Coalescence
Coalescing packs afford an effective means of separating an d removing liquid mist from a stream of natural gas. Technical Data used in the field explained in oil and gas courses in Islamabad. One of their most appropriate uses is the removal of liquid mist from gas in transmission and distribution systems where the amount of liquid in the gas is low.
Coalescing packs can be made of Burl saddles, Ranching rings, knitted wire mesh, and other such tower-packing materials. The packs use a combination of impingement, change of direction, change of velocity, and coalescence to separate and to remove liquid mist from gas. These packs provide a large surface area for collection and coalescence of the liquid mist. is a schematic of a knitted wire mesh coalescing pack-type mist extractor used in some oil and gas separators and gas scrubbers. Some more details of oil and gas courses in Islamabad are as under.
A word of caution is appropriate concerning the use of coalescing packs in oil and gas separators for general field use. Coalescing packs may be made of frangible material that can be damaged during transit or installation if they are installed in the separator in the manufacturing shop before shipment to point of use. Knitted wire mesh may foul or plug from paraffin deposition and other foreign material and thus make a separator inoperative after a short period of service. Also, excessive pressure drop across the pack may force the pack out of place and allow channeling around or through the pack.
Even though coalescing packs are very effective in the removal of liquid mist from gas, it is usually preferred to use vane-type mist extractors for most oil and gas separators because they may be used under widely varying field conditions. Because of the “fouling” tendency of coalescing-type mist extractors, their use may appropriately be restricted to gas scrubbers used in gas gathering, transmission, and distribution systems.
