The Apex Vertical Separator is engineered for high-performance separation of liquids from produced gas, particularly suited for wells with low to moderate liquid content. Its compact and lightweight design makes it ideal for operations where space, mobility, and efficiency are key. Capable of handling gas flow rates up to 125 MMSCFD, the unit delivers exceptional performance through a precision-engineered tangential inlet nozzle, generating centrifugal force that separates heavier liquid particles from the gas stream. Liquids are efficiently directed to a stilled chamber at the base of the vessel, ensuring up to 99% removal of droplets larger than 10 microns.

Designed as a fully modular, self-contained unit, the Apex Vertical Separator comes equipped with:

This system not only enhances separation efficiency but also reduces the risk of liquid carryover to the gas flare and blow-by to surge tanks—supporting safer, cleaner, and more reliable well testing operations.

Applications:

Key Features Include:

Note:Equipment is designed/certified to ASME VIII Div-1 (U Stamp), NACE MR-01-75, DNV 2.7-1/2.7-3, CE / PED, NORSOK standards as applicable based on the region (local) requirements.Other sizes and configurations are available to meet most applications.
