Amino acid salts (AAS) have emerged as promising alternatives due to their low toxicity, negligible vapour pressure, and superior thermal stability. Despite these advantages, their industrial deployment remains limited by increased viscosity following CO\u2082 absorption, reduced mass-transfer efficiency, and operational challenges associated with solvent foaming.<br>This project will develop and evaluate a novel foam-controlled amino acid salt solvent system comprising potassium sarcosinate (K-Sar), Aerosol OT (AOT), ethylene glycol (EG), and polydimethylsiloxane (PDMS). The research will investigate the interactions between viscosity reduction, gas\u2013liquid mass transfer enhancement, and foam suppression to improve CO\u2082 capture performance. By addressing key limitations of current AAS systems, the project aims to advance the development of a highly stable, reusable, and energy-efficient solvent platform for industrial carbon capture applications.<\/p>\n\n\n\n<p class=\"has-intro-font-size wp-block-paragraph\">Aim&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The primary aim of this project is to develop and optimise a foam-controlled amino acid salt solvent system for rapid and energy-efficient carbon dioxide capture from industrial flue gases. The research will investigate the synergistic effects of potassium sarcosinate, Aerosol OT, ethylene glycol, and polydimethylsiloxane on CO\u2082 absorption capacity, mass-transfer kinetics, viscosity management, foam control, and solvent recyclability. The goal is to establish a scalable and sustainable carbon capture platform that overcomes the operational limitations of conventional amino acid salt systems.<\/p>\n\n\n\n<p class=\"has-intro-font-size wp-block-paragraph\">Objectives&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>To quantify the exact kinetics of interfacial CO2 mass-transfer enhancement driven by low-dose AOT at the liquid-gas boundary layer.<\/li>\n\n\n\n<li>To optimise the mass capacity efficiency and fluid dynamics of K-Sar solutions by mapping the bulk thinning effects of Ethylene Glycol across deep carbon-loading thresholds.<\/li>\n\n\n\n<li>To characterise the physical bubble-rupturing mechanics and multi-cycle chemical stability of trace PDMS emulsions during low-temperature, catalyst-aided thermal regeneration (95\u00b0C\u2013115\u00b0C).<\/li>\n\n\n\n<li>To establish the long-term, multi-batch reusability index of the four-part formulation, ensuring zero chemical crossover, volatilisation, or structural degradation.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-intro-font-size wp-block-paragraph\">Significance&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Development of a High-Speed Carbon Solvent: Delivering an AAS formulation that matches or exceeds traditional MEA capture speeds while eliminating chemical evaporation losses.<\/li>\n\n\n\n<li>Elimination of the Scaling Trap: Providing an operational playbook for running non-precipitating amino acid networks that do not risk pipeline blockages or crystallisation.<\/li>\n\n\n\n<li>A Standard for Foam-Free Boiling: Proving that trace silicone emulsions can successfully suppress the heavy foaming risks of surfactant-mediated gas towers, making them safe for commercial deployment.<\/li>\n\n\n\n<li>Academic Publications: Submitting high-impact papers to leading peer-reviewed journals<\/li>\n<\/ul>\n\n\n\n<p class=\"has-intro-font-size wp-block-paragraph\">Ideal Candidate&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We are seeking a highly motivated PhD candidate with a background in Chemical Engineering, Chemistry, Environmental Engineering, Materials Science, or a related discipline.
