Advanced Chemical Engineering MSc postgraduate personal statement example

Personal statement example

On my first week of night shifts at a chilled desserts factory, I was shown how to start the cleaning-in-place cycle on the pasteuriser. Caustic wash, rinse, acid wash, rinse: the sequence ran from a fixed timer whatever had gone through the line that day. One night I watched the conductivity reading on the final rinse drop to near water level several minutes before the timer finished, and the extra water simply ran to drain. When I raised it, my shift lead explained that the timings were set conservatively after a hygiene failure years earlier, and nobody wanted to be the person who shortened them. That conversation captured something I want to understand properly: how engineering decisions in real plants are balanced between efficiency, safety and the confidence of the people who run them. I am applying for postgraduate study in advanced chemical engineering to build the technical depth to work on those trade-offs with evidence rather than instinct.

My BEng gave me a solid grounding in transport phenomena, reaction engineering and separation processes, and I most enjoyed modules where a model had to meet messy data. My individual final-year project examined fouling from heated milk on stainless steel coupons. Using a small heated cell in the teaching laboratory, I compared deposit mass at three surface temperatures and two flow rates, then tried to relate the results to the simple rate expressions I found in the fouling literature. The trends were clear at higher temperatures, but scatter at the lowest temperature meant I could only report that the effect was small within my method's resolution. Learning to say exactly what my data could and could not support was one of the most useful things the project taught me.

In our group design project, a plant recovering solvent from a pharmaceutical waste stream, I was responsible for heat integration. I built composite curves, applied pinch analysis to identify a minimum utility target, and then argued with my group about which exchanger matches were worth the added complexity. We agreed on a network that recovered most of the available heat with fewer units than the theoretical optimum, and I wrote the section justifying that choice. I would now like to study process systems and optimisation more rigorously, alongside sustainable process design, so that compromises like ours rest on proper costing and modelling.

The factory job, which I took after graduating while deciding on further study, has been valuable in a different way. As a process operative I set up batches, logged temperatures, cleared blockages in filling heads and completed hygiene records that auditors actually read. I learned that a well-designed procedure is one people can follow at four in the morning. With my lead's encouragement, I collected conductivity data from several weeks of rinses and summarised it in a short note for the site's technical team. They have not changed the timings, and I understand why validation must come first, but they kept the note for a planned review.

Outside work I swim in a local lake from spring to autumn and help on Saturday mornings at a junior swimming club, mostly managing lane groups and keeping young swimmers warm and listening. It is unrelated to engineering, but it has made me patient at explaining things clearly and calmly.

I am drawn to roles in process improvement within food, pharmaceutical or water industries, where reducing energy, water and chemical use depends on understanding both the science and the plant. Postgraduate study would let me deepen my modelling, simulation and design skills, and take on a substantial research project with more independence than my undergraduate work allowed. I bring careful laboratory habits, practical experience of how processes run day to day, and a genuine willingness to question a fixed timer, politely, with data.
