The presence of particulate impurities in the form of fly ash within a postcombustion carbon capture application will be difficult to avoid. In this work, the effect of fly ash on the membrane performance for both black- and brown-coal applications is examined. Deposits of either black- or brown-coal fly ash on the membrane surface had no impact on CO2 permeance when totally dry. In contrast, deposits of a mixture of fly ash and liquid water caused the membrane permeance to fall below the level expected from the presence of liquid water alone. For both black-coal fly ash (Sauter mean diameter 9.2 μm) and brown-coal fly ash (Sauter mean diameter 9.8 μm), the permeance recovers to over 98% of ..View full abstract
