Demulsification Performance of Hyper-Branched Dendrimer in ASP Flooding

Abstract:

Owing to the double actions by ternary liquid of ASP flooding and natural emulsifier in oil, the recovery liquid emulsified seriously as well as oil content in water rose after oil-water separation. Demulsification on recovery water in ASP flooding has been discussed via the modified terminal groups of hyperbranched tree macromolecules dendrimers polyamidoamine (PAMAM). Laboratory tests showed that PAE01 demulsifier had good demulsification efficiency. When demulsifier dosage was 120mg/L, sedimentation time was 90min, temperature was 45°C, oil content in water dropped from initial 5000mg/L to 197mg/L after demulsification, the deoiling rate was 96.1%. When initial oil content was 1500mg/L, oil content in water dropped to 215mg/L, the deoiling rate was 85.7%.
