CO2 desorption using high-pressure bipolar membrane electrodialysis

Energy & Environmental Science, 2011
The electrodialysis of gas evolving solutions may prove to be an important technology for many gas-separation applications, including CO2 and SO2 separation from mixed-gas streams. Progress on the use of electrodialysis for gas separation has been hampered by the increased resistance caused by gas bubbles on the surface of the electrodialysis membranes.

Utilization of Bipolar Membrane Electrodialysis for Salt Water Treatment

Water Environment Research, 2013
ABSTRACT: Bipolar ion‐exchange membranes, using polystyrene ethylene utylenes polystyrene (PSEBS) with polyvinyl alcohol as the intermediate, were fabricated and evaluated for their potential to remove secondary salts from lab‐prepared salt solutions. Experiments were carried out in batch re‐circulation mode.
