I’ve decided to study Industrial Engineering, and there are two main reasons that helped  me select it as my major. First of all, there are various fields and topics that industrial engineers are involved with. Comparing to other disciplines, industrial engineering gives you way more options of fields to work in. This really was appealing to me when I had to choose my discipline. I knew I wanted to become an engineer, but I wasn’t sure what exactly I wanted to do as an engineer.  So the fact that industrial engineering has various fields of study grabbed my attention and helped me make a decision. It also leads to my second reason. Various fields and topics mean that there are obviously many different job opportunities. When I heard that industrial engineers can be hired in many different types of companies, factories, and even hospitals, I could actually picture my future vividly. I really like the perfume industry, and I honestly wanted to become a professional perfumer. So, I had to choose either an engineer or a perfumer. However, I realized that I can also work as an industrial engineer in the perfume industry. So, what I really want to accomplish is I want to be hired in perfume companies as an industrial engineer, and do stuff that industrial engineers do such as data analysis, process developing, or supply chain management.

Part 2

Perfume is one of the chemical products that is being used in our daily lives. Currently, the process being used isn’t that complicated. First of all, raw materials such as flowers, fruit, grasses, and animal secretions, etc, have to be collected. Then, the materials pass through the collection process where plants get harvested, fatty substances from animal products get extracted, and aromatic chemicals get created in the laboratory. Then, they pass through the extraction process. In this process, oils are extracted from the plants by several methods: steam distillation, solvent extraction, enfleurage, maceration, and expression. In steam distillation, steam is passed through plants, turning the essential oils into the gas which eventually gets cooled and liquified. Under solvent extraction, a petroleum ether is poured over the flowers in a large rotating tanks. It extracts the essential oils, and the flower parts are then placed into the ethyl alcohol which gets burned off by the heat, leaving a perfume oil on the bottom. During enfleurage, grease is being used to absorb flowers’ fragrance. Maceration is similar to enfleurage, it uses warmed fats instead of grease. Expression is one of the oldest method, and by this method, fruits or plants are pressed until all the oil is squeezed out. Once the oils are collected by these methods, they get blended together by a master in the field, known as a “nose.” A scent gets created, and it gets mixed with alcohol. The amount of alcohol can vary. Last but not least, perfume passes through the aging process. After aging several months and years, the perfume will be tested by a “nose,” and gets ready to be sold.
