Carbon Capture - Post-Combustion Capture


CO2 Binding Organic Liquids Gas Capture with Polarity Swing Assisted Regeneration


Performer: Battelle Memorial Institute

Project No: FE0007466


Accomplishments


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.
