Description

In a horizontal three-phase separator, also known as a horizontal High Pressure Production Trap (HPPT), fluid enters the vessel through an inlet, and immediately hits an inlet diverter. This sudden impact provides the initial separation of liquid and vapor and begins the Gas-Oil separation process. In the liquid collection section of the vessel, the Oil and and emulsion separate, forming a layer (or “pad”) above the free Water. A weir maintains the Oil level, while an interface liquid level controller maintains the Water level. The Oil spills over the top of the weir, and then a level controller, which operates the oil dump valve, controls its level. An interface level controller also senses the height of the Oil-Water interface. This controller signals another dump valve to release as much Water from the vessel as is needed to maintain the Oil-Water interface at the pre-determined height. Meanwhile, Gas rises to the top of the separator. It flows horizontally and exits thru a mist extractor to a pressure control valve, which maintains constant vessel pressure.
