Three-phase Separator

Three-phase Separator

Three-phase separator is a basic component of petroleum production system, which is used to separate reservoir fluid from oil, gas and water. Then these separated flows are transported to the downstream for processing.

In general, a mixed fluid can be considered as a small amount of liquid A or/and gas B dispersed in a large amount of fluid C. In this case, the dispersed liquid A or gas B is called the dispersed phase, while the large continuous fluid C is called the continuous phase. For gas-liquid separation, it is sometimes necessary to remove tiny droplets of liquid A and C from large amount of gas B, where gas B is the continuous phase, and liquid A and C are the dispersed phases. When only one liquid and gas is considered for separation, it is called a two-phase separator or a liquid-gas separator.

The basic principle of separator is gravity separation. By making use of the density difference of different phase states, the droplet can settle or float freely under the combined force of gravity, buoyancy, fluid resistance and intermolecular forces. It has good applicability for both laminar and turbulent flows.

Our three-phase separator adopts advanced technologies of effective separation,throttling,automatic control,comprehensive anti corrosion and skid-mounted structure,and has the characteristics of high separating effeciency,high automation,stability,high measurement precision and accurate data details.
  • In addition, our three-phase separator has the following advantages:
  • 1.Compact and reasonable structure design, integration of a variety of measuring instruments and control equipment;
  • 2.Compatible with multiple control modes (direct + PLC + computer + DCS);
  • 3.Multilevel security measures to ensure safe and reliable operation of the device;
  • 4.In addition to standard products, we can also customize the most suitable design for customers according to their needs;
  • 5.Reliable quality, which can be matched with components according to the customer's designated brand, such as instruments and valves;
  • 6.It can meet GB, ASME, API and other national and industrial specifications at the same time.

Our engineering team can make the most cost-effective design according to the specific requirements of the user. Send us a message/e-mail or consult online for the latest stocks and quotes!

The Three Phase Test separators (3P Test Separator)

The Three Phase Test separators (3P Test Separator) are used in well testing, well clean-ups and other flow operations for efficient and safe separation and efficient measurement of oil, gas and water. 3P Test Separators usually supplied with high-accuracy instruments, control and shut-off valves, piping and skid, and referred as Test Separator Package / Module / Skid. Separator vessel is equipped with internal components, such as inlet deflector, vane pack, coalescer, wave breaker, weir plates, and mist extractor. Separator modular unit can be used both in offshore or onshore, either in standalone item or part of the package, and designed to fit the trailer for ensure fast and effective mobility during operation.

Basic Specification Data

Separator can be designed as per client’s operation conditions depending on flowrate, temperature, pressure, working medium and other operation data. Most of the clients, prefer size of 42 in. x 10 ft. and pressure of 1440 psi,b for well test operation.
