Abstract
|
Water
produced from alkaline–surfactant–polymer flooding technology is more difficult
to treat than that from water flooding. Researchers synthesized an innovative
magnetic demulsifier, called M-5010, through the reaction of 5010, a type of
demulsifier currently used in oilfields, and epoxy group functionalized
Fe3O4@SiO2 microspheres.
They studied oil removal rates and the effect of the demulsifier dosage as well as the settling time. They observed the oil removal rate of M-5010 to be higher than that of 5010 under the same conditions. In addition, M-5010 can be recycled and reused by using an external magnetic field that acts as a material phase separator. Accordingly, they observed the M-5010 to still be effective after being reused for 5 cycles. Results indicate that the magnetic demulsifier can be used as an effective and recyclable material for the removal of oil from oil contaminated wastewater. |
