Abstract
Effluent water is combined with carbon dioxide sourced from a carbon dioxide-containing emission stream to produce a reaction solution. The pH of the reaction solution is controlled to induce precipitation of a carbonate salt from the reaction solution.
Claims15
A method comprising:
- combining effluent water with carbon dioxide sourced from a carbon dioxide-containing emission stream to produce a reaction solution;
