Gas Liquid Coalescers remove lube oil, mist and fine solid particles from a gas stream

Gas-liquid Coalescer - Type 140

The Winston/Royal Guard Type 140 Gas Liquid Coalescer is the solution for recovering aerosol, mist, and larger size liquid particles from a gas stream. Although primarily designed for liquid removal, extremely fine solids will also be captured. These gas coalescers have applications in natural gas processing, refining, petrochemical, and others. The Type 140 gas liquid coalescer, sometimes referred to as a reverse flow coalescer, or gas coalescer, is typically furnished in a more efficient vertical configuration so as to prevent coalesced liquids from falling onto and flooding a lower cartridge.

 

  • Removes 99.9% of 0.3 micron particle size and larger. Maximum efficiency cartridges of up to 99.98% can be furnished.
  • Recovers lube oil downstream of compressors.
  • Removes liquid and solid contaminants from natural gas to protect compressors, turbines, glycol dehydrators, amine units, ammonia processes, molecular sieves and other catalyst beds, and other downstream equipment.
  • Improves operational processes and reduces maintenance costs.

 

How the gas liquid coalescer works:  Liquid-entrained gas first enters the lower chamber of the coalescer vessel where the heavier liquid particles fall out due to the sudden change in velocity.  The gas then flows into the coalescer cartridges.  The direction of flow is from inside the coalescing cartridge through the media to the outside.  This is the opposite flow direction as that of a standard filter cartridge, resulting in the often used term “reverse flow coalescer”.  As the gas flows through the cartridge media, aerosol and larger entrained liquid particles attach to the media fibers.  As the flow continues, additional liquids attach to the fibers and merge, or coalesce, with other droplets.  This process continues until the droplets have grown large enough to release from the media with the gas flow and exit the cartridge. Here, the droplets encounter a sudden drop in velocity, and as they are too heavy for the gas to lift, fall to the bottom of the vessel housing from gravitational effects.  The exterior drainage layer of the cartridge assists in this process.  The liquid is recovered and clean dry gas exits the coalescer vessel.

 

Our type 140 gas/liquid coalescer is an excellent choice for contaminant protection for gas production, transmission and processing industries.

  • Removes liquid hydrocarbons and other contaminants from natural gas to protect amine contactors from foaming and fouling.
  • Recovers amine carried over from contactors.
  • Removes contaminants from natural gas to protect glycol dehydrator contactors from foaming or corrosion, resulting in poor performance, higher maintenance costs, and high water content.
  • Removes lube oil after compressors in ammonia processing.
  • Recovers lube oil downstream of compressors.
  • Protects low and ultra-low NOx burner tips from contaminant fouling and loss of efficiency.
  • Protects catalyst beds and other purification processes in plants.
  • Removes contaminants in gas injection wells.
  • Removes water and solid contaminants from gas to protect dry desiccant dehydration systems.
