Wright-Austin TF Gas Liquid Separators

Coalescing separators for fine mist removal

Fine mist separators differ from standard centrifugal separators by adding a secondary stage to remove finer droplets. Wright-Austin Type TF coalescing gas-liquid separators use a two-stage design capable of removing 99.7% of entrained droplets and particles >0.30 microns.

How the Two-Stage Design Works

Moisture- and particle-laden gas enters the separator and is deflected into a downward centrifugal pattern. Droplets and particles larger than 10 microns are separated by velocity reduction and momentum, impact the vessel wall, and coalesce. Separated liquid is trapped in a reservoir by the patented Vortex Containment Plate (VCP), which prevents re-entrainment. No expensive or delicate internal baffles are required.

The clean, dry flow then enters the secondary (upper) stage and passes through precision filter cartridges that retain droplets and particles >0.30 microns. Filter elements are epoxy-saturated borosilicate microglass fibers with a glass-matrix drain layer and are available in several retention sizes.

Fine mist separators require periodic filter cartridge replacement and therefore use a hinged cover for access.

The 31-LSF style has a horizontally oriented body and is used when inlet and outlet nozzles are tangential. Choice between Type TF and 31-LSF is usually driven by available space and piping orientation. Both designs use the same filter elements.

Standard ports are provided for vents, gauges and drains; additional connections can be added. Units are available for pipelines up to 16" and can be fabricated from carbon steel, stainless steel or other alloys. Constructed to ASME Section VIII, Division 1. ASME U stamp and CRN registration are available.
