Industrial collaboration to solve aerosol emission from CO2 capture

Mar 08 2017

SINTEF, NTNU, Engie, Road, Uniper, TNO and TCM are collaborating on a solution to emissions from amine CO2 capture.

One of the most important research topics in post combustion CO2 capture is to control the emissions of amine and amine degradation products to the atmosphere. Aerosol-related emissions to air from amine absorbers for CO2 capture is a topic of increasing interest and concern.

Aerosolve is part of a larger scientific test campaign starting at Technology Centre Mongstad this summer, and is a good example of how several companies and organizations can collaborate with test activity at TCM, says Roy Vardheim, Managing Director of TCM.

The current project proposal is for 12 months, with startup at Technology Centre Mongstad in mid-2017. This serves the purposes of providing results pertaining to urgent issues in full-scale CO2 capture projects. The project receives 50% funding from Climit Demo. 

It is commonly known that flue gas pre-treatment, absorber configuration, operating conditions and solvent selection are factors that can minimize these emissions, but there is currently limited theoretical and experimental understanding of the physical/chemical mechanisms involved in the process and certainly insufficient knowledge to allow the techno-economic optimization of aerosol control at industrial scale.

There are also contradictory results reported in literature as to e.g. effect of various pre-treatment options. Establishment of reliable continuous measurement methodology for absorber aerosols and online process monitoring is needed in order to increase the availability of high quality data, underpin model validation, assess the effectiveness of abatement options, such as the use of wet electrostatic precipitators and Brownian diffusion filter techniques, and ultimately deliver reliable process monitoring and control.

Validated theoretical models and generic tools for flue gas pre-treatment design will be important tools for future process optimization of design. Therefore, it is of importance to demonstrate suitable treatment options under real and relevant conditions. This work will lead to the insights how to develop and operate CO2 capture plants with emission levels within the given emission permits.
