Scope: Measurement of gas oil ratio (GOR)
The purpose of the Single Stage Separator apparatus is to flash pressurized liquids and measure the gas-oil ratio at equilibrium conditions. The liberated gas is measured with the gasometer at ambient conditions while the dead oil flashed is determined by gravity technique.
Live oil from fluid vessel enters the separator. Velocity of fluid decreases because of expansion in cross section. Two phases have enough time to separate. Because of different specific gravity of oil and gas, oil settles down and gas goes to the top ofthe separator chamber.
