Separation of liquids and gases using gas liquid separators is most commonly seen in refining and gas processing applications. Contamination could lead to malfunction of components, which leads to costly downtime and repairs. Downtime associated with contamination is greatly reduced when these sediments are removed from the media. For example, in an amine contractor tower, presence of solid contaminants and hydrocarbons can cause the liquid to foam. This can damage the internal components, reduce operational efficiency, and even cause leaks. Hence, it is important to use inline liquid gas separators that are compatible with your application. You can consult with gas liquid separator suppliers in USA to find the technology that best suits you.
Two Main Reasons for Using Gas Liquid Separators
The primary reasons for use of gas liquid separators are:
- For alteration and/or purity of the final product
- To protect the internal mechanism and components of downstream equipment
5 Main Types of Separators Used for Gas Liquid Separation
Removal of liquids and solids from gas is achieved by using one of the following separation technologies:
- Gravity Separators
These gas liquid separators use gravitational force for separation. The separation process is most efficient when the vessel diameter is large enough to slow the gas velocity significantly.
- Centrifugal Separators
As the name suggests, the main acting force in this type of separator is centrifugal force. Also known as cyclone separators, these devices can remove aerosol with diameters of 8 µm and larger. When combined with a coalescer pad higher efficiencies and smaller diameters of entrainment removal can be obtained.
- Mist Eliminators
These utilize a coalescer pad for primary separation. Like the gravity separators, mist eliminators require a large vessel diameter to function efficiently. Mist eliminators have the ability to remove droplets 1 to and larger.
- Vane Separators
Vane separators inertial impaction as the separation technology. Vane separators can operate at higher velocities as compared to mist eliminators. Filter vane separators can remove droplet sizes that are 10 µm or larger in size. When combined with a coalescer pad higher efficiencies and smaller diameters of entrainment removal can be obtained.
- Baffle Separators
Utilizing inertial impaction, the gas flow is directed at a baffle plate in a vessel. The sharp change in velocity and direction change causes separation. Baffle separators have the ability to remove droplets of sizes ranging from 10 microns and larger.
Liquid/Gas Separator Technologies Used In Combination
These units make use of the best of the technologies mentioned above in combination according to the specific gas flow and the desired removal efficiency. They can work efficiently with high velocity streams. By using a combination of these gas liquid separator technologies there is basically a solution to separating entrainment from all gas streams.
