  • Patent number: 9713780
    Abstract: A compact rotating separator apparatus to which a fluid stream containing gas, two liquids of different density, and solids is supplied via nozzles or exhaust from a process component; and which employs high centrifugal forces to produce pure streams of the gas, each of the liquids, and a waste stream containing the solids. The energy in the fluid stream is converted to shaft power in the rotating separator apparatus and can be used to generate power. Oil, gas, water and solids from a production well can be directly separated into the constituent streams while producing useful power.
