//]]>, The Process of Fractional Distillation of Crude Oil. The three we'll need for this question are gasoline, kerosene and diesel. I am pleased you enjoyed it - thanks for the vote up. Put the poster up in your classroom or display it on a projector. 5.12 - I recall that fractional distillation of cr. Don't rinse with water as wet steel will rust over time. LPG and 2. (between fuel oil and Bitumen), Real Guns Never Kill Dears by Firing Lead/Large Bullets. Therefore, a fractional distillation is required for this process. Short-chain hydrocarbons Hydrocarbons with few carbon atoms are called 'short-chain hydrocarbons'. [1] [2] In most cases, the distillation is operated at a continuous steady state. Rhys Baker (author) from Peterborough, UK on May 31, 2012: Woops! At temperatures above \(150^\text{o} \text{C}\) the dimer reverts to the monomer through a retro Diels-Alder reaction (driven by the favorable change in entropy, Figure 5.42c). Legal. Also, as all fossil fuels contain carbon, the burning of any fossil fuel will contribute to. In fact, we cannot meet this demand through the products of fractional distillation alone. Due to the different boiling points, crude oil can be separated into fractions (parts) by heating it in a process called fractional distillation. 1.1.7 Ionisation Energy: Trends & Evidence, 1.2.1 Relative Atomic Mass & Relative Molecular Mass, 1.3 The Mole, Avogadro & The Ideal Gas Equation, 1.5.4 Effects of Forces Between Molecules, 1.7.4 Effect of Temperature on Reaction Rate, 1.8 Chemical Equilibria, Le Chatelier's Principle & Kc, 1.8.4 Calculations Involving the Equilibrium Constant, 1.8.5 Changes Which Affect the Equilibrium, 1.9 Oxidation, Reduction & Redox Equations, 2.1.2 Trends of Period 3 Elements: Atomic Radius, 2.1.3 Trends of Period 3 Elements: First Ionisation Energy, 2.1.4 Trends of Period 3 Elements: Melting Point, 2.2.1 Trends in Group 2: The Alkaline Earth Metals, 2.2.2 Solubility of Group 2 Compounds: Hydroxides & Sulfates, 3.2.2 Modification of Alkanes by Cracking, 3.6.1 Identification of Functional Groups by Test-Tube Reactions, 3.7.1 Fundamentals of Reaction Mechanisms, 4.1.2 Performing a Titration & Volumetric Analysis, 4.1.4 Factors Affecting the Rate of a Reaction, 4.2 Organic & Inorganic Chemistry Practicals, 4.2.3 Distillation of a Product from a Reaction, 4.2.4 Testing for Organic Functional Groups, 5. 5.2 Bonding, structure and the properties of matter, 5.2.2 How bonding and structure are related to the properties of substances, 4a Translate information between graphical and numeric form, 4c Plot two variables from experimental or other data, 8.1 Recall that hydrocarbons are compounds that contain carbon and hydrogen only, 8.2 Describe crude oil as: a complex mixture of hydrocarbons; containing molecules in which carbon atoms are in chains or rings (names, formulae and structures of specific ring molecules not required); an important source of useful substances, 8.3 Describe and explain the separation of crude oil into simpler, more useful mixtures by the process of fractional distillation, 8.4 Recall the names and uses of the following fractions: gases, used in domestic heating and cooking; petrol, used as fuel for cars, kerosene, used as fuel for aircraft; diesel oil, used as fuel for some cars and trains; fuel oil, used as fuel for large, 8.5 Explain how hydrocarbons in different fractions differ from each other in: the number of carbon and hydrogen atoms their molecules contain; boiling points; ease of ignition; viscosity; and are mostly members of the alkane homologous series, 8.15 Recall that petrol, kerosene and diesel oil are non-renewable fossil fuels obtained from crude oil and methane is a nonrenewable fossil fuel found in natural gas, 9.10C Recall the formulae of molecules of the alkanes, methane, ethane, propane and butane, and draw the structures of these molecules, showing all covalent bonds, 9.11C Explain why the alkanes are saturated hydrocarbons, 2.4 Predict the physical state of a substance under specified conditions, given suitable data, Methods of separating and purifying substances, 2.6 Interpret melting point data to distinguish between pure substances which have a sharp melting point and mixtures which melt over a range of temperatures, C6.1h describe the separation of crude oil by fractional distillation, C6.1i explain the separation of crude oil by fractional distillation, C6.1k recall that crude oil is a main source of hydrocarbons and is a feedstock for the petrochemical industry, C6.1l explain how modern life is crucially dependent upon hydrocarbons and recognise that crude oil is a finite resource. This is the first step in the processing of crude oil, and it is considered to be the main separation process as it performs the initial rough separation of the different fuels. Long chain hydrocarbons have lots of intermolecular forces (think of lots of necklaces getting tangled in a jewellery box) making them difficult to separate. Structures, but not isomers, of hexane, heptane, octane, cyclohexane and 2,2,4-trimethylpentane (iso-octane) to be considered. These write-on worksheets will ask learners to use their knowledge of crude oil in an applied context. As shorter chain molecules are more flammable (and burn with a cleaner flame) these are in higher demand. Diagram of a fractional distillation tower, showing where the different fractions will condense. http://upload.wikimedia.org/wikipedia/commons/thumb/6/6e/Crude_Oil_Distillation-en.svg/260px-Crude_Oil_Distillation-en.svg.png, http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_pre_2011/rocks/fuelsrev3.shtml, https://energyeducation.ca/wiki/index.php?title=Fractional_distillation&oldid=10219. 1c Use ratios, fractions and percentages. The full names of the fractions are petroleum gas, naphtha, gasoline, kerosene, diesel, lubricating oil, fuel oil, and tar. By Catherine Smith2023-01-03T09:00:00+00:00, Use this poster and classroom activity to ensure your 1416 students understand this important industrial application of separation. Fractional distillation is a physical process and not a chemical one, so no covalent bonds are broken. Fuels for ships 8. As you go up the fractionating column, the hydrocarbons have: Natural gas mainly consists of methane. Legal. It is used in domestic boilers, cookers and Bunsen burners, as well as in some power stations. Each fraction has a different use. A-Level Practical Skills (A Level only), 8.1 Physical Chemistry Practicals (A Level only), 8.2 Inorganic Chemistry Practicals (A Level only), 8.3 Organic Chemistry Practicals (A Level only), Crude oil is currently the world's main source of organic chemicals, As a mixture, it isnt a very useful substance, but the different hydrocarbons that make up the mixture, called fractions, are useful, with each fraction having different applications, It is a mixture of mostly alkanes, unbranched and branched chain, Each fraction consists of groups of hydrocarbons of, Hydrocarbons of similar chain length have similar boiling points, The fractions are separated from each other in a process called, The size and length of each hydrocarbon molecule determines in which fraction it will be separated into, The size of each molecule is directly related to how many carbon and hydrogen atoms the molecule contains, Fractional distillation is carried out in a, Crude oil enters the fractionating column and is heated so, The different fractions condense at different heights according to their, The crude oil contains small amounts of other compounds, Some of these compounds may contain sulfur, and when burned sulfur dioxide can be produced. At the bottom are the "residuals" that contain heavy tars too dense to rise up the tower, including bitumen and other waxes. Please see the video below from fuse school to see how fractional distillation works. The longer chain hydrocarbons have a higher boiling point and condense towards the bottom of the column where it is hotter.

After this rough refinement, individual fuels may undergo more refinement to remove any contaminants or undesirable substances, or to improve the quality of the fuel through cracking. The fractions can be processed to produce fuels and feedstock for the petrochemical industry.
