Oil and Plastics: The Use of Fractional Distillation in Oil Refinery

(Ke E 10,11) Explain, using a diagram, the use of Fractional Distillation in an Oil Refinery. How is this method used to help produce chemico-technical products (fuels,solvents, etc).

Due to having different boiling points the substances in the crude oil can be separated if/by using fractional distillation. The crude oil is braked down and its steam condenses at different temperatures in the fractionating column. Every fraction contains hydrocarbon molecules with very similar numbers of carbon atoms.

(Ke C 10,11) Refineries often use cracking to produce chemicals from oil which can be useful precursors.

Explain why we have to “Crack” long-chain hydrocarbons instead of using the products of fractional distillation directly when we manufacture plastics
By cracking it will let us turn long chain molecules into shorter and more usable ones. It always makes short-chain composites, for example ethene and propene which have a double bond between carbon atoms. The double bonds make these composites reactivate, so they can be used as “New” plastics. If using the cracking method it will help us make/manufacture plastics, if we have a long chain molecule we will not be able to add other atoms, but by cracking the molecule it will break it down to small parts and it will help us to take the small/broken parts and add other atoms.

Describe in detail the production of a typical plastic like High density Polythene or PVC. from cracking to monomer and polymer.
To make PVC
