COMPACT, HIGH-EFFICIENCY, GAS/LIQUID SEPARATOR METHOD AND APPARATUS

摘要

A method and apparatus for separating a wellhead fluid mixture containing oi l and gas phases obtained from hydrocarbon production systems into its constituent parts employs a pressure vessel having an inlet for entry of the wellhead fluids m ixture and an outlet for exit of a separated gas referred to as export gas. A primary cent rifugal separator is provided in the pressure vessel for centrifugally separating a first port ion of the oil from the wellhead fluids mixture to produce a wet gas containing some remaining o il. A second centrifugal separator is also provided in the vessel and performs a second c entrifugal separation operation on the wet gas to remove substantially all of the remai ning oil from the wet gas to produce the export gas which is conveyed out of the pressure vessel. The oil and remaining oil separated from the wellhead fluids mixture is conveyed from the pressure vessel via another outlet.
