PhD in Chemical Engineering on membrane processes for sugar applications, Lund University, Sweden

 

Description of the workplace

Lund University was founded in 1666 and is repeatedly ranked among the world’s top universities. The University has around 45 000 students and more than 8 000 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

The Department of Process and Life Science Engineering (PLE) covers a wide range of industrially relevant research, including e.g. plant-based meat analogues, carbon capture and formulation and purification of biopharmaceuticals. The Membrane group (https://www.membranegroup.lu.se/) at PLE is the most established Membrane Group in Sweden and has with MemLab – the Industrial membrane process research and development centre – an excellent infrastructure to develop and optimize membrane processes from lab to pilot scale.

Subject description

The project is a collaboration with Nordic Sugar A/S. Nordic Sugar A/S as part of the Nordzucker Group with production facilities in Europe and Australia is one of the worldwide leading sugar manufacturers from beet and cane and also a producer of bioethanol and animal feed.

Thus the project is to be carried out in close cooperation with industry and aims to reduce the lime usage in beet raw juice purification by developing a process for the clarification of raw beet juice using ultrafiltration as a key separation unit. The ultrafiltration process will first be optimized on lab-scale with regards to membranes and process conditions including cleaning and pre-treatment. Potential post-treatment processes to improve sugar concentration and purification on lab-scale will also be investigated. The optimized process is then to be scaled-up to industrial pilot scale based on which an economical evaluation and life cycle assessment will be carried out for the full-scale process.
