Separator Jetting – Cyclonic Jetting Unit System Operating Parameters (B-FSM-125)

The following operating and installation parameters are recommended when designing a cyclonic jetting unit for your vessel. Note: these design parameters are specific to the eProcess Technologies eJECT™ technology only and may vary for other suppliers.

Total Affected Area Indicates Amount of Sand Removed

  • Affected area: top area of the influenced ellipse
  • affected diameter: mean value of major and minor ellipse axes (ref. post B-FSM-124).

Installation Guidelines:

  • Spacing: 1.0 meter center-center on eJECT heads
  • Set height (clearance below head): 4” (100 mm)
  • Spray flow/pressure: 11 psid (0.75 bar) / 33 gpm (7.5 m³/hr)
  • Slurry flow/pressure: 7 psid (0.5 bar) / 33 gpm (7.5 m³/hr)
  • Sand depth: The unit can be fully covered
  • Installation angle: Vertical (single row), 15° (double row)
  • Spray source: any compatible water, must remove particles >1.0 mm

Next week I will discuss the cyclonic jetting cluster layout and control system design.
