Making Crude Oil Useful: Fractional Distillation and Cracking One day, a giant was seen leaping (LPG) over a petrol/ gasoline station (petrol/ gasoline). Coal is mainly carbon but it may also contain sulfur compounds, which produce sulfur dioxide when the coal is burned. 9. know that alkanes and cycloalkanes are saturated hydrocarbons, 10. understand that alkane fuels are obtained from the fractional distillation, cracking and reforming of crude oil. does anyone have a good mneumonic to remember this? These write-on worksheets will ask learners to use their knowledge of crude oil in an applied context. The fractions of crude oil with the lowest boiling points and collected at the top of the column are LPG (liquid petroleum gas) and petrol/ gasoline. 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. Catherine is head of science at the Hinckley School, an 1118 academy in Leicestershire. Fractional distillation separates crude oil into fractions groups of hydrocarbon molecules with similar carbon chain lengths, properties and boiling points. What would you like to see from the Chemistry forum? [3] Fractional distillation allows a lot of useful products to be made from crude oil, with many environmental consequences for the use of those useful products! Hydrocarbons have different uses depending on their properties. Due to the different boiling points, crude oil can be separated into fractions (parts) by heating it in a process called fractional distillation. Shoot for 100%. Fractional Distillation - How Oil Refining Works | HowStuffWorks If a beaded fractionating column is used, sometimes a wad of glass wool is inserted into the top so that the beads do not spill out. The applications of this particular fossil fuel are far beyond that of mere electricity generation. How to remember fractions of crude oil? (AS Chem) In fact, we cannot meet this demand through the products of fractional distillation alone. There was such a blaze that the flames began to melt the tarmac (bitumen). This gas is a cause of acid rain. The jet couldnt be helped so a large diesel (diesel) truck had to drag it back to the airport, but there was a large oil (lubricating oil) spill on the way. Diesel 6. Fractions with different boiling points condense at different levels of the column and can be collected. For further information please see the related pages below: Figure 1. Other columns may be substituted. Students should be able to recall how boiling point, viscosity and flammability change with increasing molecular size. I am myanmar. Flashbang Science does not condone this sort of behaviour, in fact actively discourages it! Crude Oil Lesson 2 - Fractional Distillation - YouTube Legal. The steps of fractional distillation are as follows: You heat the mixture of two or more substances (liquids) with different boiling points to a high temperature. For alkynes only ethyne to be considered. Small molecules have very small forces of attraction between them and are easy to break by heating. Stewart has been an enthusiastic GCSE, IGCSE, A Level and IB teacher for more than 30 years in the UK as well as overseas, and has also been an examiner for IB and A Level. 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. Crude oil fractions come from fractional distillation. The process of fractional distillation is fairly simple, but is powerful in the way that it separates all the different, complex components of crude oil. Substances with high boiling points condense at the bottom and substances with lower boiling points condense on the way to the top. Depending on the length of the hydrocarbon we have different uses for each one. Once the temperature of the column falls below the boiling point of a hydrocarbon in the mixture, it is no longer hot enough for the hydrocarbon to stay in gaseous form. Each fraction contains hydrocarbon molecules with a similar number of carbon atoms and a similar range of boiling points. 5.3D: Step-by-Step Procedures for Fractional Distillation 5.7.1 Carbon compounds as fuels and feedstock, 5.7.1.1 Crude oil, hydrocarbons and alkanes, Most of the hydrocarbons in crude oil are hydrocarbons called alkanes. What is the process of distillation of crude oil? If you struggle to remember that, just think of CHristmas crackers (C for catalyst, H for heat). Due to the high number of intermolecular forces, the forces are more difficult to break in large molecules. The teacher versions (also editable) give answers to all questions. Heating is usually done with high pressure steam to temperatures of about 1112 degrees Fahrenheit / 600 degrees Celsius. Hydrocarbons have different uses depending on their properties.
