Why does the quiz say bitumen is used to fuel cars? Copyright The Student Room 2023 all rights reserved. This gas is a cause of acid rain. Victoria [student] on September 10, 2019: i have to do a presentation about this and it helped a lot :) THANKS!!! 5.7 - describe how the industrial process of fract. Small molecules have very small forces of attraction between them and are easy to break by heating. Paraffin wax, diesel, lubricating oil, gasoline, kerosene and naphtha are the substances that crude oil contains. Fuels for ships 8. Due to the different boiling points, crude oil can be separated into fractions (parts) by heating it in a process called fractional distillation. Cracking converts large alkane molecules into smaller, more useful, alkane and alkene molecules. Crude oil is vapourised and fed into the bottom of the fractionating column. The separation of various components of crude oil is one of the very common examples of fractional distillation in the industry. 2) They are saturated compounds. Out of all the fractions, bitumen has the highest boiling point and is collected at the very bottom of the fractionating column. I am pleased you enjoyed it - thanks for the vote up. It mainly consists of hydrocarbons - molecules made only of carbon and hydrogen atoms. As the vapour rises up the column, the temperature falls. It is used in domestic boilers, cookers and Bunsen burners, as well as in some power stations. The resulting vapour then rises through the vertical column. The shorter chain hydrocarbons have a lower boiling point and remain as gases higher up, only condensing once a lower temperature is reached near the top of the column. 2.5.2 define a homologous series as a family of organic molecules that have the same general formula, show similar chemical properties, show a gradation in their physical properties and differ by a CH group; 2.5.3 recall that a hydrocarbon is a compound/molecule consisting of hydrogen and carbon only; 2.5.4 recall the general formula of the alkanes and the molecular formula, structural formula and state at room temperature and pressure of methane, ethane, propane and butane; 2.5.6 describe and explain the separation of crude oil by fractional distillation; 2.5.7 describe the fractions as largely a mixture of compounds of formula CH, which are members of the alkane homologous series, and recall the names and uses of the following fractions: refinery gases used for bottled gases; petrol used as a fuel, Unit C2: Further Chemical Reactions, Rates and Equilibrium, Calculations and Organic Chemistry.

Fractional distillation is also used to separate nitrogen and oxygen from air. The lighter fractions are able to rise higher in the column before they are cooled to their condensing temperature, allowing them to be removed at slightly higher levels. 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. The distilling pot will need to be heated much more vigorously than with a simple distillation, as there is a greater distance for the vapors to travel before reaching the condenser. He did this to warn a lady about the dangers of smoking. Stewart specialises in Chemistry, but has also taught Physics and Environmental Systems and Societies. 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. Hoboken, NJ, U.S.A.: John Wiley & Sons, 2006. 5.8 - Recall the names and uses of the main fracti. Very good. When it comes to the fractional distillation of crude oil, steamed hot water is used to boil the liquid in order to separate the distillates, and because crude oil is a complex liquid, there are many distillates that are obtained over a range of temperatures; the most popular are petrol, diesel, gas oil or red diesel and kerosene. (between Gasoline and Kerosine), how about real guns NEVER kill deer by firing LARGE (lubricating oil) bullets..:\, What about lubricating fraction? BBC - GCSE Bitesize: Fractional distillation.

Before using the column, remove this wad as it may interfere with the passage of vapors (Figure 5.44a). Our world revolves around crude oil, and yet it is completely useless until it goes through several physical and chemical processes. Recall that crude oil is a main source of hydrocarbons and is a feedstock for the petrochemical industry. Crude oil is the remains of an ancient biomass consisting mainly of plankton that was buried in mud. The intermolecular forces between molecules are broken as the crude oil is heated.You do not need to memorise the fractions, you just need to understand the principle of what is happening during the process, and why it is used. Describe, explain and exemplify the processes of fractional distillation. The majority of our fuels and plastics are derived from oil. Catherine is head of science at the Hinckley School, an 1118 academy in Leicestershire. Some properties of hydrocarbons depend on the size of their molecules, including boiling point, viscosity and flammability.

The majority of the use we get out of crude oil is as fuel. 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. does anyone have a good mneumonic to remember this? 4.10.1 Using the earth's resources and obtaining potable water, 4.10.1.1 Using the earth's resources and sustainable development. G.Boyle, B.Everett, S.Peake, J.Ramage. The longer chain hydrocarbons have a higher boiling point and condense towards the bottom of the column where it is hotter. In fact, we cannot meet this demand through the products of fractional distillation alone. (PDF) Distillation process of Crude oil - ResearchGate Fractional distillation is the process of separating crude oil into groups of hydrocarbons with similar numbers of carbon atoms. //, The Process of Fractional Distillation of Crude Oil. Use the differentiated synoptic questions to consolidate prior learning on the topics of bonding, structure and the properties of matter and changes of state. What is Fractional Distillation? | Definition from Seneca Learning Crude oil can be separated into different fractions using fractional distillation. For alkynes only ethyne to be considered. 3.2.1 Fractional Distillation of Crude Oil. As you go up the fractionating column, the hydrocarbons have: Natural gas mainly consists of methane. These physical processes do not involve chemical reactions and no new substances are made. Mnemonic for the Fractional Distillation of Crude Oil Atmospheric crude distillation unit. New cars and vans powered wholly by petrol and diesel will not be sold in the UK from 2030. Fractional distillation is used in oil refineries (Figure 5.41) to separate the complex mixture into fractions that contain similar boiling points and therefore similar molecular weights and properties. 1) They are a series of compounds with the general formula CnH2n+1. Most of the hydrocarbons in crude oil are hydrocarbons called alkanes. Hydrocarbons have different uses depending on their properties. Simply put - useless. Also, as all fossil fuels contain carbon, the burning of any fossil fuel will contribute to global warming due to the production of carbon dioxide.
