Carbon Dioxide Recovery by Membrane Assisted Crystallization

Authors: Wenyuan Ye, Jiuyang Lin, Patricia Luis, Bart Van der Bruggen

Abstract:

This study addresses the effect of impurities on the crystallization of Na2CO3 produced within a strategy for capturing CO2 from flue gases by alkaline absorption. A novel technology - membrane assisted crystallization - is proposed for Na2CO3 crystallization from mother liquors containing impurities. High purity of Na2CO3•10H2O crystals was obtained without impacting the performance of the mass transfer of water vapor through membranes during crystallization.

Keywords: Carbon dioxide recovery, crystal morphology, membrane crystallization, purity.
