The major cause of foam in crude oil is the appearance of impurities, other than water, which are impractical to remove before the stream reaches…
As with vertical two-phase separators, a minimum diameter must be maintained to assure adequate gas capacity. In addition, vertical threephase separators must maintain a minimum…
Knowledge of the temperature and pressure of a gas stream at the wellhead is important for determining whether hydrate formation can be expected when the…
It is very rare that flow must be controlled in an oil field process. Normally, the control of pressure, level, and temperature is sufficient. Occasionally,…
Most commonly used water treating equipment items rely on the forces of gravity to separate the oil droplets from the water continuous phase. The oil…
The choice of separator operating pressures in a multistage system is large. For large facilities many options should be investigated before a final choice is…
For sizing a horizontal separator it is necessary to choose a seam-toseam vessel length and a diameter. This choice must satisfy the conditions for gas…
An oscillating droplet of oil becomes unstable when the kinetic energy is sufficient to make up for the difference in the surface energy between the…
In producing operations it is often necessary to handle waste water that may include water produced with crude oil, rain water, and washdown water. The…
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…
