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.

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.

Horizontal Separator / Vertical Separator

According to the installation mode, the separator can be divided into horizontal/vertical installation, or indoor/outdoor installation.

The horizontal separator is built horizontally, in other words, as the vessel shell axis parallel to the ground. It is usually used for large liquid/gas ratio fluid treatment or liquid/liquid separation. Compared with vertical separators, there are longer horizontal sections for liquid flowing and shorter vertical sections for gravity separation of liquids with different densities. The horizontal separator requires a relatively large horizontal installation space, and its application is generally not affected by the field wind. Horizontal separator can be used for test separator, production separator, two-phase separator, three-phase separator and special application separator.

The vertical separator is built vertically, which means the vessel shell axis is perpendicular to the ground. It is usually used for large gas/liquid ratio fluid treatment. Compared with horizontal separators, there are larger cross-sectional area for gas flowing and longer vertical sections for gravity separation of liquids from the gas. The vertical separator requires a relatively small horizontal installation space, but for very high or slender separator the field wind shall be considered.

Vertical separator can be used for test separator, production separator, two-phase separator, three-phase separator and special application separator.
