A scrubber is a two-phase separator that is designed to recover liquids carried over from the gas outlets of production separators or to catch liquids…
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…
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.…
The Reynolds number is a dimensionless parameter that relates the ratio of inertial forces to viscous forces. It can be expressed by the following general…
As more stages are added to the process there is less and less incremental liquid recovery. The diminishing income for adding a stage must more…
The sensible heat duty for the oil phase is: where Q0 = oil flow rate, bpd SG = oil specific gravity C0 = oil specific…
Tube holes cannot be drilled very close together, since this may structually weaken the tube sheet. The shortest distance between two adjacent tube holes is…
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…
Separators are designed in either horizontal, vertical, or spherical configurations. Figure 4-1 is a schematic of a horizontal separator. The initial gross separation of liquid…
A double-pipe exchanger is made up of one pipe containing the tube fluid concentric with another pipe, which serves as the shell. The tube is…
