Removal of membrane fouling after polymer flooding produced water treatment

Original language description

Polymer flooding has been successfully applied as an oil exploitation method in oil and gas industry. Partially hydrolyzed polyacrylamide (HPAM) is one of the most common polymers used in polymer flooding1. Along with polymer flooding, there is also an increasing amount of produced water per year, which consists of a complex mixture of chemical additives, HPAM, crude oil, suspended solids, and salts. Polymer flooding produced water can be reused to decrease water demand if appropriately handled. Electrodialysis (ED) has been successfully used to reduce the salinity of the polymer flooding produced water1,2. However, recent articles report that HPAM causes fouling – especially on anion exchange membranes3. Ion exchange membranes (IEMs) received after pilot desalination of polymer flooding produced water were subjected to ex-situ chemical cleaning at 60 °C. The cleaning was realized consequently with acid (0.1M HCl) and base (0.1M NaOH) solution, or acid, base, and sodium dodecylbenzenesulfonate (0.4 wt%) solution. IEMs were characterized to determine the efficiency of the cleaning procedures using optical and scanning electron microscopy, FTIR, evaluation of swelling degree, ion exchange capacity, resistance, and permselectivity. The results demonstrated that the electrochemical properties of IEMs can be improved after the cleaning, however individual results are also strongly dependent on the position of an IEM in the ED stack.
