Three phase separator produced by GN solids control is used to separate the oil from water for refinery oil sludge separation project. There are 2 options for the 3 phase separation unit, one is to use three phase decanter centrifuge, the other option is GN standard 3 phase separation package.

Three phase separation package is consist of 2 phase decanter centrifuge and feed by screw pump, buffer tank to receive the discharged fluids and to be transferred by diaphragm pump or slowly flow to disc centrifuge for oil and water separation, the oil is recovered and back to the client, the water will be collected and re-used in the circulation system. By using proper demulsifier, the recovered oil can reach to BS &W below 3%. The water to be collected with oil content 500 ~ 1000ppm.

The 2 phase separation decanter centrifuge with VFD control panel is used to separate the ultra fine solids up to 2 microns. The max speed is 3900rpm and the normal working speed is 3200rpm, the max G force is up to 3063G and typical G force is up to 2062G, if necessary, the used can add proper chemicals to accumulate the ultra fine solids for easier separation by gravity difference. The disc centrifuge can provide high G force to separate the oil from water after discharges by decanter centrifuge.
Another option is oil water separator, the separation result is not as good as disc centrifuge, but the capacity is much bigger and the price is cheaper. The 3 phase separation package can be used for most type of oil sludge waste treatment, like Crude Oil storage tank cleaning sludge, Refinery plant waste oil sludge, Drilling waste oil sludge.
