<p>A method and system for treating an aqueous stream in the production of hydrocarbon are provided. An osmotic operation is performed between the stream of produced water and a stream of draw fluid to transfer water from the produced water to the draw fluid, thereby diluting the draw fluid to form a stream of diluted draw fluid and concentrating the produced water to form a stream of concentrated produced water. The concentration of the produced water can facilitate the subsequent removal of contaminants therefrom, and, in some cases, the diluted draw fluid can be re-used, e.g., for injection into the well of the hydrocarbon production operation or as a fertilizing fluid.</p> |
