Abstract:
The urgent need for efficient technology to reduce CO2 emissions is increasingly highlighted to
combat climate change. Currently, the most successfully commercialized technology for CO2 capture is
perhaps amine capture technology. CO2-containing waste gas is passed through an absorber with amine
solution as an absorbent. More than 90 % of CO2 can be absorbed chemically in the amine solution. One of the
commonly used absorbents is aqueous monoethanolamine (MEA) solution. If MEA is used, carbamate and
ammonium ions form from the reaction between MEA and CO2 after absorption. This spent absorbent is
regenerated in a reboiled stripper, which requires heat to operate, to reclaim the absorbent and release highconcentration
CO2 gas. This project studies electrodialysis as an alternative means for absorbent regeneration
with co-conversion of CO2 into fine CaCO3 particles, converting waste into a potential product. 30 wt%
monoethanolamine (MEA) presaturated with 1 atm CO2 was used to imitate industrial spent absorbent. CaCl2
solution was used as a calcium source. In some experiments, NaCl was added to carbamate solution and/or
HCl was added to CaCl2 solution to study their effects. Our electrodialysis system offered a faradaic efficiency
of 49% for CaCO3 production at a current of 0.1 A. A key issue apart from this still low faradaic efficiency was
precipitation of CaCO3 directly on electrodialysis membrane. It was found that the addition of NaCl to
carbamate solution minimized on-membrane precipitation of CaCO3. This study aims to improve both the
faradaic efficiency and the membrane-precipitation issue
