Chemical Engineering Degrees

What is chemical engineering?

Chemical engineering is 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

Undergraduate degrees

Entry requirements for undergraduate chemical engineering degrees typically include A-levels (or equivalent) in chemistry and mathematics, with physics or biology being advantageous subject. Some universities offer foundation courses for students who don’t meet the standard subject or grade requirements. International applicants may also need to provide English language proficiency scores (ex: IELTS, TOEFL) in addition to subject-specific qualifications.

If you hold a diploma or lower-level certificate in chemical engineering from a recognised institution, you may be eligible for direct entry into the second year of a degree programme. It’s best to check with individual universities to confirm available options.

Postgraduate degrees

A Master’s in Chemical Engineering or a Master of Science (MSc) degree in Advanced Chemical Engineering typically requires a bachelor’s degree in chemical engineering or a related field, such as chemistry or mechanical engineering. Some universities accept applicants from different academic backgrounds but may require preparatory coursework to build foundational knowledge.

Relevant industry experience can be beneficial or even mandatory for specialised programmes. International students must meet language proficiency requirements through tests like IELTS or TOEFL.

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 also offer a ‘sandwich year’, where students get to 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 an 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. 

For those looking to continue their studies further, postgraduate options available include Master of Science (MSc) degrees in Advanced Chemical Engineering or Masters in Chemical Engineering. These programmes offer opportunities to specialise in areas such as process engineering, energy systems, or biochemical engineering allowing students to develop advanced technical expertise and industry-relevant skills.

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. For those interested in pursuing advanced degrees, Master of Science (MSc) degrees in Advanced Chemical Engineering offer opportunities to deepen knowledge in these specialisations, including emerging fields such as green technologies and advanced materials.

Additionally, courses on engineering management, environmental impact, and safety and hazard engineering could even prepare students for diverse challenges in modern chemical engineering. For those interested in further specialising, a Masters in Chemical Engineering can focus on specific areas such as energy systems, biotechnology, or environmental engineering.
