About the job

The Process and Power Program, Department of Energy and Process Engineering (EPT) at the Norwegian University of Science and Technology (NTNU) is seeking a PhD Candidate to research better process systems for waste plastic gasification using state of the art process systems engineering methodologies. This project considers the design, modelling, simulation, optimization, and eco-technoeconomic analysis of the downstream systems that clean the syngas, convert it to olefins, and eventually to virginal plastics. Some of the big unanswered questions include determining the optimal system designs for various kinds and qualities of plastics feeds, whether oxidative coupling of methane or methanol-to-olefins routes are better, and what are potential environmental benefits / cost tradeoffs at the supply chain / national level. The primary goal is the synthesis and analysis of excellent designs that are highly likely to reduce plastic wastes in our society with a net economic and environmental benefit for all. 

For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.

It is also an exciting opportunity to work with an elite team of researchers who are tackling the most relevant and urgent problems in sustainable energy systems. The EPT department contains a diverse range of expertise in chemical engineering, mechanical engineering, energy systems engineering, process engineering, industrial ecology, industrial economics, life cycle assessment, and other specialities. We are looking for someone to join our team and contribute their expertise to high-impact research that has the potential to change our world for the better.

Your immediate leader is Prof. Thomas A. Adams II.

Duties of the position
  • Perform academic research relating to the project, including proposing new ideas and directions.

  • Interact and collaborate with our team of academics across multiple disciplines.

  • Communicate results effectively through research journal publications, conference presentations, explanatory videos, lectures, social media posts, or other forms of communication to a diverse range of audiences.

  • Assist with and participate in related scholarly activities in the Process and Power group as a part of your own academic training. This may include attending, leading, or organizing talks and meetings; assisting with academic event logistics and organizations; or reviewing and providing feedback on the work of colleagues.

Required selection criteria

1)      You must have a professionally relevant background in chemical engineering, energy process systems engineering, or a closely related field.

2)      Your education must correspond to a five-year Norwegian degree program, where 120 credits are obtained at master's level.

3)      You must have a strong academic background from your previous studies and an average grade from the master's degree program, or equivalent education, which is equal to B or better compared with NTNU's grading scale. If you do not have letter grades from previous studies, you must have an equally good academic basis. If you have a weaker grade background, you may be assessed if you can document that you are particularly suitable for a PhD education.

4)      Master's students can apply, but the master's degree must be obtained and documented by May 2024.

5)      You must meet the requirements for admission to the faculty's doctoral program (English link | Norwegian link ).

7)      Demonstrated expertise in chemical process modelling and simulation software such as Aspen Plus, Aspen Hysys, ProMax, Pro/II, gProms, or similar packages.

8)      The research proposal, demonstration of expertise, and quality of the academic works must meet the threshold of excellence.

The appointment is to be made in accordance with Regulations on terms of employment for positions such as postdoctoral fellow, Phd candidate, research assistant and specialist candidate and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant. 

Preferred selection criteria

1) A strong peer-reviewed research publication record (including in-press or accepted works) in chemical process systems engineering, energy systems engineering, or a closely related field that demonstrates significant independent contributions of the researcher. Submitted works undergoing peer review can be considered in lieu of published research output.

2) Training in the application and theory of stochastic and deterministic global optimization methods, such as mathematical programming, swarm methods, etc.

3) Training in ISO 14040 series LCA methodologies.

4) Familiarity with LCA software and databases such as SimaPro or OpenLCA.

5) Training in techno-economic or eco-technoeconomic analyses methodologies.

6) Proficiency in at least one common programming language (Python, C++, Matlab, etc.)
