In a vertical three-phase separator, also known as a vertical High Pressure Production Trap (HPPT), flow enters the vessel thru a side inlet, and is immediately met by an inlet diverter. This impact begins the separation process. A downcomer transmits the liquid through the Oil-Gas interface. A chimney equalizes gas pressure between the lower section and the gas section. The “spreader,” or downcomer outlet, is located at the Oil-Water interface. As the Oil rises from this point, any free Water separates out from the Oil phase. The Water droplets flow down through the Oil. As the water flows downward, Oil droplets trapped in the Water phase rise up through the Water flow.
