Pre-combustion carbon dioxide capture by gas-liquid absorption for Integrated Gasification Combined Cycle power plants

► The energy-related consumption was evaluated on a IGCC-based pre-combustion capture technology. ► Different physical and chemical solvents were used to estimate heat and power integration of the main plant sub-systems. ► Selection of solvents, quantification of carbon capture energy penalty, capital costs estimations was evaluated in details. ► The evaluation was based on modeling and simulation work in Aspen Plus engineering software.
