The most common separator in oil and gas production is the three-phase separator. The three phase separator market provides the vessels that take the full well stream and produce three separate outputs: gas (for sale or fuel), oil (for storage and sale), and water (for disposal or reinjection).

The Three-Phase Separation Process

The [LSI keyword: three phase separator market] relies on careful internal design. The inlet diverter slows the incoming fluid. The gas flows upward, passing through a mist extractor (vane pack or mesh pad) to remove liquid droplets. The oil and water settle in the lower section. An oil-water interface is maintained by a weir or by an interface level controller. The oil (lighter) flows over the oil weir, while the water (heavier) flows under the water weir (or through a separate outlet). The three phase separator market for "horizontal" vessels is the most common, as they have a large settling area. The three phase separator market for "vertical" vessels is used where space is limited (offshore) and when the gas volume is high. The three phase separator market for "internals" (inlet devices, baffles, coalescers, and mist extractors) is a specialized segment. The three phase separator market for "level" control (using displacers or guided wave radar) is critical for maintaining the oil-water interface.

The three phase separator market for "upstream" (wellhead) is the largest. The three phase separator market for "test" separators (smaller units used to measure the flow from individual wells) is also significant. The three phase separator market for "low-temperature" separators (used in gas processing to condense liquids) is a niche.

Materials and Coatings

The three phase separator market uses carbon steel for most applications. The three phase separator market for "stainless steel" is used for corrosive service (high CO2 or H2S). The three phase separator market for "clad" steel (stainless layer on carbon steel) reduces cost. The three phase separator market for "internal" coatings (epoxy or phenolic) prevents corrosion. The three phase separator market for "sand" removal (using desanders or sand jets) is important for wells that produce sand. As the three phase separator market continues to evolve, the focus will be on "compact" designs (using cyclonic technology to reduce size), on "high-pressure" designs (for deepwater), and on "smart" control (using automated valves to maintain interface levels). The three phase separator market is the workhorse of oilfield processing, turning a raw mixture into marketable products.
