“…Van Wagener et al (2014) simulated a carbon capture process with 8 m PZ to estimate the steam, electricity, and cooling water requirements. Kvamsdal et al (2014) studied the integration of a configuration based on high-pressure flash regeneration with the upstream power plant. They found that a power plant integrated with the optimal PZ-based capture plant had a net electric efficiency of 37.4%, which is 7.2% less than the reference power plant without CO 2 capture.…”

“…While in thermodynamic simulations, to assess energy consumption of CO 2 capture processes, a measure of the energy consumption related to CO 2 capture is given by the specific primary energy consumption for CO 2 avoided (SPECCA, GJ/t CO 2 ) (Kvamsdal et al, 2014;Sanchez Fernandez et al, 2014), which is defined as:…”

“…Goto et al [8] reviewed the impact of integration of the PCC plant for a number of alternative chemical solvents, and revealed that the efficiency penalty can be reduced to 8.0-8.5% points with NH 3 [16,17] and to 8.5% points with amine-blends, such as methyldiethanolamine/piperazine [18]. Moreover, studies by Kvamsdal et al [19] and Van Wagener et al [20] showed that the use of piperazine as a solvent can reduce the efficiency penalty to 7.0-7.2% points. An alternative to chemical solvent absorption is application of novel CO 2 membranes, which has the potential to reduce the efficiency penalty to 6.4-8.5% at a low cost [21].…”

“…Lower reboiler heat duty of chemical absorption systems can be achieved by, for example, using an improved process configuration (e.g., absorber intercooling, lean vapor compression, split-stream, etc. [24][25][26]) and/or solvents with better characteristics [18,23,[26][27][28].…”

Coal-fired power plants are the largest source of anthropogenic carbon dioxide (CO 2 ) emissions into the atmosphere, with more than 9.5 billion tonnes of CO 2 emitted annually. In order to mitigate the emissions of CO 2 from coal-fired plants, several measures were proposed, such as increasing the efficiency of the plants, cofiring biomass with coal, and capturing and storing CO 2 deep underground. Among these measures, the use of biomass, which is considered one of the most cost-effective renewables and, in addition, carbon neutral, combined with CO 2 capture and storage will play an important role toward reducing the fossil-based CO 2 emissions. In this study, we investigated in detail the performances of pulverized coal combustion plants with direct cofiring of biomass and integrated with an amine-based postcombustion capture technology. All the systems were modeled and simulated using the process simulation software Aspen Plus. The results indicate that cofiring 10% of biomass in a coal-based power plant only slightly affects the energy performance of the plant, reducing the net efficiency by 0.3% points. The addition of an amine capture system to both the coal-fired and biomass cofiring plants further reduces the efficiency of the plants by more than 10% points. Analyzing the effect of various CO 2 capture process parameters on the heat, solvent and cooling water requirements, and on the overall plant performance, it was found that the concentration of amine in the solution is the most important parameter. The results showed that the net electrical efficiency increases for systems using higher amine concentrations. Further, we investigated the effect of systems with lower heat requirement for solvent regeneration on the plant gross/net power output and also analyzed the plant performances under a flexible CO 2 capture efficiency.
