Phase Separator on Oil and Gas Facilities

{0 Comments}

Fluids outputted by the wellhead are made of form many different compounds of hydrocarbon and each compound has its own physical characteristic. The fluids flow from high temperature and high pressure reservoir surface facilities so its temperature and pressure will decrease. Gases from the well stream or evolved in liquid will flow in high speed …

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 required for gas capacity can be chosen. Figure 4-15 shows the model used for a …

Two Phase Separator Re-entrainment

{0 Comments}

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 phase. The general rule of thumb that calls for limiting the slenderness ratio to a …

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 not become flooded and will be able to perform its job of removing those drops …

Two Phase Separator Settling Time

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 determined from the equation: where FD = drag force, Ib CD = drag coefficient A …

Two Phase Oil and Gas Separation

{0 Comments}

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.
