Free Water Knock Outs

Free Water Knockouts (FWKOs) are essential pieces of surface process equipment used in oil and gas operations to remove free water from multiphase production streams. Installed early in the production process, FWKOs use gravity separation to reduce water content before fluids are routed to downstream equipment such as separators, treaters, compressors, and pipelines.

By removing free water at the wellhead or within gathering and midstream systems, Free Water Knockouts help minimize corrosion, erosion, and operational issues while improving overall system efficiency. FWKOs are commonly used in upstream and midstream applications where reliable, low-maintenance water separation is required.

This category includes a range of Free Water Knockouts available in various sizes, pressure ratings, and conditions, including new surplus and used units. Both non-code and ASME code-stamped vessels may be available depending on inventory. Each FWKO is suited for field service and can be integrated into existing oil and gas production or midstream systems.
