Post-combustion CO2 capture technologies - a review of processes for solvent-based and sorbent-based CO2 capture

This paper provides a short review of the multitude of processes proposed for solvent-based and sorbent-based post-combustion CO2 capture. (Membrane-based systems, another important technology for CO2 capture is outside the scope of this review.) The majority of process configurations discussed in the open literature focus on reducing the energy penalty with little consideration of capital cost or operability - key factors for industrial implementation. This paper highlights advances in all three areas and identifies opportunities for future research.
