What is chemical engineering?
What is chemical engineering? It's the branch of engineering focused on designing, optimising, and operating processes that transform raw materials into valuable products through chemical, physical and biological changes.
Chemical engineers often work in two main areas:
Designing, manufacturing, and operating plants and machinery for large-scale industrial processes
Developing new or improved substances for a wide range of products
They blend principles from chemistry to create and refine products, considering economic viability, resource management, health and safety, sustainability, and environmental impact.
Entry requirements for chemical engineering degrees
Entry requirements for chemical engineering degrees usually emphasise a strong background in chemistry and mathematics, while knowledge of other sciences is beneficial. Some background knowledge of the nature of chemical engineering and its various real-world applications is also a good way to enhance your application.
Many institutions offer various entry routes into chemical engineering. You can enter from a natural sciences, engineering, or computer sciences background. Some institutions are even more flexible, accepting students from all disciplines. If you don't meet the required grades or subjects, foundation courses are available to help you acquire the necessary skills and knowledge.
Additionally, if you hold a diploma or a lower-level certificate in chemical engineering from a recognised institution, you might be eligible for direct entry into the second year of a degree programme. So, it’s advisable to check with the institutions you’re interested in to see if this option is available.
What to expect from chemical engineering degrees
Undergraduate chemical engineering degrees typically last three to five years, depending on the country, institution, and whether you are pursuing a Bachelor of Engineering (BEng) or Master of Engineering (MEng). The BEng usually takes three to four years, while the MEng lasts four to five years.
Some programmes allow BEng students to transfer to an MEng programme if they meet certain academic requirements, and MEng students may have the option to graduate with a BEng instead.
The MEng provides a deeper understanding of chemical engineering, more extensive project work, and can lead to Chartered Chemical Engineer status after gaining the necessary experience and qualifications.
Many institutions offer a ‘sandwich year’, where students work in the industry or study abroad. You can also combine chemical engineering with other disciplines like environmental engineering, business management, foreign languages, or humanities.
Whether you choose a BEng or MEng, you'll start with core courses in pure and applied mathematics, computing, CAD, and sciences. You’ll then proceed to study these topics in more depth and specialise by choosing from a range of elective courses.
In later years, you'll take advanced lab classes with industrial equipment and learn about the financial, ethical and environmental aspects of chemical engineering, with opportunities to study business, finance and management.
Teaching methods include lectures, tutorials, seminars, computer practice sessions, extensive lab work, and individual and group projects. Some institutions offer online classes, site visits (or field work), and industry professional-led sessions to provide insights into current practices and concerns in the industry.
Final assessment is typically a substantial research and development project, but you may also be tested through written examination, coursework, laboratory reports, multiple choice examinations, oral presentations and interviews.
Chemical engineering specialisations
Chemical engineering courses have expanded far beyond their origins in oil refining and petrochemical production, adapting to advancements in various fields. Today, students can explore a wide range of topics, from traditional subjects like fluid mechanics, mass and heat transfer, and thermodynamics to even cutting-edge areas such as nanotechnology, fuel cells, and bioengineering.
Courses typically include plant design, process systems, and process economics, as well as specialised subjects like biochemical engineering, membrane science, and sustainable engineering.
