 The overall goal of our work is to find innovative solutions to the climate challenge. This comprises finding new solutions as well as improving existing ones with regard to optimization of the CO2 capture process and related environmental challenges. It furthermore comprises collection and transportation solutions for captured CO2.

The CO2 research work done within the TUC and Tel-Tek organisations is closely interwoven. The overall goals are shared. The organisation is project oriented although there is a common red thread connecting projects.

It is an ambition to achieve the above by engaging in work at both a regional and national level as well as internationally.
 

CO2-lab is both an experimental laboratory and a mind lab.

On a practical level, our research on post combustion capture of CO2 involves the following:

  • Modelling of CO2 capture processes
  • Control of CO2 capture processes
  • Improveded understanding of the amine technology
  • Environmental improvement of CO2 capture processes
  • Improved knowledge about environmental consequences of amine use
  • Further development of our software tools applied to CO2 capture processes
  • CO2 capture experiments
  • Contributing to establishing pilot scale facilities, with a particular focus on CO2 capture from an environmental point of view
  • Establishment and development of networks via national and international cooperation

Main focus areas in our post-combustion CO2 capture research:

  • Minimization of energy consumption
  • Minimization of capital expenditure
  • Minimization of amine degradation
  • Handling of amine waste
Environmental impacts of CO2 capture technologies:
  • Minimization of amine degradation and amine waste generation, including the impact of waste gas composition
  • Different ways of handling amine waste
  • Possible environmental impacts of pre-combustion and oxy-combustion
  • Laboratory experiments will be part of the study

Modelling, control and monitoring of CO2 capture:

  • Detailed studies of the flow within process equipment units
  • Flow modelling of gas distribution in the absorption and stripper columns, focusing on uniform load
  • Dynamic process simulation of the post combustion capture process
  • Analysis and characterization of regenerated absorbent
  • Analysis and characterization of emissions to the atmosphere (CO2 fraction, amine concentration etc)
  • Emissions monitoring systems
  • Emissions control systems
  • Integrated design of the process and the control system, in order to make the system as self-controlling as possible
  • Optimum operation of the heat-integrated process
Optimization and simulation of CO2 capture processes:
  • Utilization and improvement of modern simulation tools applied to existing and new CO2 capture processes and process equipment.
  • Use of Aspen Hysys (commercial process simulation tool) and Fluent (commercial CFD software) as simulation tools.
  • Use of Matlab to develop our own models.

Monitoring of other CO2 capture technology:

  • Pre-combustion
  • Oxy-fuel combustion
  • Chemical looping
  • Transport of CO2
  • The CO2 value chain in general
