Chemical Engineering: What Do You Really Study?
To transform chemical processes into large-scale production - from medicine and energy to food and materials.
What Do You Study in Chemical Engineering? Core Subjects, Year by Year
What do the degree courses cover?
Open a course to learn about its main topics and see what the work looks like in practice.
What do you learn in the course?Hadova for chemical engineering?
The course develops a mathematical language to describe continuous processes that change in time and space. Derivatives, integrals, functions in several variables and differential equations are studied and applied to flow, heating, reactions and optimization.
Main topics
- Derivatives, rates of change and approximations
- Integrals and incremental balances
- Functions in several variables and optimization
- Differential equations and models
What does it look like in practice?
For example, formulate an equation that describes the accumulation of material in a tank, solve for the change in concentration over time and check how the feed rate changes the settling time.
What do you learn in the course?General chemistry for engineering?
Build a quantitative understanding of the material structure, connections, reactions, energy and equilibrium - the basis for understanding raw materials and processes. The course teaches to translate a chemical formula into quantities, to predict the direction of a reaction and to understand how temperature, pressure and composition change a system.
Main topics
- The structure of the atom, bonds and intermolecular forces
- Stoichiometry and solutions
- Basic thermochemistry and kinetics
- Equilibrium, acid-base and electrochemistry
What does it look like in practice?
For example, calculate how much reagent is needed to achieve a given yield, identify the limiting reagent and estimate how a change in pH will affect the composition of the solution.
What do you learn in the course?Physics for Chemical Engineering?
You study the laws of mechanics, energy, electricity and waves that explain the operation of the equipment and the measurements in a process facility. The course connects forces and movement with pressure, pump rotation, heating, sensors and power consumption.
Main topics
- Forces, motion and rotation
- Work, energy and power
- Pressure, fluctuations and waves
- Electricity, fields and measuring instruments
What does it look like in practice?
For example, calculate the mechanical and electrical power needed for a pump that raises liquid between tanks and check where energy is lost in the system.
What do you learn in the course?Programming and engineering calculation?
The course teaches to use code as a tool for solving models, processing experimental data and automating engineering calculations. Decomposing a problem into functions, numerical methods, illustration, testing and maintaining a reproducible calculation process are practiced.
Main topics
- Variables, functions and data structures
- Numerical solution of equations and balances
- Data processing, analysis and presentation
- Testing, debugging and reproducing results
What does it look like in practice?
For example, you write a program that solves a material balance in hundreds of operating conditions, shows the conversion and consumption in a graph and alerts you to a non-physical result.
What do you learn in the course?Material and energy balances?
This is the core course that teaches to track all matter and energy that enters, exits, is created and accumulates in the process. Define system boundaries and degrees of freedom and solve stable or variable processes that include reaction, cycle, bypass and purification.
Main topics
- System boundaries, basis of calculation and degrees of freedom
- Mass balances for components and mixtures
- reaction, cycle, bypass and purge stream
- Energy balances, enthalpy and unsteady processes
What does it look like in practice?
For example, calculate flows and compositions in a plant where unreacted material is separated and returned to the reactor, and find how much heat must be supplied to maintain the temperature.
Frequently Asked Questions About Chemical Engineering
Is a degree in Chemical Engineering difficult?
There is no single answer — difficulty depends on your background, the institution, and your chosen study pace. According to this site's estimate, The degree is highly quantitative — mathematics and formal reasoning appear in nearly every course, and this is the part most students describe as challenging, and a large share of the reading material is in English. A good way to assess fit is to review the course map on this page: if most of the subjects interest you, the effort will usually feel worthwhile.
How long does a degree in Chemical Engineering take?
Usually 4 years (Engineering degree with laboratories, process design and project). Exact duration varies by institution and depends on course load and the track you choose.
Chemical Engineering or Civil Engineering — which is right for me?
The degrees most closely related to Chemical Engineering are Civil Engineering, Chemistry, and Architecture. Their differences are usually in emphasis rather than the overall subject, so the fastest way to decide is to compare their course maps — what you actually study in each program, year by year. You can also open the degree comparison tool to view the differences side by side.
