“…For the MEA process, we employ the following specific duty requirements: solvent regeneration heat, 3.68 MJ th /kg CO 2 provided at 407 K; compressor work, 375 kJ e /kg CO 2 ; and pump work, 40 kJ e /kg CO 2 . The same duty requirements were used in our previous work [14,22], and are based upon values provided by the Integrated Environmental Control Model (IECM), version 8.0.2, and other published literature [23][24][25]. Our representations of all of the CO 2 capture processes, including the MEA process, are consistent with an assumed reboiler approach temperature of 10 K. The piperazine process is very similar to the MEA process, and uses similar equipment but with a different solvent.…”

The optimized performance of two advanced CO 2 capture processes is compared to that of a monoethanolamine (MEA) baseline for a gas-powered CO 2 capture retrofit of an existing coal-fired facility. The advanced temperature-swing processes utilize piperazine and mixed-salt solvents. The mixed-salt treatment involves the use of ammonia for CO 2 absorption and potassium carbonate primarily to control ammonia slip. The processes are represented in terms of energy duty requirements within a modular heat integration code developed for CO 2 capture modeling and optimization. The model includes a baseload coal plant, a gas-fired subsystem containing gas turbines and a heat recovery steam generator (HRSG), and a CO 2 capture facility. A formal bi-objective optimization procedure is applied to determine the design (e.g., detailed HRSG components and pressure levels, gas turbine capacity, CO 2 capture capacity) and time-varying operations of the facility to simultaneously maximize net present value (NPV) and minimize total capital requirement (TCR), while meeting a maximum CO 2 emission intensity constraint. For a realistic scenario constructed using historical data, optimization results indicate that both advanced processes outperform MEA in both objectives, and the mixed-salt process in turn outperforms the piperazine process. Specifically, for the scenario considered, the base case mixed-salt process achieves 16% greater NPV and 14% lower TCR than the MEA process, and 10% greater NPV and 5% lower TCR than the piperazine process. A five-case sensitivity study of the mixed-salt process indicates that it is competitive with the piperazine process and consistently outperforms the MEA process.

“…Our model includes heat and work requirements for solvent regeneration, compression, and pumping (pumps and blowers). We consider the default amine CO 2 capture design for a pulverized coal plant in IECM 8.0.2, and use data from IECM and other sources (Berkenpas et al, 2009;Rubin et al, 2007;Jassim and Rochelle, 2006). Regeneration heat duty is 3.68 MJ th /kg CO 2 .…”

“…The required input for the evaluation of CO 2 capture costs via absorption technology is obtained from the Integrated Environmental Control Model developed by Rubin (2010). A 600 MW power plant with monoethanolamine (MEA) absorption was simulated, resulting in a flue gas of 666 kg/s containing 14 vol.% CO 2 (on a dry basis), which is similar to the flue gas composition as used in the evaluation of the cryogenic concept.…”

“…Subsequently, a sensitivity analysis of some key process parameters is discussed. Finally, our results will be compared to the results of economic studies on CO 2 capture via amine scrubbing (Rubin, 2010) and membrane technology (Merkel et al, 2010).…”
