separators are used in high GOR applications to remove a high
percentage of free gas from the production fluid. Gas is vented to the
annulus prior to entering the pump, thereby preventing gas lock,
cycling and pump cavitations. This also provides a
stable motor load,
increased production and extended run life.
gas separator uses centrifugal force to separate the free gas from
liquids. The gas/fluid mixture enters the intake ports and moves to the
screw type inducer. Here the pressure of the fluid is increased and
moved to the centrifuge where the separation occurs. The liquids are
forced to the outside of the separator and on to the first pump stage.
The lighter gas rises through the flow divider and is vented to the
GOR applications, a reverse flow separator or standard ported intake
section are available.
efficiencies realized vary greatly from application to application due
to many variables that affect efficient separation such as: annular
intake volume, bubble size, flow rate and gas/liquid ratios etc.
However, stable pumping of fluids with gas/liquid ratios of 60% can be
achieved in the right conditions.
