Two Phase Vertical Separators Sizing

In vertical separators, a minimum diameter must be maintained to allow liquid drops to separate from the vertically moving gas. The liquid retention time requirement specifies a combination of diameter and liquid volume height. Any diameter greater than the minimum … Continue reading

Two Phase Separator Re-entrainment

Re-entrainment is a phenomenon caused by high gas velocity at the gas-liquid interface of a separator. Momentum transfer from the gas to the liquid causes waves and ripples in the liquid, and then droplets are broken away from the liquid … Continue reading

Two Phase Separator Drop Size

The purpose of the gas separation section of the vessel is to condition the gas for final polishing by the mist extractor. From field experience it appears that if 100-micron drops are removed in this section, the mist extractor will … Continue reading

Two Phase Separator Settling

In the gravity settling section the liquid drops will settle at a velocity determined by equating the gravity force on the drop with the drag force caused by its motion relative to the gas continuous phase. The drag force is … Continue reading

Horizontal Three Phase Separator Part 2

Figure 5-3 shows an alternate configuration known as a “bucket and weir” design. This design eliminates the need for a liquid interface controller. Both the oil and water flow over weirs where level control is accomplished by a simple displacer … Continue reading

Two Phase vs Three Phase Separator

In our example process the high- and intermediate-stage separators are two-phase, while the low-pressure separator is three-phase. This is calleda “free water knockout” (FWKO) because it is designed to separate the free water from the oil and emulsion, as well … Continue reading

Two Phase Oil and Gas Separator

Produced wellhead fluids are complex mixtures of different compounds of hydrogen and carbon, all with different densities, vapor pressures, and other physical characteristics. As a well stream flows from the hot, high-pressure petroleum reservoir, it experiences pressure and temperature reductions. Gases evolve from the liquids and the well streamchanges in character.
