Slop Oil Recovery and Interface Control
Use better phase evidence for recovery and draw-off decisions.
Slop and waste-oil systems receive changing mixtures of hydrocarbon, water, emulsion and solids. Agar ID-200 measurements at selected points can help monitor emulsion build-up, protect the water outlet and support recovery decisions when a fixed drain time is unreliable.
Separate what can be recovered from what must be treated
APPLICATION VIEW
Slop oil may come from tank drains, desalter brine, process upsets, maintenance and contaminated product. An interface detector does not break an emulsion; it shows the local oil-water condition so settling, draw-off, recycling and treatment decisions can use better evidence.
Record the source and expected composition, then allow separation under the approved batch procedure.
Monitor water-rich, emulsion and hydrocarbon-rich conditions at the chosen elevations.
Inform the control system before free-phase hydrocarbon reaches the effluent route.
Use trends to support decisions to stop transfer, continue settling or route material for treatment.
Four points in the recovery cycle
Engineer the receive, settle, monitor and draw-off sequence around the vessel, outlets and destinations for each phase.
Application engineering
Review stream sources, composition range, vessel geometry, coating, solids, cleaning, temperature, pressure, seals and materials.
Control-system integration
Your questions answered.
Slop-oil recovery and interface-control questions.
Can it quantify recoverable oil in the whole tank?
It measures local concentration at the selected point. Inventory or full-tank composition needs a broader measurement and sampling strategy.
Does it replace sampling?
Not automatically. Online measurement and sampling can serve different purposes.
Can it monitor an emulsion?
It can measure hydrocarbon/water concentration at selected points in a changing transition.
Is one arrangement suitable everywhere?
No. Geometry, composition, connections, process conditions and objectives determine the design.
