Oilfield brine utilization for mineral recovery and CO2 capture: A preliminary study on Montney flowback and produced water from Western Canada
A flowchart showing stepwise treatment of high salinity brine by increasing pH (through the addition of caustic soda) to precipitate Mg(OH)2 for separation, then followed by the precipitation of Ca(OH)2 to form a slurry into which CO2 is subsequently injected to produce calcite to capture the gas and solidify the aqu...
