Chemical Engineering for Energy and Environment postgraduate personal statement example

Personal statement example

At six each morning, before the first tunnel washer starts, I read the gas meter at the commercial laundry where I work. The figure goes into a spreadsheet next to that day's tonnage of hotel linen, and over eighteen months those two columns have taught me more about energy than I expected from a job I took to pay rent after graduating. I want to pursue postgraduate study in chemical engineering for energy and environment because I would like to move from noticing where energy goes in a process to designing ways to keep it.

My undergraduate degree in chemical engineering gave me a solid grounding in thermodynamics, transport phenomena and reactor design, and I achieved a 2:1. The part I valued most was my final-year research project, which studied carbon dioxide absorption into aqueous monoethanolamine in a small packed column in our teaching laboratory. Working with a partner, I varied the liquid flow rate and amine concentration, measured outlet CO2 with an infrared analyser and estimated overall mass transfer coefficients. Our results were modest and the column was far from industrial scale, but I learned how much patience accurate data needs: recalibrating the analyser, waiting for steady state and rerunning tests when a leaking fitting distorted a morning's readings. The project also made the central difficulty of amine capture concrete. Absorbing CO2 is relatively easy; regenerating the solvent takes a great deal of heat. I finished the report wanting to understand that energy penalty properly, and the alternative solvents and process configurations being explored to reduce it.

The laundry has kept that question alive in an unexpected way. My role is shift supervisor, which mainly means organising a team of six, keeping machines loaded and dealing with jammed ironers. Because I had an engineering degree, the operations manager asked me to help with the monthly utility figures. I noticed that gas use per kilogram of linen rose noticeably whenever we ran small, mixed batches, since the boiler and dryers were cycling inefficiently. I suggested scheduling batches by fabric type to keep loads fuller, and we trialled it for a month. The improvement was real but small, and I was careful in presenting it because weather and order volumes also changed. What struck me more was the warm wastewater leaving the building every hour. I read about heat exchangers for laundry effluent and produced a rough estimate of recoverable heat for the manager. It is not my decision whether to invest, but working through the numbers showed me how far my undergraduate knowledge could take me and where it stopped, particularly on fouling and cost.

Outside work, I am treasurer of my local allotment association. It is unglamorous: collecting rents, keeping accounts and applying for a small council grant for a shared water butt system. It has made me comfortable explaining figures to people with no interest in spreadsheets, which I expect to matter in any engineering career. I also swim in a nearby reservoir from spring to autumn, and I enjoy it as a break from engineering rather than as an extension of it.

At postgraduate level I hope to deepen my understanding of separation processes, process integration and heat recovery, and to develop stronger skills in process modelling, which my degree introduced but did not explore in depth. I am especially interested in how carbon capture and industrial energy efficiency can be assessed together rather than separately, since both come down to what a plant does with its heat. I bring reliable laboratory practice, eighteen months of responsibility in a working industrial environment and a habit of checking my own conclusions. I would like to use advanced study to turn those into the expertise needed to work on decarbonising process industry.
