Gas/liquid separators, also known as centrifugal or vortex separators, are indispensable in the natural gas manufacturing process. Their simple and efficient design enables the separation of entrained droplets and particles >10 microns with 99% efficiency, requiring no maintenance.

Throughout the journey from extraction to customer consumption, natural gas undergoes pressure and temperature changes, causing water and impurities to precipitate from the stream. Pipeline characteristics and environmental factors further contribute to these variations.

Here are fourteen applications showcasing the use of maintenance-free centrifugal gas/liquid separators in natural gas processing:

 

1. Wellhead Separation: Removing contaminants from raw natural gas at wellheads ensures gas quality meets transportation and processing standards.

2. Pipeline Transmission: Preventing liquid carryover from gas streams in transmission pipelines safeguards downstream equipment and reduces the risk of hydrate formation.

3. Gas Compression Stations: Protecting compressors from liquid carryover at gas compression stations ensures equipment longevity and efficiency.

4. Gas Processing Plants: Gas/liquid separators play a crucial role in ensuring processed gas is free from liquid contaminants, improving overall gas quality.

5. Amine Treating Units: Separators remove excess solvents and liquid hydrocarbons during the gas sweetening process, enhancing gas purity.

6. Condensate Stabilization Units: Separating condensed hydrocarbons allows for the collection of valuable natural gas liquids (NGLs) for various industrial applications.

7. Liquefied Natural Gas (LNG) Plants: Gas/liquid separators remove impurities during the liquefaction process, maintaining product purity.

8. Fractionation Towers: Essential in refining NGL mixtures, separators prevent liquid carryover between stages, ensuring product purity.

9. Gas Storage Facilities: Separators eliminate water vapor accumulation in gas storage facilities, maintaining gas quality over time.

10. Regulator and Metering Stations: Ensuring gas entering these stations is free from liquid contaminants improves accuracy and protects equipment.

11. Fuel Gas Systems: Gas/liquid separators safeguard process equipment from impurities during gas transfer to various industrial applications.

12. Well Testing: Protecting equipment during well testing operations improves accuracy and prolongs equipment lifespan.

13. Offshore Platforms: Separator designs without internal vanes and demisting pads benefit offshore platforms, minimizing maintenance needs.

14. Environmental Control: Gas/liquid separators reduce environmental pollution by removing entrained droplets during natural gas flaring.

 

Changes in pressure and temperature necessitate the use of gas/liquid separators throughout the natural gas processing journey. These separators are also applicable in compressed air, steam, and other compressed gaseous systems. Materials of construction include steel, 304SS, 316SS, Duplex SS, Alloy 20, Hastelloy-C, and Titanium.
