An oil and gas separator is a device for separating oil, gas and water, which are extracted from wells in the form of an associated oil emulsion. Oil purification and degassing are necessary to improve its quality, reduce transportation costs and ensure safe operation of equipment.

How the oil and gas separator type NGS is designed and works
The oil and gas separator type NGS has a horizontal body with elliptical bottoms, in which internal devices are located: drop eliminators, defoamers, depulsators, etc. These devices help improve separation, reduce oil and gas losses, as well as smooth out pressure and temperature changes.
The operating principle of the NGS oil and gas separator is that the oil emulsion enters the housing through a fitting and a pipe, where under the influence of force gravity and density differences, separation into phases occurs: gas, oil and water. Gas comes out through the top fitting and pipe, oil through the middle, and water through the bottom. Purified oil and gas are sent for further treatment and collection, and water is sent for recycling or reuse.
Classification
NGS oil and gas separators are classified according to different criteria:
- type of construction - horizontal, vertical, spherical, etc.;
- conditional pressure - low, medium, high and ultra-high pressure;
- material - steel, stainless steel, composite and etc.;
- climatic version - tropical, temperate, cold, etc.
Advantages and disadvantages of an oil and gas separator of the NGS type
The oil and gas separator NGS is in demand due to the following advantages:
- high separation efficiency achieved through the optimal choice of internal devices and operating modes;
- simplicity of design and operation, ensuring the reliability and durability of the device;
- the ability to regulate operating parameters: pressure, temperature, flow, etc.;
- a wide range of applications, allowing the separator to be used for various types of oil and gas, as well as for different conditions of production and processing.
However, the oil and gas separator NGS is not without its drawbacks. Firstly, it is large in size, requiring a foundation and anchor bolts to secure the device. Secondly, there are limitations in temperature and pressure. These parameters must not exceed certain values specified in the device passport. Thirdly, there are requirements for oil quality. It should be non-foamy. In simple words, the oil should not contain a large number of gas bubbles, which can impair separation and increase its losses.
