✓ High separation efficiency with vane-pack internals
Oil & Gas Separators (Two-Phase / Three-Phase)
CGOT’s flagship product family: horizontal and vertical two-phase and three-phase separators, metering separators, cyclone, filter and high-efficiency vane separators, in single-vessel or skid-mounted execution. Processing capacity from 10,000 to 500,000 m³/d, design pressure 0.1–15 MPa, in carbon, stainless or duplex steel.
Working Principle
Multi-stage separation using centrifugal force, inertial impact and gravity settling. In three-phase units the density difference of oil, gas and water plus overflow-weir level control delivers clean separation of all three phases.
- Primary separation: the inlet diverter abruptly redirects the flow; large droplets settle by inertial impact while gas carries fines onward.
- Settling section: oil and water stratify by gravity, forming a stable oil–water interface; oil floats, water sinks.
- Deep purification: a vane-pack mist eliminator captures micron-scale droplets; oil and water discharge through independently controlled overflow weirs.
Application Scenarios
- Oilfield production: crude dehydration and oil–gas–water three-phase separation, including heavy-oil and high water-cut fields (e.g. Shengli Oilfield service).
- Natural gas treatment: removal of liquid hydrocarbons and free water to pipeline gas-quality specifications.
- Gathering stations: integrated processing of wellhead streams, optimising field gathering and transport systems.
- Well testing: metering separators measure single-well oil, gas and water rates with built-in P/T compensation.

Frequently Asked Questions
Can separators be customised for offshore FPSO service?
Yes. Skid-mounted separators are engineered for space-constrained, highly corrosive offshore environments, including FPSO units, with materials and layouts adapted to marine service.
What does full-parameter customisation cover?
Separator type (horizontal/vertical, two/three-phase), capacity (10,000–500,000 m³/d), materials (carbon/stainless/duplex steel) and working pressure (0.1–15 MPa), plus controls and instrumentation integrated on a single skid.
