Separator Jetting – Comparison Between Traditional and Cyclonic Design (B-FSM-127)

Note: I recommend you read through post B-FSM-121 regarding troubleshooting of traditional jetting system design before proceeding through the comparison below.

Cyclonic Jetting System (compared to traditional jetting)

  • Less water use
  • Less erosion on vessel wall
  • Less prone to blockage (cyclonic jet suction larger diameter than sand pan slots)
  • Shielded vortex spray pattern – will not create mixing at oil-water interface even when sand not present
  • Does not require bottom discharge from vessel
  • Standardized system design and layout allows for easier installation and design of control system
  • Both types of systems have similar control system set up and use
  • Both types of systems can experience issues with solids consolidation or slurry constipation if the discharge piping is not designed properly

Automating the jetting system will take care of most issues.

Next week I will start the discussion on slurry transport and handling from jetting systems.
