Overview of Oil Gas Separators
An oil and gas separator is a vertical or horizontal pressure vessel commonly used for separating fluids extracted from a well into liquid and gaseous phases.The separators can be installed in either an onshore processing facility or on an offshore platform.Separator engineering comprises of vessel selection, design, customization, and other activities. The separator is also known as a knockout vessel, trap, degasser, scrubber, and stage separator. Based on their functions, it can be of many types such as a well test separator, coalescing filter separator, and more. It is usually manufactured as a two-phase or three-phase separator.
The oil and gas separator is a device that separates the crude oil produced by the oil well from the associated natural gas. The oil and gas separator is placed between the submersible centrifugal pump and the protector to separate the free gas in the well fluid from the well fluid, the liquid is sent to the submersible centrifugal pump, and the gas is released into the annular space of the tubing and casing.
The separators can be installed in either an onshore processing facility or on an offshore platform. Separators are also used in numerous applications including gasoline facilities, upstream and downstream of compressors, and liquid traps in gas transmission lines. They can also be found on dehydration unit intakes, gas sweetening units, and various other types of desiccant-filled equipment.
Features of Oil Gas Separators
1. Primary separation section or device.
2. Secondary or gravity settling section.
3. A mist extraction device to separate liquid droplets from the gas.
4. A gas outlet.
5. A liquid separating segment to separate vapour or gas from oil as well as to remove water from oil when required.
6. Oil outlet.
7. Water outlet in a three-phase unit
Oil Gas Separators Types
Oil and Gas separators are classified as two-phase and three-phase separators.
1. Two-phase separators handle oil and gas
Two stage separators, also known as double effect vessels, use two separators connected in series. The first vessel separates the liquid from the vapors coming from the previous vessel, and these liquids are used to strip the second stage. These types of vessels have a separate vapor line at a higher elevation than that of a single-stage unit to provide an area for the purge vapors.
2. Three-phase separators handle oil, gas, and water
Three-phase separators use a rapid vertical stripping action to recover the gas components from a complex mixture of gases, vapors, liquids, and solids. The three-phase separator consists of two vertically arranged chambers separated by an annular area, in which are mounted radial vanes.
A high velocity stream of steam is passed through the radial vanes for jet entrainment in the chamber below. Stripped crude oil collects in the lower chamber, while gas enters through open slots in the upper chamber.
This type of separator is best used in conjunction with a vessel that contains only gas or only liquid, so that the 3-phase separator can fully separate all three fluids. When this type of vessel is connected between two 2-phase vessels, it typically serves as an oil/water/solids separation device, with little stripping occurring at high velocities.
Applications of Oil Gas Separators
Oil Gas Separators are used to separate the elements that flow into them. As the gas, oil, and water enter the separator, they hit an inlet diverter and begin to separate. Because these elements have different specific gravities, the separation process will continue at a gradual pace as long as they sit in the vessel.

Free Water Knockout (FWKO)
Free water knockout(FWKO) vessels are horizontal or vertical vessels designed to separate liquids of different densities (typically oil and water). They can only be used on streams where the fluids exists separable and not as emulsion. FWKO vessels are used in conjunction with other equipment in order to achieve desirable results.
The degree of separation achieved depends on：
