Background and activities

Teaching and Supervision

I’m particularly interested enhancing learning by introducing active learning methods. These include case- and problem-based learning and flipped class room for smaller classes and variations of these in large auditorium teaching.  I’m also interested in developing technologies that support student learning outside the classroom. My next big goal is to introduce choose your own adventure –learning to improve the student motivation and learning in one of my courses.

I’m currently responsible for the following courses/modules:  

Additionally, I’m supervising

Previous teaching responsibilities: TKP4852 EIT- Environmentally friendly mineral processing - is it possible? (2015), TKP4852 EIT - CO2 capture (2012-2014) 

 

Research Areas

My main research interest are related to acid gas removal using absorption technology. Currently, the modelling and experimental activities focuses on development and characterization (including solvent stability studies) of solvents for H2S and CO2 removal. Additionally, my team is working on fitting of thermodynamic models, modelling of absorption kinetics and process simulations.

Project participation

Projects Low Energy Penalty Solvents (LEPS) and Evolutionary de novo design of absorbents with optimal CO2 capturing properties (DeNOVO) develop new solvents for CO2 capture. Additionally, faculty funded research on potential of hybrid solvents for biogas upgrading systems increases our knowledge on the interaction of different organic solvents on the performance of the amine-organic diluent blends. In 3rd Generation solvent membrane contactor – project the aim is on the improvement of absorption process with low solvent losses by developing a membrane contactor with low mass transfer resistance for CO2 and high resistance for the solvent components. 

In ALIGN-CCUS and AEROSOLV –projects we are involved in activities focusing on modelling of mist behavior in the absorber. Norwegian CCS research centre, ALIGN-CCUS   and the Department of Chemical Engineering support the activities on solvent degradation and corrosion focuses on identifying the amine structure giving corrosion and degradation (in the process and in the nature). SUBPRO and Gas Technology Centre NTNU-SINTEF (GTS) have been funding investigations of combined H2S is removed and hydrate control in subsea.

Finally, our laboratory infrastructure related to absorption studies are part of ECCSEL providing access for researchers outside NTNU to the intrastructure.

Selected previous projects: HiPERCAP, iCAP, SOLVIT SP4 Educational Programme.

 

Laboratory equipment:

The laboratory equipment available for solvent characterization and development can be divided into three separate infrastructures:  equipment for kinetics studies, vapor-liquid equilibria studies and solvent degradation studies.

All the equipment is part of ECCSEL-infrastructure and short overview of the equipment can be found in the ECCSEL web-pages.
