This page lists over 150 topics suited to design, simulation and laboratory projects.
We all know that writing a chemical engineering dissertation is a challenging, burdensome, and hefty task because this branch of engineering encompasses a vast array of knowledge from different science subjects such as biology, chemistry, and physics.
Choosing an appropriate and suitable topic for your chemical engineering dissertation can turn out to be tricky since this subject involves several subtopics spanning from the application of thermodynamics to product purification techniques used in various industries, such as the pharmaceutical industry and food industry.
As a result, it becomes challenging to put forward a chemical engineering dissertation that meets the required quality standard and scores the desired marks.
To help you get started with brainstorming for chemical engineering topic ideas, we have developed a list of the latest topics that can be used for writing your chemical engineering dissertation.

Topic 6: Methane Pyrolysis Versus Steam Methane Reforming with Carbon Capture: A Process Simulation and Cost Comparison for Low-Carbon Hydrogen

Frequently Asked Questions
Start from a process problem rather than a broad technology: an energy-hungry separation, a reaction that is hard to scale up, or a waste stream that could become a product. Then check which tools you can use, such as a laboratory rig, a process simulator or published plant data.
Your supervisor’s research group, industrial placement experience and journal articles in the field are good sources of ideas.
Popular themes include low-carbon hydrogen and ammonia, carbon capture and utilisation, energy-efficient separations, process electrification, continuous pharmaceutical manufacturing and chemical recycling of plastics.
Process safety, digital tools such as soft sensors and machine learning, and bioprocessing for food and medicines are also strong areas for dissertations and theses.
Accredited UK chemical engineering degrees include substantial design work, usually a team project to design a complete process plant. Many also include an individual research project, which universities may call a dissertation or thesis. In the US, a master’s research report is usually called a thesis.
Check your programme handbook, because expected length, methods and assessment differ.
Yes, many projects are based entirely on modelling. Process simulators such as Aspen Plus and Aspen HYSYS, available through many universities, and the free DWSIM simulator support flowsheet and design studies, while Python, MATLAB or OpenFOAM suit kinetic, control and fluid flow models.
Validate your model against published experimental or plant data so that your conclusions are credible.
A good seminar topic explains one technology and its trade-offs clearly, such as methane pyrolysis, dividing wall columns or single-use bioreactors. A good project topic goes further: it sets a research question and answers it through experiments, simulation or data analysis.
Pick a topic with enough published sources for your literature review and a method you can complete in the time available.
Yes. Complete the free topic form at the end of this page, or on our free dissertation topics page, and a subject specialist will send you a custom topic with an aim and justification.
