PhD scholarship in Downstream Process Modeling, Design, and Optimization of Plastic (PET) Chemical Recycling

jobbeskrivelse:

The Department of Chemical and Biochemical Engineering at DTU invites applications for a 3-year PhD position in downstream processing of depolymerized polyethylene terephthalate.

Polyethylene terephthalate (PET) is a plastic that is not recycled but reused inevitably ending to landfill or combustion at the end of its life cycle, posing a serious economic and environmental threat. Depolymerizing PET to its monomers can lead to significant savings of capital and resources in comparison with producing virgin PET.

As part of the efforts of an international consortium to realize a chemical recycling plant (comprising of a core de-polymerization unit and a downstream treatment unit), DTU Chemical Engineering focuses on the downstream units for the recovery and purification of final products, that is ethylene glycol and terephthalic acid as virgin-grade PET monomers.

Responsibilities and tasks

The main purpose of this PhD project is designing a process for efficient purification of PET monomers. To do so, you will need to work with:

• Experimental determination of physical properties.
• Building of thermodynamic models able to predict these properties
• Combining thermodynamic models with process simulation tools in order to design the downstream processes.
• Validating the developed models against lab scale and pilot plant experiments.
• Optimizing processes through process simulation and techno-economic analysis.
• Developing the whole closed process cycle and proposing alternatives.

Qualifications

Candidates should have a two-year master's degree (120 ECTS points) in chemical engineering or similar and have a background in computer modelling and simulation. Previous experience with experimental determination of physical properties as well as with process simulation tools such as ASPEN HYSYS and ASPEN Plus will be highly appreciated.

Approval and Enrolment

The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide. http://www.dtu.dk/english/Education/PhD/Rules/PhDguide
