Pacific Northwest National Laboratory (PNNL) is performing testing and optimization of three advanced carbon dioxide (CO2)-binding organic liquid (CO2BOL) water-lean formulations for post-combustion CO2 capture. PNNL leverages its carbon capture laboratory infrastructure and testing methodologies to collect comprehensive physical and thermodynamic property test data for each solvent. Aspen Plus® models utilize the physical property translations of the collected data to project the energetics (e.g., reboiler duty, parasitic load) and preliminary capture costs.
