2 & 3-Phase Separator Vessels


TransTech  is your source for top quality two- an three-phase separators for separating produced well fluids into gas and liquids (2 phase separator) or gas, oil and water streams (3 phase separator).

Every liquid separation operation is unique and our experienced team of fabrication experts and process engineers brings formidable knowledge of separator operating principals combined with decades of oil and gas processing expertise to every project.  We fabricate each and every separator vessel to meet the exact site attributes, wellstream characteristics, operating demands and budgets of our clients.

Designing the right 2- or 3-phase separator to suit your operations is critical.  Sizing your separator properly and correctly accommodating variables such as retention time, settling of oil droplets and droplet size all influence the performance of your vessel.

Incorrectly sized vessels can promote the formation of emulsions, lead to gas blow-by and liquid carry-over and foster sand or paraffin accumulation.  Our design experts have the know-how to address your particular fluid type and operating conditions and determine the proper vessel design to ensure reliable operations – and the maximum sellable gas and petroleum liquids output.


Our two- and three-phase separators can be designed for vertical or horizontal orientation.  Horizontal separators are generally best at accommodating larger gas volumes, but require more space than vertical separators.  Vertical separators offer a smaller footprint and typically provide preferable liquid surge capacity and solids handling, but are not as easily serviced as horizontal separators.

We’ll work with you to best match separator capabilities to your gas handling requirements and space availability.


Your two- or three-phase separator can be delivered as a bare vessel, mounted to a skid, or can be incorporated into your own custom production skid.

TransTech offers end-to-end delivery of your two or three-phase separator including engineering design, fabrication and test, delivery and installation—within the shortest possible lead times—for seamless project execution and fast start-up.



  • All vessels are fabricated and NDE per the latest addition of ASME SEC. VIII, Div. 1 of Pressure Vessel Code
  • Large in-stock inventory yields short lead times and fast delivery
  • Custom configured to your exact specifications,
  • Top quality manufacturing for long operational life
  • Inlet diverter (deflector baffle, cyclone inlet, and others)
  • Defoaming plates
  • Wave breaker
  • Weir plates
  • Vortex breaker
  • Mist Extractor
  • Liquid outlet and pressure relief valve
  • Instrumentation & controls
  • Vessel insulation
  • Access Manways
  • Flange and blind, hinge options, manual and hydraulic davit lift or spring assists can be added to any manway

All finished two- and three-phase separator vessels are tested and ASME certified, National Board code stamped and registered.


With one of the most extensive inventories of new and used ASME pressure vessels in the country, we’re able to offer a wide range of options for addressing your two-and three-phase separator vessel needs—and tremendous flexibility in addressing your project schedule and budget requirements.

FREE ASME Pressure Vessel Material Analysis - MAWP - Max Allowable Working Pressure Guidance

FREE Preliminary Vessel Material Analysis

Without the right data to optimize your vessel design, it's easy to miscalculate design pressure by overcompensating for MAWP.  This can lead to incorrectly sized vessels and other  issues including unnecessary costs, underperforming assets—and disappointing ROI,

Let our AMSE vessel design experts assist you with a FREE preliminary material analysis!  We'll help you determine the right material grade & thickness for your pressure rating for optimal vessel performance, often leading to:

  • Reduced overall vessel weight—and cost
  • More economical constructability
