Systems and methods for electrochemical target species separation are described herein. In some embodiments, a target species can be transported, in response to an applied voltage, from a fluid in a first electrically conductive tube (e.g., a tubular electrode) that has a low concentration of the target species to a fluid in a second electrically conductive tube (e.g., a tubular electrode) that has a high concentration of the target species. The transport of the target species may involve the diffusion of the target species through porous walls of the first and second tube. In some embodiments, the target species comprises gases such as acid gases (some of which may be commonly exhausted from powerplants and/or industrial processes).
An electrochemical apparatus for target species separation, comprising:
A method for separating a target species, comprising:
(canceled)
An electrochemical cell comprising a multiplicity of hollow inlet tubes and a multiplicity of hollow outlet tubes, wherein the tubes are configured to transport gases, and wherein the tubes are surrounded by an electrolyte solution, wherein the walls of the tubes comprise a porous, electrically conductive membrane, wherein the membrane is configured to allow diffusion of the gases and prevent liquid crossover into the gases, wherein the tubes are electrically connected to a means of applying a voltage between the inlet and outlet tubes, wherein the electrolyte solution upon applying the voltage comprises reactants that react with CO2 transported into the inlet tubes, and produce CO2 transported out of the outlet tubes.
