We are seeking a motivated postdoctoral researcher to contribute to the development and optimisation of technologies for recovering valuable elements from high-salinity brines, with produced water from offshore oil and gas production as an initial focus.
You will join an international research environment and collaborate with researchers across DTU and with industrial partners on projects combining experimental investigations, chemical analysis, thermodynamic modelling and process engineering.
Your overall focus will be to advance the development of efficient and environmentally sustainable methods for recovering critical raw materials from complex aqueous streams. You will investigate chemical separation and precipitation processes, evaluate their performance through laboratory experiments and modelling, and contribute to the development of integrated workflows for process optimisation and technological scale-up.
The research will involve high-salinity brines containing valuable elements such as lithium, magnesium, boron, silicon and rubidium. Particular emphasis will be placed on understanding the influence of water composition, chemical conditions and process parameters on recovery efficiency, product purity and operational performance.
Working closely with colleagues at DTU Offshore, DTU Chemistry and other research partners, you will conduct high-quality research bridging fundamental chemical processes and practical applications in resource recovery and water treatment.
Experience with process design, experimental validation, environmental impact assessment or the development of technologies towards pilot scale will be considered an advantage.
As a formal qualification, you must hold a PhD degree (or equivalent).
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. In addition, supplements can be negotiated in accordance with DTU's salary structure for scientific staff: https://www.inside.dtu.dk/en/human-resources/during-employment/salary/salary-structures.
