With the known temperatures on each end of the coil, the heat duty for each coil can be calculated from the heat transfer theory. Since…
The first form of a plate coalescer was the parallel plate interceptor (PPI). This involved installing a series of plates parallel to the longitudinal axis…
To assure that the liquid and gas reach equilibrium at separator pressure a certain liquid storage is required. This is defined as “retention time” or…
Shell-and-tube heat exchangers are cylindrical in shape, consisting of a bundle of parallel tubes surrounded by an outer casing (shell). Both the tube bundle and…
A vent scrubber is a two-phase separator designed to remove the liquid from the relieving fluids before the gas is flared or vented. The liquid…
This equation, which is also sometimes called the Weisbach equation or the Darcy-Weisbach equation, states that the friction head loss between two points in a…
The oil must be held at temperature for a specific period of time to enable de-emulsifying the water-in-oil emulsion. This information is best determined in…
In specifying the size of a treater, it is necessary to determine the diameter (d), length or height of the coalescing section (Leff or h),…
In long horizontal vessels it is necessary to install wave breakers, which are nothing more than vertical baffles spanning the gas-liquid interface and perpendicular to…
A typical spherical separator is shown in Figure 4-3. The same four sections can be found in this vessel. Spherical separators are a special case…
