Band 7+: The diagram below shows how oil is expected in use of production of perfume Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The process demonstrates the extraction of oil in perfurme manufacturing.

There are four stages in the diagram, beginning with the evaporation of water, followed by the collection and condensation of essential oil. Lastly, the condensed oil is poured into water.

Intially, water is boiled to create hot stream which is then used to extract the oil in plant crude matter. In the first step, water is introduced to the boiling chamber before being evaporated by the high heat of the mentioned chamber. In the following step, the generated steam is conveyed into a machine containing plants, then, the temperature of the steam will strip the plants of their essential oil.

For the remaining steps, the oil is converted to the liquid state and finally mixed with water to create perfume. At the third stage of the process, vaporized oil is transported to the final chamber, the low temperature of which will trigger the condensation process of essential oil. Finally, the condensed oil blend with water to create perfume.
