CO2 capture using HS-3 solvent (aqueous mixture of 40wt% of 1-(2-Hydroxyethyl)pyrrolidine, 1-(2HE)PRLD and 15wt% of 3-amino-1-propanol, 3A1P) has been successfully demonstrated at Irving Oil Whitegate Refinery in Ireland with real flue gas, reaching TRL 6. TNO’s miniplant, an ATEX-compliant small-scale pilot plant, has been employed to capture CO2 from flue gases of four different sources of the Irving Oil Whitegate Refinery. The flue gases have varying content of CO2, O2 and other impurities in order to degrade and stress-test as much as possible the stability of the solvent. In order to study the multi-absorber concept for capturing CO2 from different stacks proposed in REALISE, the same solvent was used during all the demonstration campaigns.
WP2 - Capture
Demonstrating pilot-scale CO2 capture with optimised solvent
- Demonstrations at Irving and Tiller
- Solvent and emission management
- Cost minimisation
- CO2 quality
The main aim is to demonstrate CO2 capture from refinery stacks using the solvent optimised in WP1. This will include degradation mitigation technologies and solvent reclaiming. There will be demonstration campaigns at Irving’s Cork refinery and at SINTEF’s Tiller pilot focusing on solvents and emissions, and on cost minimisation respectively.
