Foam at the interface may occur when gas bubbles are liberated from the liquid. This foam can be stabilized with the addition of chemicals at…

In long horizontal vessels it is necessary to install wave breakers, which are nothing more than vertical baffles spanning the gas-liquid interface and perpendicular to…
There are many types of inlet diverters. Two main types are baffle plates (shown in Figure 4-6) and centrifugal diverters (shown in Figure 4-7). A…
A scrubber is a two-phase separator that is designed to recover liquids carried over from the gas outlets of production separators or to catch liquids…
Cyclone separators are designed to operate by centrifugal force. These designs are best suited for fairly clean gas streams. The swirling action of the gas…
A typical spherical separator is shown in Figure 4-3. The same four sections can be found in this vessel. Spherical separators are a special case…
Figure 4-2 is a schematic of a vertical separator. In this configuration the inlet flow enters the vessel through the side. As in the horizontal…
Separators are designed in either horizontal, vertical, or spherical configurations. Figure 4-1 is a schematic of a horizontal separator. The initial gross separation of liquid…
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.
