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…
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…
In the absence of any laboratory data, correlations exist that relate viscosity and temperature, given the oil gravity. The following equation relating viscosity, gravity, and…
In dispersed gas units gas bubbles are dispersed in the total stream either by the use of an inductor device or by a vortex set…
Separator operation can be adversely affected by an accumulation of paraffin. Coalescing plates in the liquid section and mesh pad mist extractors in the gas…
The specific gravity difference between the dispersed water droplets and the oil should result in the water “sinking” to the bottom of the treatment vessel.…
The design pressure for a vessel is called its “Maximum Allowable Working Pressure” (MAWP). In conversation this is sometimes referred to simply as the vessel’s…
For distillation services, as in condensate stabilization, tray design is well understood, and many engineers are more comfortable with trays than with packing. In the…
Mist extractors can be made of wire mesh, vanes, centrifugal force devices, or packing. Wire mesh pads (Figure 4-10) are made of finely woven mats…
Nozzles should be sized according to pipe sizing criteria, such as those provided in API RP 14E. The outlet nozzle is generally the same size…
