CO2 R&D Needs
• Reduce the power penalty associated with CCS
• Compression must be integrated and optimized
with various capture schemes
– Amine solvents
– Chemical looping
– Membranes
• Reliability of the equipment important
• Beneficial to leverage existing compression
technology
• Equation of state near critical point and with
mixtures
Southwest Research Institute
Motivation of Current Project
• CO2 capture has a significant compression penalty
• Final pressure around 1,500 to 2,200 psia for
pipeline transport or re-injection.
• Based on a 400 MW plant, the typical flow rate is
~600,000 to 700,000 lbm/hr.
• Project goal: Double-digit reduction of compression
power for CO2 capture
• Many thermodynamic processes studied.
• Several challenges with the application discussed.
• Research applicable to PC, Oxy-Fuel,IGCC &
NGCC
