The technology combines salts present in industrial wastewater with carbon dioxide in an electrochemical cell to mineralize the carbon dioxide in the form of high-value oil-field chemicals such as acids and carbonate salts. This coupled process simultaneously removes CO2 and desalinates the wastewater or brine. The amount of CO2 that can be mineralized is dependent on the salt content of the wastewater. Designed as a process operated from a modular facility, the technology can be easily scaled based on wastewater volume treatment requirements. The modular design also means the technology will be easy to transport and simple to operate on site.
