Change of Flow Direction

If a flowing stream of gas containing liquid mist is impinged against a surface, the liquid mist may adhere to and coalesce on the surface. Technical Data used in the field explained in oil and gas courses in Islamabad.   After the mist coalesces into larger droplets, the droplets will gravitate to the liquid section of the vessel. If the liquid content of the gas is high, or if the mist particles are extremely fine, several successive impingement surfaces may be required to effect satisfactory removal of the mist. A mist extractor that provides repeated impingement to remove fine oil mist from the gas

When the direction of flow of a gas stream containing liquid mist is changed abruptly, inertia causes the liquid to continue in the original direction of flow. Separation of liquid mist from the gas thus can be effected because the gas will more readily assume the change of flow direction and will flow away from the liquid mist particles. The liquid thus removed may coalesce on a surface or fall to the liquid section below. The mist extractor uses this method of mist extraction. Some more details of oil and gas courses in Islamabad are as under.

Change of Flow Velocity: Separation of liquid and gas can be effected with either a sudden increase or decrease in gas velocity. Both conditions use the difference in inertia of gas and liquid. With a decrease in velocity, the higher inertia of the liquid mist carries it forward and away from the gas. The liquid may then coalesce on some surface and gravitate to the liquid  section of the separator. With an increase in gas velocity,  the higher inertia of the liquid causes the gas to move away from the liquid, and the liquid may fall to the liquid section of the vessel. one version of a vane-type mist extractor that uses change of flow velocity. This mist extractor is used in the typical vertical oil and gas separator.
