In the gravity settling section the liquid drops will settle at a velocity determined by equating the gravity force on the drop with the drag…
This is the bottom product from the vacuum distillation unit. Just as in the case of the atmospheric residue it has several options for its…
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 design pressure for a vessel is called its “Maximum Allowable Working Pressure” (MAWP). In conversation this is sometimes referred to simply as the vessel’s…
Figure 5-3 shows an alternate configuration known as a “bucket and weir” design. This design eliminates the need for a liquid interface controller. Both the…
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…
A bed of random packing typically consists of a bed support (typically a gas injection support plate) upon which pieces of packing material are randomly…
The choice of separator operating pressures in a multistage system is large. For large facilities many options should be investigated before a final choice is…
Three phase separator are designed as either horizontal or vertical pressure vessel. Figure 5-2 is a schematic of a horizontal separator. The fluid enters the…
In condensate stabilizers, trays generally have 70% equilibrium stage efficiency. That is, 1.4 actual trays are required to provide one theoretical stage. The spacing between…
