The 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.
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.
