The diagrams below shows how oil is expected in use of production of perfume. Summarize the information by selecting and reporting the main features and make comparisons where relevant. You should write at least 150 words.

The diagram illustrates the technique of producing perfume from

oil

.

Overall

, there are four main stages, starting from the boiling of the input

water

and ending with the culmination of the refined hydrolat. In the first stage of the process,

water

is heated by

inside an airtight container until it transforms into steam. After that, it will be transferred to the second container through a tube. At

this

step, hot air is used to increase the temperature of aromatic plants, letting the raw materials produce

oil

and

then

collecting the mixture of steam and

oil

vapour within. In the next stage of the progress, the vaporized

oil

is transported to a condenser where

this

product is condensed by a spring-shaped tube. At the same time, both hot and cold

water

supplied from two different tubes are used to support

this

condensing procedure. In the

last

step,

water

mixed with essential

oil

will be transported to a large separator that filters the

oil

.

Then

the hydrolat, known as aromatic

water

, is ready to be used for different purposes, catering for consumers’ needs.
