Control valves are used throughout the process to control pressure, level, temperature, or flow. It is beyond the scope of this text to discussthe differences…
In the past, it was common to direct the water to be treated through a bed of excelsior or another similar medium, as shown in…
It is possible to use a coalescing media to promote coalescence of the water droplets. These media provide large surface area upon which water droplets…
To maintain pressure on a separator, a liquid seal must be effected in the lower portion of the vessel. This liquid seal prevents loss of…
It should be clear from the description of LTX units that the lower pressure separator in an LTX unit is a simple form of cold-feed…
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…
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…
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…
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),…
