01 // Application Scope
What a Three-Phase Separator Handles
Three-phase separation is used where a mixed production stream must be separated into gas, hydrocarbon liquid and produced water. Sand-handling provisions can be considered where the incoming fluid contains solids.

Oil + Gas + Water

Production Separation Oilfield production separation according to operating conditions.
Gathering & Treatment Separation before downstream gathering or treatment processes.
Well Testing Separation and measurement where a test or metering configuration is required.
02 // Separation Principle
How Three-Phase Separation Works
The internal arrangement is selected to control the incoming stream, provide sufficient separation time and manage gas, oil and water discharge under the specified operating conditions.
-
01 / Initial Separation
The inlet arrangement reduces incoming momentum and begins separating free gas from the mixed stream.
-
02 / Gravity & Coalescence
Density difference, available residence time and selected internals support oil-water separation.
-
03 / Liquid Collection
Separated oil and water are collected in their designated liquid sections for controlled discharge.
-
04 / Mist Removal
A selected demisting arrangement helps reduce liquid droplets carried with the gas stream.
-
05 / Level & Pressure Control
Level, interface and pressure instruments can be integrated to maintain the required operating condition.
-
06 / Safety & Solids Management
Safety instrumentation, drains and sand-removal provisions are configured according to the project scope.
03 // Internal Arrangement
Inside the Separator
Internal components are selected by fluid characteristics, flow pattern, separation target, control requirements and maintenance needs. The items below are available by configuration rather than fixed on every separator.
01 / Inlet Device
Cyclonic or other inlet arrangements can be selected to begin phase separation and control inlet momentum.
02 / TP / Coalescing Plates
Plate internals can increase effective separation area and support oil-water droplet coalescence.
03 / Mesh Demister
A wire-mesh or selected mist eliminator can reduce liquid carryover from the gas section.
04 / Oil & Water Sections
Separated liquid phases are collected in designated sections before controlled outlet discharge.
05 / Interface & Level Control
Oil-water interface and liquid-level control can be combined with local or remote instrumentation.
06 / Sand Removal
Sand collection, drain and discharge provisions can be integrated for solids-bearing production fluids.
04 // Configurations & Options
One Product Family, Different Project Configurations
Separator orientation, internal arrangement, materials, instrumentation and skid scope are selected according to the process and project. Final availability is subject to technical confirmation.
Engineering & Custom Design →Orientation
Horizontal / Vertical
Selected by gas-liquid loading, liquid holdup, plot space, transport and maintenance considerations.
Delivery Format
Standalone / Skid-Mounted
Supply can range from the separator vessel to an integrated package with related components.
Internals
Selected by Separation Duty
Inlet devices, plate internals, demisting and sand-handling arrangements are available by configuration.
Instrumentation
Project-Specific Controls
Pressure, temperature, level, interface, flow and control functions are defined by the agreed project scope.
Materials
Selected by Service
Material selection and corrosion allowance depend on pressure, temperature, fluid composition and corrosion conditions.
Design Status
Subject to Technical Confirmation
Final dimensions, nozzles, internals and performance basis are confirmed during engineering review.

06 // Engineering Optimization
How We Adjust the Separator to the Duty
Separation performance is not defined by one fixed internal component. The design is adjusted as a system according to changing fluid and operating conditions, without assuming one universal configuration or efficiency figure.
Vessel Size & Geometry
Adjusted to gas and liquid loading, required holdup and installation constraints.
Nozzle Arrangement
Inlet and outlet arrangement is coordinated with process flow and package layout.
Retention Time
Liquid residence and effective separation volume are considered against the required duty.
Internal Arrangement
Inlet separation, coalescing, demisting and solids management are selected as needed.
Materials & Corrosion
Material selection and corrosion allowance are reviewed against service conditions.
Instrumentation & Control
Level, interface, pressure and related controls are coordinated with the operating philosophy.
07 // Integrated Delivery
Skid-Mounted Separator System
Where the project requires a packaged system, the separator can be integrated with associated piping, valves, instruments, controls and structural components before shipment.
