The diagrams below shows how oil is expected in use of production of perfume.

The diagram illustrates how perfume is made from extracting oil.

Overall, it is discernible that the process consists of consecutive steps, commencing with heating water and ending with separating oil for perfume-making. It is also noticeable that the process is well-organized in three main stages including heating, mixing, and separating.

According to the diagram, the process begins with heating water in a special machine. When water boils and steam evaporates, aromatic plants are added. One of the subsequent steps that is important in making perfume is heating the mixture of water and aromatic plants until oil vapor is distilled.

As can also be seen in the diagram, the oil vapor is thinned out with cold water in a condensing machine before well-blending with essential oils. The process continues with separating essential oil in a separator in which hydrolat, commonly referred to as aromatic water is extracted and ready for making perfume and selling to customers

Certainly! Here’s an improved version of the original report:

The provided diagrams illustrate the sequential process involved in the production of perfume through the extraction of oil.

Overall, the process is clearly delineated in three distinct stages: heating, mixing, and separating, culminating in the extraction of oil specifically for perfume manufacturing.

The process initiates by heating water within a specialized apparatus. Subsequently, when the water reaches its boiling point and transforms into steam, aromatic plants are introduced into the heated water. An essential subsequent step in perfume production involves the continuous heating of the water-aromatic plant mixture until the vaporized oil is distilled.

The diagrams also depict the refinement of the oil vapor by its dilution with cold water in a condensing unit before its amalgamation with essential oils. This fusion continues by separating the essential oil in a dedicated separator, yielding hydrolat, known as aromatic water. This aromatic water is then readily available for perfume creation and subsequent distribution to consumers.

This revised version maintains the original data points while enhancing the vocabulary, refining the sentence structures, and ensuring clearer and more precise explanations.
