Pilot-operated relief valves use the pressure in the vessel rather than a spring to seal the valve and a pilot to activate the mechanism. Figure…
Plate coalescers are skim tanks or vessels that use internal plates to improve the gravity separation process. Various configurations of plate coalescers have been devised.…
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,…
Two-Phase Flow There are no precise formulas for calculating orifice area for twophase flow. The common convention is to calculate the area required for the…
If the flow rate of the inlet stream is known in moles per day then the number of moles per day of gas flow can…
For sizing a horizontal three-phase separator it is necessary to specify a vessel diameter and a seam-to-seam vessel length. The gas capacity and retention time…
The oil must be held at temperature for a specific period of time to enable de-emulsifying the water-in-oil emulsion. This information is best determined in…
This property of a fluid indicates its resistance to flow. It is a dynamic property, in that it can be measured only when the fluid…
The major cause of foam in crude oil is the appearance of impurities, other than water, which are impractical to remove before the stream reaches…
Head Bernoulli is a term that refers to the total energy of a fluid at a given point in a steady flow system. It consists…
