The project will demonstrate the feasibility of a novel and innovative approach for managing and maximizing reuse of waters produced for reservoir pressure and plume management during CO2 injection. This approach aims to be environmentally sustainable. 

The produced brines will undergo pre-treatment and/or pre-concentration (if total dissolved solids is < 50,000 mg/L) prior to evaporation. Following evaporation, the very concentrated waste brine and solids will undergo solidification/stabilization to form an easily manageable solid that can be landfilled. Moisture in the flue gases from the evaporation process will be condensed using supercritical CO2 as the working fluid to recover water for reuse.

Project Benefits

This project will allow for the treatment of produced waters with large total dissolved liquids that could not normally be treated using traditional membrane processes in an environmentally sustainable manner.
