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…
Figure 2-7 is an enlargement of the FWKO of Figure 2-1 to show the amount of detail that would be expected on a process flowsheet.…
In our example process the high- and intermediate-stage separators are two-phase, while the low-pressure separator is three-phase. This is calleda “free water knockout” (FWKO) because…
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…
The discussion to this point has focused on a situation where all the wells in a field produce at roughly the same flowing tubing pressure,…
As more stages are added to the process there is less and less incremental liquid recovery. The diminishing income for adding a stage must more…
Figure 2-5 deals with a simple single-stage process. That is, the fluids are flashed in an initial separator and then the liquids from that separator…
Because of the multicomponent nature of the produced fluid, the higher the pressure at which the initial separation occurs, the more liquid will be obtained…
The production system begins at the wellhead, which should include at least one choke, unless the well is on artificial lift. Most of the pressure…
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,…
