Carbon Capture - Post-Combustion Capture
CO2 Binding Organic Liquids Gas Capture with Polarity Swing Assisted Regeneration
Performer: Battelle Memorial Institute
Project No: FE0007466
A comprehensive study to quantify all physical and thermodynamic properties of the new solvent system was completed. A preliminary EH&S evaluation was conducted.
Kinetic testing was performed with synthesized CO2BOLs using Battelle’s wetted wall apparatus. Preliminary findings indicated that the CO2BOLs absorb CO2 at lower partial pressures than previously measured.
Identified third generation CO2BOLs with reduced viscosity and increased water tolerance.
Confirmed PSAR impacts on equilibrium loading.
A new thermodynamic process model in Aspen Plus™ was created to indicate commercial feasibility. Model development included a new thermodynamic model to capture the unique chemistry of CO2BOLs.
A baseline case of the model was developed as a direct comparison to NETL’s subcritical pulverized coal plant with CO2 capture; case 10 in the report Cost and Performance Baseline for Fossil Energy Plants Volume 1: Bituminous Coal and Natural Gas to Electricity.
Reviewed initial feasibility study findings with NETL and obtained approval to proceed with optimization and bench-scale studies.
