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. The Student Room and The Uni Guide are trading names of The Student Room Group Ltd. Register Number: 04666380 (England and Wales), VAT No. But how does this work? Within the fractionating column, crude oil is split into the following fractions: Below is a story to help you remember the order of these fractions. 4.7.1 Carbon compounds as fuels and feedstock. Before using the column, remove this wad as it may interfere with the passage of vapors (Figure 5.44a). As you can see in the video opposite, cracking needs a catalyst and a high temperature. This website collects cookies to deliver a better user experience. Crude oil must first be desalted, by heating to a temperature of 100-150 C and mixing with 4-10% fresh water to dilute the salt. Heating is usually done with high pressure steam to temperatures of about 1112 degrees Fahrenheit / 600 degrees Celsius. 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. Distillation can be used to remove the monomer as it forms. 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. LPG and 2. Test Yourself What are the most competative courses at Cardiff university? The fractional distillation process starts by heating up the material to over 400 degrees Celsius in order to vaporize it. Production of refinery gas, light gasoline, naphtha, kerosene, gas oil and residue fractions. Crude oil is a mixture of many different compounds. The separation of various components of crude oil is one of the very common examples of fractional distillation in the industry. Intermolecular forces acting between molecules are known as van der Waals forces. Fortunately, we have much more of the larger fractions than are needed. In general, shorter chain hydrocarbons are more useful than longer chains. Legal.
