Adding heat to the incoming oil/water stream is the traditional method of separating the phases. The addition of heat reduces the viscosity of the oil…
The ASME code requires every pressure vessel that can be blocked In to have a relief valve to alleviate pressure build up due to thermal…
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…
Most oil treating on offshore facilities is done in vertical or horizontal treaters, such as those described in “Crude Oil Treating System“. Figure 2-8 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…
Liquid carryover and gas blowby are two common operating problems. Liquid carryover occurs when free liquid escapes with the gas phase and can indicate high…
The maximum and minimum design temperatures for a vessel will determine the maximum allowable stress value permitted for the material to be used in the…
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,…
Before the vessel fabrication can proceed, the fabricator will develop complete drawings and have these drawings approved by the representative of the engineering firm and/or…
This is the bottom product from the atmospheric distillation of the crude oil. Most crude oils are distilled in the atmospheric crude oil tower to…
