of other devices for purification s a hard tiring process. so the better option s to use the available source for the purification process will be a good one. so its a advantage...

First of all you have to bend down and suck it :). I Hope It Helped. TROLL.
Hydrocarbons do not break down into their elements when fractionally distilled because the minimum energy necessary for separating the hydrocarbons into their elements is not available from the thermal energy needed to perform fractional distillation.
Fractional distillation is used to turn crude oil into petroleum, and then the products of that (petroleum is one of them) can be broken down into another more flowing substance using a process called cracking, normally done with aliminium oxide as a catalyst
by the process of fractional distillation
First of all there is a fractional distillation column, cold up top hot on bottom, with levels where the vapors can go up but not down. It is heated on the bottom. So when a substance in the vapor reaches a height where the temperature of the 'barrel' is equal to that substance's boiling point, it will condense to form a liquid and collected. It is called fractional distillation. a pic here will help you understand. http://www.msm.cam.ac.uk/doitpoms/tlplib/recycling-polymers/figurescrude_oil_distillation_sml.jpg
