Mist Extractors Used in Oil and Gas Separators
Vane-type mist extractors are widely used in oil and gas separators to remove the liquid mist from the gas. Technical Data used in the field explained in oil and gas courses in Islamabad. These mist extractors can be of many designs. One design is shown in Fig. 12.14B. An enlargement of the mist extractor is . This is a simple but effective mist extractor, consisting of four layers of steel angles placed parallel to each other with the apex of the angle pointing upward. The angles are spaced % in. apart horizontally; that is, they have a S-in. gap between the legs of the angles in the horizontal plane. There is also a %-in. space between the apex of the angle and the leg of the angles in the row above. Some more details of oil and gas courses in Islamabad are as under.
Gas flowing through the mist extractor follows the path illustrated in Fig. 12.14A. This flow pattern takes advantage of impingement, change of flow direction, change of flow velocity, and coalescence to separate liquid mist from the gas. Literally thousands of these mist extractors have been used, with all of them giving good performance. They are inexpensive to manufacture and usually will not plug or foul with foreign material and paraffin. Another design of a vane-type mist extractor is As the gas enters the mist extractor, it is divided into many vertical ribbons (A). Each ribbon of gas is subjected to multiple changes of direction of flow as it flows through the mist extractor. This causes mild turbulence and causes the gas to roll against the vanes, as at (C). The entrained droplets of liquid impinge against the vanes, where they adhere and coalesce (D). The liquid droplets move into the vane pockets (E). The liquid flows downward in these channels to the bottom of the mist extractor and then through the drain to the liquid reservoir in the bottom of the vessel where it can be drained from the separator. 2 The liquid drainage from this mist extractor occurs with the liquid out of the gas stream and with the movement of the liquid flow at a right angle to the direction of flow of the gas.
