TREATMENT OF PRODUCED WATER, PARTICULARLY OBTAINED FROM A CHEMICALLY ENHANCED OIL RECOVERY PROCESS USING VISCOSITY-INCREASING POLYMERS |
摘要 |
The present invention is concerned with the treatment of produced water, that may be obtained from a chemically enhanced oil recovery process using viscosity-increasing polymeric compounds. Said treatment comprises particularly the steps of obtaining a produced water, such as from an oil-water mixture recovered from an oil-bearing formation, wherein the produced water comprises the viscosity-increasing polymeric compounds; and, of directing the produced water to a specific filtration device, and subjecting the produced water to filtration, for obtaining a retentate stream and a permeate stream. Said process allows particularly obtaining a permeate comprising the viscosity-increasing polymeric compounds, said permeate being substantially free of suspended solids, free oil and emulsified oil. |
