Try again, If you got 2 correct answers: 2/4 - lukewarm, but not great, If you got 3 correct answers: 3/4 - things are hotting up! The general formula for the homologous series of alkanes is CH, 5.7.1.2 Fractional distillation and petrochemicals, 5.1 Atomic structure and the periodic table, 5.1.1 A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes. New cars and vans powered wholly by petrol and diesel will not be sold in the UK from 2030. Reply 1. Heating is usually done with high pressure steam to temperatures of about 1112 degrees Fahrenheit / 600 degrees Celsius. Many of the fuels on which we depend for our modern lifestyle, such as petrol, diesel oil, kerosene, heavy fuel oil and liquefied petroleum gases, are produced from crude oil. Rhys Baker (author) from Peterborough, UK on May 31, 2012: Woops! C3.4 Why is crude oil important as a source of new materials? Fractional distillation is the most common form of separation technology used in petroleum refineries, petrochemical and chemical plants, natural gas processing and cryogenic air separation plants. This website collects cookies to deliver a better user experience. Students should be able to explain how fractional distillation works in terms of evaporation and condensation. Jet fuel (kerosene) 5. The hot gases rise up the column. Due to the different boiling points, crude oil can be separated into fractions (parts) by heating it in a process called fractional distillation. One day, a giant was seen leaping (LPG) over a petrol/ gasoline station (petrol/ gasoline). So l learned refinery that l got knowledge very very thank you. WS.3.5 Interpreting observations and other data (presented in verbal, diagrammatic, graphical, symbolic or numerical form), including identifying patterns and trends, making inferences and drawing conclusions. The many hydrocarbons in crude oil may be separated into fractions, each of which contains molecules with a similar number of carbon atoms, by fractional distillation.
