Abstract: Treating oily wastewater from oilfields to meet the water quality standards for injection water or effluent discharge is crucial to preventing environmental pollution incidents. For heavily emulsified oily wastewater, the optimal demulsifier should be selected for demulsification and purification.…
Demulsification refers to the complete breakdown of an emulsion, resulting in two immiscible phases. In the process of oil extraction, changes in formation pressure, temperature, flow rate, and other factors can cause emulsions in crude oil to rupture, leading to…
