Liquid mist can be effectively removed from
the gas stream in an oil and gas separator by a well-designed mist extractor.
Condensable vapors in the gas cannot be removed by mist extractors.
Condensation of these vapors, caused by reduction of temperature, may occur
after the gas has been discharged from the separator. Technical Data used in
the field explained in oil and gas courses in Islamabad.
Thus, existence of liquid in the effluent gas
from an oil and gas separator in many instances may not necessarily reflect the
efficiency of the separator. Because condensable vapors may have the
characteristics of natural gas at separator temperature and pressure,
condensation of these vapors may occur immediately after being discharged from
the separator.
Density difference of liquid and gas may
accomplish separation of liquid droplets from a gas stream where the velocity
of the stream is slow enough and sufficient time is allowed to accomplish
separation. Limiting the gas velocity in a separator may obtain
satisfactory separation without a mist extractor. Some more details of oil and gas courses in
Islamabad are as under.
However, mist extractors are generally
installed in conventional oil and gas separators
to assist in separation and to minimize the
amount of liquid (mist) carried out with the gas. The methods used to remove
oil from gas in oil and gas separators are density difference (gravity
separation), impingement, change of flow direction, change of flow
velocity, centrifugal force, coalescence, and
filtering. Mist extractors used in oil and gas separators can be of many
different designs using one or more of these methods.
a vane-type mist extractor, Fig. 12.15 a centrifugal
one, and Fig. 12.16 shows a knitted-wire-mesh (coalescing)-type mist extractor.
