Abstract:
A method comprises flowing process solution and electrode solution into a BPMED apparatus, applying a voltage such that the process solution is acidified and basified and dissolved CO2 is generated, flowing the process solution out of the apparatus, and desorbing CO2 out of the process solution. A method for desorbing CO2 from an ocean comprises flowing seawater and electrode solution into a BPMED apparatus, applying a voltage such that dissolved CO2 is generated, flowing the seawater out of the apparatus, and desorbing CO2 out of the seawater. A method for producing a desalted solution and CO2 gas comprises flowing process solution and electrode solution into a BPMED apparatus that includes one or more three-compartment cells, applying a voltage such that the process solution is acidified, basified, and desalted, flowing the process solution out of the apparatus, and desorbing CO2 out of the process solution.
