A gas/oil separation system for monitoring the performance of a compact, gas/oil separator apparatus which utilizes at least one pair of centrifugal force primary and secondary separators for separating a wellhead fluid containing crude oil, produced water, and hydrocarbon gas from a hydrocarbon production system into its gas and liquid parts employs relatively simple differential pressure instrumentation for producing real-time signals representative of the compact, gas/oil separator apparatus' liquid carryover performance.

[ I claim:] [1.] A gas/oil separation system for monitoring and controlling the performance of a compact, gas/oil separator apparatus which utilizes at least one pair of centrifugal force primary and secondary separators for separating a wellhead fluid containing crude oil, produced water, and hydrocarbon gas from a hydrocarbon production system into its gas and liquid parts by producing real-time signals representative of the compact, gas/oil separator apparatus' liquid carryover performance, comprising:a vessel having a wellhead fluid inlet for entry of a wellhead fluid, a gas export outlet for exit of export gas separated from the wellhead fluid, and an oil/liquid export outlet for exit of oil/liquid separated from the wellhead fluid;a primary centrifugal separator in the vessel for separating a majority of the oil/liquid phase from the wellhead fluid to leave a wet gas phase;a secondary centrifugal separator having an inlet region with a plurality of tangential inlet vanes into which the wet gas phase passes, spaced above and axially aligned with the primary centrifugal separator by an open interstage region, for receiving the wet gas phase and further separating oil/liquid from the wet gas phase to leave a dry gas phase, the secondary centrifugal separator including skimmer means defining skimmer slots above the inlet vanes for receiving the dry gas phase and for channeling the further separated oil/liquid downwardly into the vessel, the skimmer means having an open upper end communicating with the gas export outlet for passing the dry gas phase to the gas export outlet;means for producing a first differential pressure measurement .DELTA.P.sub.1 across the inlet region of the secondary cyclone centrifugal separator;means for producing a second differential pressure measurement .DELTA.P.sub.2 across the overall secondary cyclone centrifugal separator; andmeans for processing the first and second differential pressure measurements .DELTA.P.sub.1 and .DELTA.P.sub.2 and producing signals indicative of .DELTA.P.sub.1 and .DELTA.P.sub.2 for viewing by an operator.
