摘要： The invention relates to a process for the treatment of a water stream comprising water, a carbonate salt and/or a hydrogen carbonate salt, and one or more additional salts, comprising the steps of: a) subjecting the water stream to bipolar membrane electrodialysis, resulting in a gas stream comprising carbon dioxide and a treated water stream comprising water and acid equivalents of the one or more additional salts; and b) removing the acid equivalents of the one or more additional salts from at least a portion of the treated water stream resulting from step a).

摘要： Techniques according to the present disclosure include capturing carbon dioxide from a dilute gas source with a CO2 capture solution to form a carbonate-rich capture solution; separating at least a portion of carbonate from the carbonate-rich capture solution; forming an electrodialysis (ED) feed solution; flowing a water stream and the ED feed solution to a bipolar membrane electrodialysis (BPMED) unit; applying an electric potential to the BPMED unit to form at least two ED product streams including a first ED product stream including a hydroxide; and flowing the first ED product stream to use in the capturing the carbon dioxide from the dilute gas source with the CO2 capture solution.
