“…3,4 Usually for coal-based power plants, three fields widely investigated for CO 2 removal are oxygen-enriched combustion, postcombustion, and precombustion. 5 Oxygenenriched combustion has the advantage that CO 2 concentration in flue gas can be as high as 90% and is very easily concentrated further; however, it faces the difficulty of oxygen-enriched gas production and high energy cost. 6 For postcombustion, due to the low flue gas pressure and much lower CO 2 concentration, the capture of CO 2 is difficult and requires high capital investment and high energy cost.…”

Using 1-butyl-3-methylimidazolium dicyanamide ([bmim][DCA]) as the absorbent and either hydrophobized porous ceramic tubule or hydrophobized polyether ether ketone (PEEK)-based porous hollow fiber membranes, we have carried out preliminary studies for CO2 removal from simulated precombustion syngas by a pressure swing membrane absorption process. We have used He as a surrogate for H2 (40% CO2 rest He) up to a temperature of 100 °C and a pressure of 250 psig. A novel 5-valve system was designed to improve product quality. The optimal duration for the key absorption step was determined, and the influence of helium-rich product withdrawal time was investigated. Temperature increase will degrade product quality, so adding polyamidoamine dendrimer of generation 0 to [bmim][DCA] will mitigate the temperature effect, and 15 wt % dendrimer in [bmim][DCA] showed the best performance. Feed pressure increase will degrade helium product quality, while it is beneficial for CO2 product quality, since more CO2 will be absorbed with a higher feed pressure. When feed gas pressure was 250 psig at CO2 side ∼88.2% CO2-enriched gas product was produced. Using a simulated two-stage large PEEK module system, with a 14.0% CO2 balance helium gas mixture, helium product with CO2 concentration as low as 4.2–5.8% could be achieved at different temperatures. A brief analysis has been provided to explain why a PEEK membrane module shows much better performance than the ceramic tubule.
