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…
This property of a fluid indicates its resistance to flow. It is a dynamic property, in that it can be measured only when the fluid…
The process of flotation improves the separation of the oil droplets from the water continuous phase. This goal is accomplished by increasing the difference in…
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…
A bed of random packing typically consists of a bed support (typically a gas injection support plate) upon which pieces of packing material are randomly…
Specific gravity of a liquid is the ratio of the density of the liquid at 60°F to the density of pure water. API gravity is…
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…
The way in which the process temperature is controlled varies. In a heater, a temperature controller measures the process temperature and signals a fuel valve…
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.
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…
