Question Types You’ll See
Imperial plans departmental interview days for Chemical Engineering selection, while exact 2027 details are not yet fully published. The interview focus recorded for this course includes motivation for Chemical Engineering, personal-statement discussion, mathematical, chemical and engineering reasoning, communication and suitability for a design- and process-focused course.
A strong approach is to prepare by explaining your reasoning aloud, especially when a prompt combines data, chemistry and estimation. The strongest answers usually show method: define the problem, state assumptions, calculate carefully, then reflect on limitations.
Sample prompt types recorded for the course include personal-statement discussion, motivation and course-fit prompts, unfamiliar applied chemical-engineering scenarios, graph or estimation tasks, and reflection on wider reading or project work.

Section 06
In practice, you should avoid building an application around one component. It helps to make the academic profile, ESAT preparation, personal statement and interview preparation all point to the same thing: serious readiness for quantitative chemical engineering.
Our recommendation · weighting of admission factors
Oxbridge Mentors recommendation, drawn from observed offer patterns. Imperial College London does not publish official weightings — exact balance varies by college, course and year.
Section 07
The academic centre of this course is Mathematics and Chemistry, and the ESAT modules are Mathematics 1, Mathematics 2 and Chemistry. Use the personal statement to show why you want chemical engineering rather than just chemistry, mechanical engineering or environmental science.
A strong approach is to write about processes. A strong paragraph might take one example, ammonia synthesis, carbon capture, battery materials, pharmaceuticals, water treatment or hydrogen, and explain the mass balance, energy demand, separation problem, safety issue or trade-off that interested you.
Avoid listing books, channels and competitions without reflection. One well-explained project, calculation or case study usually says more than five names dropped into a paragraph.

Chemical Engineering PS Example →Section 08
Projects are useful because they force you to think like a process engineer: define a system boundary, make assumptions, calculate, test the result, and explain what is missing. You do not need expensive equipment; a transparent spreadsheet model can be stronger than a polished but unexplained outcome.
Section 08
Other supercurricular work should support the same core profile: quantitative chemistry, engineering judgement, process safety and industrial context. Keep evidence of what you actually did, not just what you consumed.
These activities are support, not substitute. They work best when they sharpen your reasoning for the course itself.
Process-calculation notebook:
Keep a notebook of mass balances, energy balances, reaction-rate calculations and dimensional-analysis problems. Admissions readers value evidence of quantitative thinking beyond memorised chemistry.
Industrial case studies:
Read about ammonia, water treatment, battery materials, carbon capture, polymers or pharmaceuticals, then explain the process steps and constraints in your own words.
Safety and ethics:
Study well-documented process-safety incidents and identify how design, control systems, human factors and regulation interact. Avoid sensationalism; focus on engineering lessons.
Simulation and data:
Use spreadsheets, Python or accessible process simulators to test assumptions. Simple, transparent models are more useful for admissions than unexplained black-box outputs.
Chemistry, maths and physics problem solving:
Practise challenging quantitative problems in physical chemistry, mechanics, thermodynamics and calculus. Chemical Engineering at Imperial is strongly mathematical.
Reflective reading:
Read one introductory chemical-engineering text and one broader sustainability or industrial systems text, then connect them to a specific process or problem in the personal statement.
Section 08
Competitions are not required. What they do well is stretch problem solving, accuracy under pressure and the habit of explaining unfamiliar science carefully.
None are required; one or two done well beats five half-attempted.
Section 09
Year
01 / 04
1
Core science, mathematics and process fundamentals
The first year builds the common technical base for the MEng. Students cover mathematics, chemistry, thermodynamics, transfer processes, separations and process analysis, while Chemical Engineering Practice introduces practical engineering work and the department's mastery approach.
Year
02 / 04
2
Reaction, separation, control and applied mathematics
The second year deepens the engineering core and moves from foundational calculations to more practical engineering problems. Students study transfer processes, reaction engineering, thermodynamics, process dynamics and control, separations, chemistry and engineering mathematics, alongside Chemical Engineering Practice 2.
Year
03 / 04
3
Process design with one specialist option
The third year brings together reaction engineering, particle engineering, process design, process optimisation, safety and environmental engineering. Students also take I-Explore and choose one specialist option, allowing them to begin tailoring the degree towards areas such as nuclear, biochemical, energy, heat-transfer or fluid-mechanics themes.
Year
04 / 04
4
Advanced practice, research and six options
The final year reaches Master's level. Students take Chemical Engineering Practice 4, described by Imperial as using innovative thinking to develop new process strategies, technology and analytical ability through a research project, and choose six advanced optional modules.
Section 10
For a first pass, Chemical Engineering Explained: Basic Concepts for Novices is useful because it introduces core ideas without assuming full undergraduate knowledge. For applicants who want more depth, Elements of Chemical Reaction Engineering shows how kinetics becomes reactor design, while Transport Phenomena connects momentum, heat and mass transfer. Sustainable Energy - without the hot air is also useful for applicants interested in energy systems because it forces quantitative thinking about trade-offs rather than slogans.
For video learning, LearnChemE gives short chemical-engineering screencasts and simulations, while AIChE Academy shows the breadth of professional chemical engineering. Chemical Engineering Guy is useful for early explanations of process equipment and thermodynamics, and AIChE ChEnected is stronger for career context and industrial applications.
For structured study, Chemical Engineering Thermodynamics from MIT OpenCourseWare And Transport Processes introduce the mathematical style of the discipline. For professional context, Doing a World of Good and Process Safety with Trish & Traci are useful because they connect engineering decisions to energy, health, safety and practical risk.
Section 11
Imperial's 2023 undergraduate Chemical Engineering graduate-outcomes table records employment across professional, scientific and technical services, mining and quarrying, manufacturing, financial and insurance activities, information and communications, and other recorded sectors. The useful point for applicants is not that every graduate becomes a plant engineer. Chemical Engineering can lead into process industries, scientific and technical services, energy, manufacturing, finance, data-facing roles and further study, so your application should show both technical depth and judgement about real systems.
Section 12
Because Mathematics and Chemistry are required, applicants whose schools have limited subject availability should make the available context clear through school evidence rather than relying on the personal statement alone. Contextual eligibility and policies are reviewed by Imperial, so the live 2026-27 contextual admissions page International applicants should not assume UK contextual flags apply automatically; country-specific qualification context should be handled through international admissions guidance and the UCAS reference.
