30L Style Vertical Gas Liquid Separators
Gas liquid separators for vertical upflow applications
The Wright-Austin 30L series of in-line vertical gas/liquid separators remove 99% of droplets and particles ≥10 microns in a very compact design. Moisture-laden gas enters the separator and encounters curved, stationary blading that creates a powerful vortex, propelling droplets to the outer wall. Liquid coalesces and exits through the drain.
There are no moving parts. The design is self-cleaning and requires no maintenance. A patented Vortex Containment Plate (VCP) combined with centrifugal action maximizes separation and minimizes re-entrainment. No complex baffles or flow-obstructing structures are used, resulting in very low pressure drop compared with vane-style designs.
No Minimum Velocity Required
Wright-Austin separators have no minimum velocity requirement. At or near maximum capacity, centrifugal force is the primary separation mechanism. At reduced flow rates, expansion/gravity, agglomeration, and directional change dominate:
- Expansion / Gravity — Gas expands after the inlet nozzle, slowing velocity. Liquid droplets collide, form larger drops, and fall out due to gravity.
- Agglomeration — Droplets forming on interior surfaces attract more droplets; larger drops fall and drain.
- Change in Direction — Flow direction changes to reach the outlet nozzle, shearing off droplets that cannot make the turn.
All Model 30L series separators are available with ASME Section VIII, Division 1 code stamp and CRN.
