Bitumen produced from Steam-Assisted Gravity Drainage(SAGD) and Expanding Solvent Steam-Assisted Gravity Drainage(ES-SAGD) processes contains highly viscous emulsions with finely dispersed water droplets and suspended solids, resulting in poor oil–water separation performance. Conventional separation technologies, including Free Water Knockout(FWKO) vessels and Electrostatic Oil Treaters, have limitations in removing fine water droplets and suppressing rag-layer formation under high-viscosity conditions. To address these limitations, this study proposes a hybrid oil–water separation system integrating Electric Grid-based electrostatic coalescence with Microbubble-assisted flotation. The proposed system combines emulsion destabilization by microbubbles with electrostatic droplet coalescence to enhance gravitational separation. An engineering design framework, including operating conditions, electric-field configuration, and microbubble injection strategy, was established for application to ES-SAGD production facilities. To provide quantitative engineering validation, a theoretical analysis based on Stokes' law was performed. Under the assumed design conditions, doubling the water-droplet diameter increased the calculated settling velocity by four times, while reducing the microbubble diameter from 300 to 100 decreased the theoretical rising velocity to approximately one-ninth. These results support the engineering feasibility of the proposed hybrid separation mechanism. The proposed system provides a theoretical engineering design basis for pilot-scale implementation and offers a technical foundation for future experimental validation and AI-assisted intelligent bitumen separation systems.
