Electrodialytic separation of gas from aqueous carbonate and bicarbonate solutions
First Claim
1. A process for producing a gas using an electrodialysis apparatus comprising:
- flowing at least a first solution, and a second solution into the electrodialysis apparatus, the electrodedialysis apparatus comprising two axial support members sealingly coupled to define a housing enclosing an electrodialysis stack;
flowing an electrode solution into the electrodialysis apparatus;
pressurizing the electrodialysis apparatus at a stack pressure;
applying a voltage to the electrodialysis stack of the electrodialysis apparatus such that a dissolved gas is generated in the second solution;
flowing the second solution out of the electrodialysis apparatus;
regenerating the gas out of the second solution; and
collecting the gas.

Abstract
A process for producing a gas using an electrodialysis apparatus includes flowing at least two solutions and an electrode solution into the apparatus, pressurizing the apparatus at a stack pressure, applying a voltage to the apparatus'"'"'s electrodialysis stack so a dissolved gas is generated in the second solution, flowing the second solution out of the apparatus, regenerating the gas out of the second solution, and collecting the gas. A process for generating a product, like a gas, liquid, or supercritical fluid, using an electrodialysis apparatus includes flowing at least two solutions and an electrode solution into the apparatus, adjusting the temperature and pressure so the product will be generated from the second solution, applying a voltage to the electrodialysis stack of the apparatus so that the product is generated in the second solution, flowing the second solution out of the apparatus, and regenerating the product from the second solution.
