Separator:- A machine that separates something into its constituent or distinct elements.

Low-pressure separators are necessary for the effective separation of lighter components in the liquid phase and making sure the water is made as pure as possible to be environmentally friendly.

Three phase separator are used in the segregation of the three phases of the inlet stream namely oil gas and water. An inlet deflector is used to lessen the inlet stream momentum and aid in the separation of gas from the liquid phase quickly.there are two perforated buffles or wave breakers to nullify the possibility of the creating waves in the vessel. this helps in making sure that the gas distribution is uniform and the liquid separation is efficient. The presence of weir plates make sure that the levels of oil and gas is maintained such that the liquid gets separated and drawn at the respective sumps by the respective control valves. The mist extractor is placed at the outlet gas nozzle to coalesce define droplets interspersed in the gas and gets and trained in the liquid phase of the separator. An inlet deflector can be in the form of a deflector baffle ,cyclone, inlet wave breakers deforming plates and vane type inlet device for high momentum. The weir plates are placed at the bottom of vessel with the perforated baffles placed at optimum distances to ensure maximum separation occurs in the quickest time. the outlet mist extractor can be in the form of wire mesh for vane type ministers and are also available in cyclones. The separators are available in horizontal and vertical vessels configuration where the horizontal three phase separator is ideal for gas handling needing more space and easier to service while the vertical three phase separator is ideal for solids handling needs less space and harder to service.
