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…
Control valves are used throughout the process to control pressure, level, temperature, or flow. It is beyond the scope of this text to discussthe differences…
Most oil treating on offshore facilities is done in vertical or horizontal treaters, such as those described in “Crude Oil Treating System“. Figure 2-8 is…
There are four major types or basic configurations of separators, generally available from manufacturers which are as follows: 1. Vertical 2. Horizontal Single Tube 3.…
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…
It is customary to express the energy contained in a fluid in terms of the potential energy contained in an equivalent height or “head” of…
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.
To maintain pressure on a separator, a liquid seal must be effected in the lower portion of the vessel. This liquid seal prevents loss of…
This process uses propylene carbonate as a physical solvent to remove CO2 and H2S. Propylene carbonate also removes C2+ hydrocarbons, COS, SO2, CS2, and H2O…
This is not strictly a cut but consists of all the light material in the crude absorbed into the total overhead distillate from the crude…
