CO2 Corrosion Relevant to CCS

To mitigate the climate crisis and reduce the emissions of CO2 the carbon capture and storage (CCS) technology is one of the most viable options. The CCS technology is easily retrofitted to existing plants, however, optimization is still needed to minimize costs and shutdowns.

This project deals with CO2 corrosion and energy optimization for carbon capture in waste-to-energy plants.

CO2 corrosion is a major problem as it led to significant production losses and costly shut downs. In the presence of an aqueous liquid CO2 forms carbonic acid, which is highly corrosive towards metals and alloys resulting in enormous economic loss as equipment life time is shortening. CO2 corrosion leads to the formation of a solid FeCO3 layer which creates a protective barrier for further corrosion.

The first part of the study aims to create new fundamental understanding of the solubility of FeCO3, which will lead to better corrosion models, better prediction of corrosion rate, and better scale formation kinetics understanding. Measurements will be conducted in the laboratory and in the field, in the industry.

Waste-to energy plants are one of the contributors to increasing CO2 emissions. The second part of the project is a collaboration with Amager Ressource Center (ARC).

The purpose is to develop a less expensive and less energy consuming solution to capture CO2 at a waste-to-energy plant. This will be executed using a newly constructed mobile test unit (MTU) on site. Green solvents and different plant configurations will be tested.

The aim is to find the best solution in order for ARC to construct a pilot plant and by the end construct a full scale CC plant. Corrosion will be analysed onsite at ARC.
