Industrial Crystallization for Resource Recovery

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

The world is currently approaching a shortage of freshwater along with limited energy resources. Eutectic freeze crystallization (EFC) is a novel technology that can be used to simultaneously recover pure water and salts from concentrated brines. Successful implementation of EFC is expected to lead to more energy-efficient and environmentally sustainable processes where water can be recycled, and waste minimized. This technology has until recently only been studied at lab- and pilot-scale at a proof-of-concept level. The first full-scale plant for treatment of mining wastewater has recently been constructed in South Africa. There is critical need for further research and for a wider dissemination of the industrial know-how in order for EFC to achieve its full potential.

The overall aim of this project is to investigate the methodologies of this particular type of crystallization process, for the purpose of increasing the underlying fundamental knowledge and understanding of key aspects, such as the kinetics of nucleation and growth of targeted salts, the mechanisms involved in incorporation of impurities, and how to mitigate the problem of ice scaling. The research will be related to case studies from industry, which will define targeted impurities and conditions. The project will benefit from an industrial reference group and from an on-going collaboration project together with the University of Cape Town focused on crystallization for resource recovery.

We are looking for a person with documented knowledge in chemical engineering and with an interest in developing their knowledge in the field of crystallization. The position involves doctoral studies and up to 20% teaching in chemical engineering courses.

The start date is open for discussion, but we would prefer to see the position filled no later than the first of February 2021. The project is funded by Formas.

Third-cycle subject: Chemical Engineering

Supervision: The doctoral student will be supervised by Assoc. Prof. Kerstin Forsberg and Assoc. Prof. Michael Svärd

To be admitted to postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance), the applicant must have basic eligibility in accordance with either of the following:

• passed a second cycle degree (for example a master's degree),
• completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
• acquired, in some other way within or outside the country, substantially equivalent knowledge.
• Special eligibility is education at advanced level in chemical engineering or a related subject.

In addition to the above, there is also a mandatory requirement for English equivalent to English B/6, read more here

In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:

• independently pursue his or her work
• collaborate with others,
• have a professional approach and
• analyse and work with complex issues.

Furthermore, knowledge in separation processes, in particular crystallization, is a merit. Good laboratory skills is also a strong merit.

After the qualification requirements, great emphasis will be placed on personal competency.

Target degree: Doctoral degree

Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years ' time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time.
