It is often necessary to separate two immiscible liquids, the light and heavy phase, and vapor. In other words, a removal of the total liquid from the gas and also removal of the free water from the hydrocarbon liquid.

The separator may be fitted with a deflector plate, coalescing plates, a foam breaker, a weir plate, and a mist extractor. These components reduce the risk of carry over (liquid in gas line) and carry under ( gas in liquid line) that would affect the flow rate measurement accuracy. Large separator vessels may be fitted with an inlet demisting cyclones instead of deflectors, coalescing plates and a foam breaker.
Design of inlet device is so important to have good gas and liquid distribution, decrease the liquid content entrained in the gas and create larger water in oil and oil in water droplets.

The liquid separation section is usually a variation of a device to provide interface level control, which may include a boot or a weir. The bucket -and- weir type design is used when interface level control may be difficult, such as with heavy oils or when large amounts of an emulsion or paraffin are present.

Fields where a large amount of sand is being produced, separator can be equipped with a sand jet lines. This will allow solid particles that have settled in the separator to temporarily being fluidized by the injection water and the slurry simoultaneously being drained off.

For more than 10 years, Fasam separators have been advancing the concepts, engineering and manufacturing separators that emphasize complete customer satisfaction. With their combination of removal efficiency, maintenance free design, and durability, Fasam's separators remain a paragon for gas, oil, and water separation technology.
