How are products from oil obtained and used? Oil. What actually is oil? Oil is or was originally made of organic material, like plankton. When the plankton dies it sinks to the sea floor. Over time it becomes part of the many layers of sedimentary rock that form there. Lots and lots of layers build up putting pressure on the lower layers, turning them into petroleum. If there is enough heat and pressure it will turn into crude oil. Crude oil is made up of different carbon-based fractions. These can be extracted using a fractionising column. All these fractions have different boiling points, this means that when heated, certain parts of the crude oil will evaporate and can therefore be collected by condensing it. This means that if you know the certain boiling points of each fraction you can separate the certain fraction you need, which is used for different products. This...
