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…
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…
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…
Balanced relief valves are spring-loaded valves that contain a bellows arrangement to keep back-pressure from affecting the set point. Figure 13-4 shows a cross section…
Vessel Supports Small vertical vessels may be supported by angle support legs, as shown in Figure 12-11. Larger vertical vessels are generally supported by a…
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…
Some treaters use an electrode section. Figure 6-11 illustrates a typical design of a horizontal electrostatic treater. The flow path in an electrostatic treater is…
Removing water from crude oil often requires additional processing beyond gravitational separation. In selecting a treating system, several factors should be considered to determine the…
In specifying the size of a treater, it is necessary to determine the diameter (d), length or height of the coalescing section (Leff or h),…
The droplet diameter is the most important single parameter to control to aid in water settling since this term is squared in the settling equation.…
