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…
Coalescing of the small water drops dispersed in the crude can be accomplished by subjecting the water-in-oil emulsion to a high-voltage electrical field. When a…
The required heat duty, film coefficients, conductivity, etc. for a shell and tube heat exchanger can be calculated using the procedures in Heat Transfer Theory,…
It is also necessary to control the gas/liquid interface or the oil/water interface in process equipment. This is done with a level controller and liquid…
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…
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…
It is normally a good idea to include a simple vortex breaker as shown in Figure 4-9 to keep a vortex from developing when the…
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 the interest of energy conversion, process heat can be obtained from a heat recovery unit in which heat is recovered from turbine or reciprocating…
In order to choose the coil length and diameter, a temperature must first be chosen upstream of the choke; the higher Th the longer the…
