System for enabling a supply of water salinity controlled for enhanced oil recovery

摘要

Summary: "invention patent system to enable a supply of water salinity controlled for enhanced oil recovery.The present invention relates to a method for supply water of salinity controlled for enhanced oil recovery to begin raising the pressure and then divide a supply of sea water treated (11) in two flows of food (21) (41) which are then Processed in parallel.A flow of supply is passed through a system of nanofiltration membrane (23) while the other is passed through a system of reverse osmosis membrane (43). The flow of permeate are then combined to a factor of the global recovery in a range from 50% to 65%.The pressure of the first flow of supply (21) is preferably reduced before treatment, and the system of nanofiltration membrane (23) can be installed in a pressure vessel rated for use with a system of reverse osmosis membrane (43).It can be recovered energy from the flow of tailings of nanofiltration (27) or a flow of the waste reverse osmosis (47) and used to reduce the power of good beamento feeding or to provide a pressure increase in terestu00e1gio. The simple power of sea water pump and piping arrangement allows a simplified.
