“…Figure 3 shows the overall process flow diagram. Since there has been less research into CO 2 -selective polymeric membranes than H 2 -selective polymeric membranes, we chose an optimistic value of CO 2 /H 2 selectivity of 50, which is greater than typical values for CO 2 /H 2 selectivity measured so far [16,[33][34][35][36], most of which are on the order of 10. In addition, we assumed that the selectivity of CO 2 to all other species was 50.…”

Abstract:We have conducted comprehensive exergy analyses of three integrated gasification combined cycle with carbon capture and storage (IGCC-CCS) power plant configurations: (1) a baseline model using Selexol™ for H 2 S/CO 2 removal; (2) a modified version that adds a H 2 -selective membrane before the Selexol™ acid gas removal system; and (3) a modified baseline version that uses a CO 2 -selective membrane before the Selexol™ acid gas removal system. While holding the coal input flow rate and the CO 2 captured flow rates constant, it was determined that the H 2 -selective membrane case had a higher net power output (584 MW) compared to the baseline (564 MW) and compared to the CO 2 -selective membrane case (550 MW). Interestingly, the CO 2 -selective membrane case destroyed the least amount of exergy within the power plant (967 MW), compared with the Baseline case (999 MW) and the H 2 -membrane case (972 MW). The main problem with the CO 2 -selective membrane case was the large amount of H 2 (48 MW worth of H 2 chemical exergy) remaining within the supercritical CO 2 that exits the power plant. Regardless of the CO 2 capture process used, the majority of the exergy destruction occurred in the gasifier (305 MW) and gas turbine (~380 MW) subsystems, suggesting that these two areas should be key areas of focus of future improvements.

Given the increasing size of CO 2 -generating industries and the mounting awareness of their environmental impact, carbon-management technologies are expected to play an important role in curtailing environmental emissions in coming years. A major challenge in carbon management is the development of cost-effective, technologically compatible, and effi cient CO 2 capture and storage technologies. The development of energy-effi cient solvent, solid-sorbent, and membrane materials to capture CO 2 from industrial exhaust streams can take improvements in process effi ciency one step further. Also, the permanent storage of CO 2 in geologic formations is critical to the success of carbon-management technologies and requires better understanding of interactions of CO 2 with underground materials. These and other materials challenges must be solved to make carbon capture and storage an economically viable and reliable technology to be adopted by the power and product manufacturing industries.

“…Pressure increase could cause significant decrease of permeability and selectivity [18] and significant power loss (for example, as much as 20% of the power plant output for 5 bar compression) due to the dilute concentration of CO 2 in the flue gas [7]. In comparison, under lab vacuum permeate conditions, a cost of $54/ton CO 2 captured was avoided, which is equivalent to 2/3 capture cost of a pressurized bed [12].…”

“…Two staged pressure membrane (with 4 bar pressure at the first stage) was modeled and a cost of $57/ton CO 2 captured was avoided with final CO 2 concentration of 90% [18,19]. Two staged vacuum membrane was simulated to achieve 90% capture efficiency at a cost of $39/ton CO 2 captured [7].…”

CO 2 capture from post combustion does not need significant alteration of the current power generation facilities and is therefore of more interests to the research and industrial circles. Polymeric membrane separations, which are based mainly on physical phenomena, are easy for operation and to scale up. The details and future research trends are covered in this most updated review, which serve as an excellent technique reference for the research circle and technology evaluation for the related industrial circle.
