A well-designed three-phase separator depends on several key factors:
✔ Operating pressure
✔ Operating temperature
✔ Flow rate (capacity)
✔ Fluid properties and composition
✔ Residence time
✔ Vessel sizing (diameter and length)
✔ Oil–water interface control
✔ Internal components
✔ Proper instrumentation and control system (pressure, level, and interface transmitters, PCV, LCV, and dump valves)
Before implementation, Aspen HYSYS can be used to simulate separator performance under different operating scenarios with the Peng Robinson (PR) thermodynamic package, engineers can validate the design, predict phase separation, and optimize operating conditions before field deployment.
