プロフィール概要

I am a chemical and process systems engineer specialising in the environmental and techno-economic assessment of emerging chemical, recycling, and circular technologies. I combine process engineering, life cycle assessment, and computational modelling to help R&D teams, technology developers, and engineering organisations determine whether a new process is environmentally credible, technically feasible, and economically viable before major scale-up and investment decisions are made. My expertise includes: • Aspen Plus process simulation and conceptual process design • automated Python-based modelling workflows • detailed mass and energy balances • process-specific life cycle inventory development • comparative and parametric life cycle assessment • techno-economic and scale-up assessment • sensitivity and Monte Carlo uncertainty analysis • environmental hotspot and break-even analysis • process-route and technology benchmarking • customised Python and Excel decision-support models • technical literature reviews and scientific reporting Rather than producing a single static environmental footprint, I develop transparent and adaptable assessment models that show how process yields, energy demand, raw materials, recovery systems, operating conditions, and scale-up assumptions influence environmental performance and economic viability. My research has focused particularly on the chemical and solvent-based recycling of polymers. As first author of a study published in Environmental Science & Technology, I developed an automated Python-Aspen Plus-LCA workflow to compare four chemical recycling routes for nylon 6 under changing process conditions and uncertain feedstock compositions. The work identified the technical conditions and process parameters that determine when different recycling routes become environmentally advantageous. I also led a techno-economic assessment of nylon-6 chemical recycling published in the Chemical Engineering Journal and contributed to research on ionic-liquid-based recycling, solvent-based polymer separation, and sustainable separation processes. I support clients in comparing alternative technologies, evaluating environmental and economic scale-up risks, identifying critical process improvements, and developing robust technical evidence for R&D, investment, and technology-development decisions. My objective is not simply to calculate environmental impacts. I identify the process parameters, technology choices, and scale-up conditions that determine whether a technology can succeed, and where development efforts can create the greatest environmental and economic value.

However, little is known about their relevant CO2 solubilities, CO2 mass transfer rates, and susceptibility to oxidative and thermal degradation under conditions relevant to DAC. We report here on the overall solubility of CO2 and CO2 mass transfer rates into a series of amino acid salts solutions. Additionally, the robustness of various amino acid salt solutions to thermal and oxidative degradation has been assessed. CO2 absorption rates into the amino acid salts solutions were observed to be in the same order of magnitude as aqueous monoethanolamine (MEA), with sarcosinate and lysinate solutions providing the fastest and slowest CO2 mass transfer rates at 25°C, respectively. Degradation data revealed that all amino acid salt solutions investigated in this study displayed elevated rates of thermal degradation at both 120 and 150°C relative to MEA. The opposite trend was observed with respect to oxidative degradation where all amino acid salt solutions showed a greater resistance to oxidative degradation than that observed for MEA under the conditions investigated here. Considering the degradation, CO2 absorption capacity, and CO2 mass transfer rate data, we propose the potassium salts of proline and sarcosine as the most promising amino acid salts (of those considered here) for further evaluation in DAC processes. Overall, this study provides valuable insight into the suitability of various amino acid salt solutions as absorption liquid for DAC. © 2024 The Author(s).
