Condensate Stabilizer

Condensate Stabilizers reduce the vapor pressure of produced oil/condensate for stock tank storage and transport, and increase the recoverable quantity of Natural Gas Liquids (NGLs).

The Exterran Production Solutions Condensate Stabilizer Unit is designed to minimize startup time, safely stabilize condensates by reducing Reid Vapor Pressure, (RVP) and efficiently capture Natural Gas Liquids (NGL) in wellstreams.

Key Benefits


  • Safely stabilize condensate liquids with Exterran’s pre-engineered, modular design
  • Efficiently separate and capture valuable NGLs down to 10 RVP or less
  • Proven industry-leading design and construction maximizes production and minimizes downtime


  • Pre-engineered modular design speeds startup
  • Safe startup time and simplify connection with Exterran’s uniform isometric piping
  • Prompt, professional service, support and spare parts from local technicians in or near every major oil & gas producing region in the U.S. and numerous areas around the world

How it Works

After upstream separation, the condensate stream enters the unit. It is first preheated in the inlet heat exchanger and then flows into the upper section of the stabilizer tower. Inside the tower, the light components – typically methane, ethane, propane, and butane – rise and exit the overhead vapor outlet. The heavier liquid components descend and pass through the indirect heater to cause additional vapor to flash off, rise and exit the tower.

Stabilized liquids collect in the bottom of the tower. They are routed to the inlet heat exchanger to cool. Stabilized liquid product then flows to storage tanks.

The vapor that exits the tower flows through an ambient cooler and then to a low-pressure separator. Gas from the separator is routed to compression for delivery to market. NGLs exit the separator and flow to a blowcase where they are pressurized for a bullet tank or pipeline.
