Screening solvents properties for CO2 capture based on the process performance

Deployment of carbon capture and storage (CCS) technologies is the one of the key strategies to decarbonise the energy system in order to abate the consequences of climate change. Nevertheless, carbon capture is facing some challenges that are deterring its implementation. The capital costs are considered to be very high, and the energy required for solvent regeneration imposes an efficiency penalty on the power plant with which it is integrated. Therefore, it is imperative to seek for opportunities to reduce the overall cost of the CCS. This work focuses on the design strategies for new solvents for the capture of CO2 from power plants. We have developed a process performance indexed screening tool to assess the suitability of new solvents based on economic, energetic and environmental performance indices. The physicochemical properties of the solvents that lead to reduction of the capture cost have been determined. (C) 2017 The Authors. Published by Elsevier Ltd.
