All ASME Code vessels are inspected by an approved Code inspector. The manufacturer will supply Code papers signed by the inspector. The nameplate on the…
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…
The simplest form of primary treating equipment is a settling (skim) tank or vessel. These items are normally designed to provide long residence times during…
Water Treatment describes choosing a process for this subsystem, including vessel and open drains. Figure 2-13 shows an enlargement of the watertreating system for the…
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…
There are usually two naphtha cuts produced from most crude. These are: Light naphtha (sometimes called light gasoline) Heavy naphtha. Both these streams are the…
There are many types of inlet diverters. Two main types are baffle plates (shown in Figure 4-6) and centrifugal diverters (shown in Figure 4-7). A…
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…
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,…
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…
