Chemical Engineering

Chemical engineers have a huge impact on many products we use every day, because chemicals are involved in many products. Chemical engineers around the world design and manage the processes and equipment for large-scale manufacturing of all sorts of chemicals used in many products. They also work in a variety of manufacturing industries other than direct chemical manufacturing, such as those producing medicines, energy, electronics, food, clothing, and paper.

Chemical engineers rely on their knowledge of mathematics and science, particularly chemistry, to overcome technical problems safely and economically. And, of course, they draw upon and apply their engineering knowledge to solve any technical challenges they encounter. There are challenges that arise in the production of chemical and these are solved by Chemical engineers.

What makes it unique?

Chemical engineers blend skills in a range of areas, including chemistry, biology, physics, and math to solve problems that involve the production or use of chemicals, fuel, drugs, food, and many other products. They have to have experience in a range of areas to get the job done!

Problem solving is a key task for a Chemical engineer. In addition to working out processes to ensure safe and efficient chemical manufacturing, their expertise is also applied in the areas of law, education, publishing, finance, and medicine, as well as many other fields that require technical insights.

Their daily work is often impacted by the area they specialized in. Some may specialize in a particular chemical process, such as oxidation or polymerization. Others specialize in a particular field, such as nanomaterials, or in the development of specific products. But they must be aware of all aspects of chemical manufacturing and how the manufacturing process affects the environment and the safety of workers and consumers.

In the course of a day they may have to jump between several different projects, or advise clients or others on a range of topics. Multitasking is part of the job of a Chemical engineer!

Safe Water for Drinking:

According to survey of chemical engineers, clean drinking water ranked at the top of the chemical engineering inventions that had impacted the world. For some, access to safe water is taken for granted, but all over the world many people struggle with access to safe water. Most of the water available to us is salt water. Desalinization is a process through which salt and minerals are removed from salt water to create a fresh water supply, just one example of how chemical engineers work to provide safe water.

There are also legal limits which vary in different countries regarding how many contaminants are acceptable in drinking water.  Chemical engineers work to solve problems related to removal of contaminants to meet standards. The World Health Organization provides many facts on the challenges of providing safe drinking water around the world. Recognizing the growing challenge of water scarcity the UN General Assembly recently launched the Water Action Decade, to mobilize action that will help transform how we manage water.

Take a tour via the video to the right of the purification process used at the Iowa City Water Plant to see how 5.6 million gallons of clean, safe drinking water are produced each day!

More details:

Chemical engineers work in manufacturing, pharmaceuticals, healthcare, design and construction, pulp and paper, petrochemicals, food processing, specialty chemicals, polymers, biotechnology, and environmental health and safety industries, among others.

They also contribute to the development of the following products: agricultural chemicals, industrial gases, paints, pigments and inks, as well as soaps, detergents, perfumes, and cosmetics. Even synthetic fibers, other textiles and films require the support of chemical engineers!

With so many applications, chemical engineers are employed all around the world by many companies. Just a few examples of larger firms are listed below but you can find chemical engineers employed in every major city!

For most engineering careers:

  • a bachelor’s degree is required
  • a master’s degree may be recommended for those specializing or interested in management
  • students may also start with a related associate degree and then move on to a bachelor’s when they have settled on a degree path.
  • many students are required to participate in a co-op program while at university to gain real world experience in their chosen field.
  • education doesn’t really stop…engineers need to stay current as technology changes and materials and processes improve over time.
  • many professional societies offer certificates and coursework to support continuing education for their members.

For chemical engineering specifically, and despite its name, a chemical engineering education includes not just chemistry, but also biology, physics, and mathematics. IChemE offers a Student pocketbook PDF with concepts, principles and formulae for chemical engineering students.

It is important to select an engineering degree that has been accredited to meet basic standards.  Find out more and browse TryEngineering’s global database of accredited engineering and computing programs.

Providing medications to patients in exact doses that can be relied on to be consistent is one of the greatest contributions of chemical engineering. While a chemist would invent a new drug, it is the chemical engineer who develops and oversees the manufacturing process to ensure that millions of pills all contain exactly the same dose throughout production. They are also responsible for ensuring the product safety and purity, as well as considering the cost and time efficiency of the process to ensure profit margins. They have to do all this while adhering to industry regulations and also having a plan for disposing of waste products. In the end, it means that safe drugs can be efficiently made to help people all over the world with their health needs.

In the pharmaceutical industry, chemical engineers might work at various stages of production including, device development, research and development, testing and quality control, manufacturing, project management and system design.

Did you know you can explore chemical engineering in your community? Investigate how water arrives at your home kitchen sink.

  • Does it come from an underground well or does your town provide water through a piping system?
  • What sort of testing does the water undergo to ensure it is safe to drink? Is this a task done by the town you live in, or do you test your own water?
  • What systems are in place locally to treat water if it does not meet standards?
  • Do you think standards are the same in every town, every country?
  • If you were camping, and the water source was a local stream, would it be safe to drink? How would you know?
  • How do you think chemical engineering has played a role to help ensure that safe drinking water is available around the world?
