A vent scrubber is a two-phase separator designed to remove the liquid from the relieving fluids before the gas is flared or vented. The liquid…
In the past, it was common to direct the water to be treated through a bed of excelsior or another similar medium, as shown in…
Next to sales contract specifications, corrosion protection ranks highest among the reasons for the removal of acid gases. The partial pressure of the acid gases…
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…
For an oil and gas separator to accomplish its primary functions, pressure must be maintained in the separator so that the liquid and gas can…
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…
A typical spherical separator is shown in Figure 4-3. The same four sections can be found in this vessel. Spherical separators are a special case…
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…
The flow of a compressible fluid through an orifice is limited by critical flow. Critical flow is also referred to as choked flow, sonic flow,…
