Abstract:
Processes and systems form diluted brine from saturated brine without direct addition of soft or contaminated water in an oil and/or gas treatment facility. Water containing salt contaminants is fed to a forward osmosis membrane. The salt contaminants can be cations, anions, carbonate, bicarbonate and combinations thereof. A saturated brine solution is fed to a draw side of the forward osmosis membrane which allows water to pass from the feed side to the draw side and minimizes the passage of the salt contaminants from the feed side to the draw side. A diluted brine solution having a TDS concentration lower than a TDS concentration of the saturated brine solution is removed from the draw side outlet of the forward osmosis membrane. A concentrated contaminated water stream having a TDS concentration higher than a TDS concentration of the contaminated water feed is removed from the feed side outlet of the forward osmosis membrane.

Claim (Index 1):
A process for forming diluted brine from saturated brine without the direct addition of soft water in an oil and/or gas treatment facility, comprising:\n a. feeding a contaminated water feed comprising water and salt contaminants selected from the group consisting of cations, anions, carbonate, bicarbonate and combinations thereof from a source of contaminated water to a feed side of a forward osmosis membrane; b. feeding a saturated brine solution to a draw side of the forward osmosis membrane wherein the forward osmosis membrane allows water to pass from the feed side to the draw side and the forward osmosis membrane minimizes passage of the salt contaminants from the feed side to the draw side; c. removing a diluted brine solution having a total dissolved solids concentration lower than a total dissolved solids concentration of the saturated brine solution from the draw side outlet of the forward osmosis membrane wherein no soft water or contaminated water is added to the diluted brine solution; and d. removing a concentrated contaminated water stream having a total dissolved solids concentration higher than a total dissolved solids concentration of the contaminated water feed from the feed side outlet of the forward osmosis membrane.
