Separator Jetting – Cyclonic Jetting Cluster Layout and Control System (B-FSM-126)
The cyclonic jetting units are assembled into clusters to for standardization of installation and control during operation.
Cluster Design
- Maximum of four-unit heads per cluster
- Cluster has 2” inlet and outlet piping for vessel penetration
- Penetration can be from bottom, side, or top
- Header piping (internal) of stainless steel
- Example of in-line and square cluster shown in header graphic
Control System
- Reference graphic below for descriptions
- Operate one vessel zone at a time (spray jet + discharge). A zone is defined as one cluster (in-line or square).
- Flow control valve (FCV) to set to control vortex spray
- Set outlet (slurry) discharge at same flow rate with FCV
- Density meter (DM) determines when to shut zone isolation valve (recommended when concentration <5 vol.%)
- Cyclonic jetting heads are quite predictable and normally complete cycle in 5-7 minutes
- Critical to automate system for effective performance
Next week I will compare traditional jetting versus cyclonic jetting.
