A pipe that releases gas to disperse into the atmosphere is called a vent. If the gas is burned at the tip, it is called…
In order to develop a treater design procedure, the water droplet size to be used in the settling equation to achieve a given outlet water…
Tube holes cannot be drilled very close together, since this may structually weaken the tube sheet. The shortest distance between two adjacent tube holes is…
The gravity settling devices previously discussed make use of closely spaced internals to reduce the distance an oil droplet must rise to meet a coalescing…
In the gravity settling section the liquid drops will settle at a velocity determined by equating the gravity force on the drop with the drag…
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…
In condensate stabilizers, trays generally have 70% equilibrium stage efficiency. That is, 1.4 actual trays are required to provide one theoretical stage. The spacing between…
A bed of structured packing consists of a bed support upon which elements of structured packing are placed. Beds of structured packing typically have lower…
The most common form of parallel plate interceptor used in oil facilities is the corrugated plate interceptor (CPI). This is a refinement of the PPI…
Pressure Relief Devices All pressure vessels should be equipped with one or more pressure safety valves (PSVs) to prevent overpressure. This is a requirement of…
