Separator Jetting – Key Items and Technical Paper References (B-FSM-132)
This is the last post pertaining to Facilities Sand Management training module M7 on Separator Jetting. Next I will start on module M8 on Sand Cleaning.
Production separators require solids removal (pre or in-situ)
Standard Jetting System
- Jet spacing formula and F-factor
- Balance spray pressure, water usage, and wear
- Sand caps effective for outlet
- Control discharge using gamma densitometer
Cyclonic Jetting System
- Based on hydrocyclone principles
- Provides shielded vortex sand removal
- Single row for small diameter and double row (angled units) for large diameter
- Fixed pressure, flow, and design
Critical to automate jetting system – or don’t install it!
Slurry Transport, Dewatering, and Disposal key part of system
