AI Technical Summary
Existing chemical demulsifiers have complex preparation processes and are not suitable for large-scale industrial production when treating heavy oil-containing wastewater and acidic oil and gas field wastewater, and the treatment effect is not ideal.
Using nano-alumina as a carrier, a compound with a cage-like structure is loaded as a demulsifier. The demulsifier is prepared by ultrasonic reaction of triethanolamine and polyetheramine in a solvent. The compound has amino, ether, alkyl and other groups, which enhance the oil-water interface separation ability and the interface film rupture effect.
It achieves rapid and efficient oil-water separation, simplifies the preparation process, reduces costs, is suitable for large-scale industrial production, and achieves an oil removal rate of over 90%.
