Separation systems usually present few problems if the feed flow to the plant is stable. However, if feed flow is unstable during normal operation or during well start-up, inefficient separation can result.
Unstable oil export is particularly evident when oil or condensate export volumes reduce to below the minimum flow protection requirements for booster and export pumps. This frequently results in pump instability, inefficient operation and metering mis-measurements. It is also common for Operations to have problems with proving of the metering streams.
