About the position

As a PhD Candidate with us, you will work to achieve your doctorate and, at the same time, gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia.

Department of Chemical Engineering seeks a PhD candidate to investigate solvent degradation and its impact on amine-based CO2 capture plants.

This position at the Department of Chemical Engineering at NTNU focuses on chemical absorption and, more specifically, on the modelling of solvent degradation. Carbon dioxide is the primary greenhouse gas emitted through human activities, and the development and implementation of technologies for emission reduction are of great importance. Of the various methods to separate CO2 from industrial gases, absorption-based CO2 capture using aqueous alkanolamine solutions has reached the commercial stage. One of the remaining challenges is solvent degradation, the irreversible transformation of an absorbent solution into other compounds, that may cause equipment corrosion, amine loss, fouling, foaming, and finally reduction of CO2 absorption capacity.

This PhD work focuses on the modelling of liquid phase solvent degradation. The aim is to increase our understanding on how to design cost-effective CO2 capture plants and how process conditions impact degradation.

Your immediate leader will be the Head of Department.

Duties of the position

Conduct independent research in collaboration with the project team. The activities include:

Literature review on solvent degradation and corrosion
Developing a validated solvent degradation
Process simulations of absorption-based CO2 capture with different process designs and industrial cases
Combine the solvent degradation model with the simulation model and evaluate how the process conditions and process design impact solvent degradation and process performance.
Assessment of the results, including evaluation of simplifications and uncertainties and their impact on the results
Present the performed work and progress internally and externally
Publish the results in recognized scientific journals
Take part in the mandatory PhD research education program to complete the doctoral education until obtaining a doctorate

The candidate is further expected to:

Participate actively in group and institute activities.
Collaborate with other PhD candidates and research partners
Contribute to the supervision of master's students

Be prepared for changes to your work duties after employment.

Required selection criteria

You must have experience in modelling using Matlab or Python.
You have solid experience using process simulator AspenPlus or Hysys, and you have used them to simulate absorption processes.
You have experience with absorption processes.
You have knowledge of the chemistry of ionic solutions and are interested in learning more about solvent degradation chemistry.
You have experience in performing techno-economic assessments for chemical processes
You must have an academically relevant background in Chemical Engineering or equivalent.
You must have a Master's degree in Chemical Engineering or equivalent. Your course of study must correspond to a five-year Norwegian course, where 120 credits have been obtained at master's level. Master's students can apply, but the master's degree must be obtained and documented within 3 months after the start of the position.
You must have a strong academic background from your previous studies and have an average grade from your Master's degree study, or equivalent education, which is equal to B or better compared to NTNU's grading scale. If you do not have letter grades from previous studies, you must have an equally good academic foundation. If you have a weaker grade background, you may be considered if you can document that you are particularly suitable for a PhD education.
The position requires spoken and written fluency in English.
You must meet the requirements for admission to the faculty's doctoral program (https://www.ntnu.edu/nv/phd).
