Why I Became a Chemical Engineer

Guest Blogger: Scott Mobley, Intern, Invensys Operations Management

At the bright age of 18, I had landed in my last year of High School and with the support of my parents, was about to apply for college.

But despite all those years of schooling, I hadn’t quite made up my mind of what direction my life would take. At an early age I had been fascinated by the world, coming up with little “experiments” of which were not more sophisticated than sticking various items in the freezer and seeing what happened to them. Yet until that senior year with college applications in hand, I had not given a moment to considering a college major. Harkening back to my young inquisitive mind, the sciences had been preferable classes. That senior year blessed me with a wonderful chemistry course, challenging and thorough. The instructor’s personality was also cheerful and made the course enjoyable.
Chemistry was my future, I resolved, and began filling it out as my desired major on the applications. But wait; there was another major with ‘Chem’ in the title ‘Chemical Engineering’.  I knew nothing about it. Searching the web, I gathered some information.
  • A challenging major
  • Grapples with a vast scope of subjects from physics to biology to materials science.
  • Applies knowledge to solve industrial issues, such as improving yields, and environmental protection.
The potential difficulty caused a pause, but its engineering title and description was also intriguing. I pondered some more, feeling that this major, if it turned out not to be right for me, could always be converted to pure chemistry. I decided to go for it.
Fast-forward to college. Admitted as a chemical engineering major to the University of California, Irvine, freshman year was a refresher of many high school subjects, with a tighter focus on chemistry and math. So far, so good.
It wasn’t until the second year at UCI did the first chemical engineering specific course appear. That first day all the bright-eyed chemical engineering majors in the room took their seats as the professor began a lecture about buying a hat. Buying a hat? This was no ordinary hat though, this hat was bought with a fraudulent $100 check and now the bank wants its money back from the store owner. The question is, how much did the store owner lose?
The example didn’t just apply to hats, this was beginning mass transfer. Where is the hat?  The criminal has it. How much money was lost? The store owner lost both the material good, the costs for him to purchase or make it, and he has to pay money the bank back. This problem and others, dealing with such subjects as a washer removing dirt from clothes, and drying wood in a furnace, opened my eyes. Chemical engineering didn’t have to be only about chemistry, it could be used for anything. The information gained through the courses focused on some specific topics, but the approach to these problems was applicable anywhere. Modeling flows of people through a park or enhancing one’s cooking, a chemical engineer could tackle the problem. At its heart, this is what I really enjoyed about the major.
While I tried my hand with a lot of different subjects at college, from video game development to counter-terrorism, I found that being a chemical engineer best exemplified my passion to create and come up with creative solutions to problems. The flexibility of the degree also allows exploration into many fields both in and out of college. So if you are looking for a major, and you enjoy quantitatively describing the world, perhaps becoming a chemical engineer is a wise choice for you.


**Side note**
Scott is currently working for us for the next month or so and is doing a fantastic job. He is extremely creative and I will be sad to see him go. He has his degree in Chemical Engineering and would be an asset to your company.

University Partner Program at Invensys

I think that promoting the software tools that professionals use in the workplace among the colleges and universities that are teaching our future workforce is important. In order to be successful professionals, students should prepare in school on the same tools that they will be using as professionals. A lot of companies do a great job of promoting their professional tools within academic instiuitions, and Invensys Operations Management is no exception. The SimSci-Esscor and Wonderware brands have the University Partner Program that aims to leverage the global academic brain trust to advance the engineering professions. Unfortunately, the program has been without a leader for sometime, and despite everyone's passion for helping academic institutions, we have fallen down on the job.

However, there is hope! We currently are looking for an Academic Program Manager at Invensys to help guide the program and extend its reach in academia. If you think you can help us in promoting our University Partner Program, please view the job description and apply here!

Depressuring Unit in PRO/II

PRO/II

The Depressuring Unit simulates the time-pressure-temperature relationships which occur when a vessel is depressured through a relief or control valve. The initial phase of the vessel contents may be either a vapor or a vapor-liquid mixture. Several different valve flow models and vessel configurations are available. Several heat input models are also available to simulate the pressuring of the vessel by a fire or other means. An optional external makeup stream may also be specified.
  1. Place a Depressuring Unit from Batch Tab and connect it with a feed and vapor stream
  2. Enter the Initial and Final Depressuring conditions which can be either based on time or pressure
  3. Enter the Calculation options which could be as shown in the figure or can even be left as default values
  4. Enter the Valve data. In this example, the Valve model is based on Supersonic Flow. Please refer to Help for further information about Valve constant – C
  5. Provide the vessel data. There are four options and the final one being Unspecified shape where the user can just enter the Vessel volume

Why I Decided to Become a Chemical Engineer


My Path to Chemical Engineering

As I assume most engineers were, I was always best at math and science in school. Those were the courses that always interested me the most and I excelled in them. Up until high school, any science classes I had were just general courses. We learned about clouds and weather, different animals, volcanoes, earthquakes, the planets, and even the basics of hydraulics. I enjoyed these subjects very much and it was fun to actually do something in class, like an experiment, instead of just reading books.

I had mixed feelings about chemistry coming out of high school though I still enjoyed science and math so I knew that I wanted to be an engineer of some sort. I wanted to learn about calculating and predicting things that could be observed; I just did not know what field I wanted to enter. I could not make up my mind and I applied to many schools as “undeclared engineering.”

Probably the most defining moment for my decision making process was when I attended an engineering open house at the University of Connecticut. Each engineering discipline had a poster and a little setup that outlined what fields they encompassed and what you could do with that specific degree. I looked around at all of the displays and I noticed that the poster for Chemical Engineering seemed to be a conglomeration of the other engineering posters. It looked to me like the Chemical Engineers had taken pictures from the other majors and pasted them onto their own poster board. Interested, I approached the table and asked why their poster was apparently a combination of the others. The response that I was given was that Chemical Engineering had “its fingers in many pies” and with a degree in the field you could go in a great deal of different directions. These directions included pharmaceuticals, oil, materials, foods, chemicals, alternative fuels, nanotechnology, and more.

The idea of having a degree that could open such a wide variety of career options stuck with me and I decided that I wanted a degree that could give me the widest array of career paths. I also heard that Chemical Engineering was one of the most difficult majors and I thought it would be a good challenge and a degree that I could be really proud of. I was still not sure if I would stick with Chemical Engineering, but I at least had a starting point.

I visited Villanova, the school I now attend, and I went to a presentation on Chemical Engineering. The head of the Chemical Engineering department gave the presentation and he went over all of the exciting fields that Chemical Engineers were a part of. The list mentioned everything I went over previously but he gave a more exciting, visual presentation with demonstrations of glassy metals and descriptions of nanotechnologies based on nature. I was extremely impressed and decided that Chemical Engineering was the major for me and Villanova was where I wanted to learn it.

I still have a career path to choose and, because of my choice to keep as many doors open as possible, this choice will be a tough one. I am hopeful that I will find my true calling eventually, and I am sure it is within the realm of the vast Chemical Engineering umbrella.
