Application of membrane distillation for the treatment of oil field produced water

Study on the structure–activity relationship of cationic polyacrylates for the treatment of oilfield produced water

“…In general, produced uids from offshore oilelds are treated using three-phase separation, thermal processing, and electric dehydration to obtain anhydrous crude oil, while a large amount of oily wastewater (also referred to as produced water) is generated. [1][2][3][4] The produced water is treated by inclined-plate separation, otation, and walnut shell ltration and is then reinjected into the formation. In order to remove oil more efficiently, a reverse demulsier is added to the three-phase separator to remove large oil droplets from water, 5 and a otation agent is added to the otation separator to remove small oil droplets from water.…”

Fabrication of zinc oxide nanorods for photocatalytic degradation of docosane, a petroleum pollutant, under solar light simulator

“…Global crude oil production is approximately 80 million barrels per day, whereas OPW production is approximately 250 million barrels per day, which raises environmental and economic concerns. 4,5 The volume ratio of the discharge of OPW is not constant and can increase or decrease based on geographical location, the age of the well, and production techniques employed. 6 The characteristics and concentrations of hazardous substances in OPW can vary depending on the condition of oil wells throughout the operation.…”

Efficiency and bacterial diversity of an improved anaerobic baffled reactor for the remediation of wastewater from alkaline-surfactant-polymer (ASP) flooding technology

“…To date, the major physical and chemical methods developed and applied to treat ASP flooding wastewater include membrane distillation [8,9], membrane filtration [10,11], air flotation [12], electrocoagulation [13], and adsorption [14]. However, the high operating and maintenance costs are the shortcomings of these technologies, which have a negative impact on their overall performance and limit the expanded application of these technologies [15].…”
