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…
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…
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…
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…
It is important to be able to estimate vessel weights, since most cost estimating procedures start with the weight of the vessel. The vessel weight,…
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.…
In the interest of energy conversion, process heat can be obtained from a heat recovery unit in which heat is recovered from turbine or reciprocating…
Figure 13-2 shows a cross section of a conventional relief valve and Figure 13-3 is a schematic that shows the valve’s operation. Convention al relief…
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…
Foam at the interface may occur when gas bubbles are liberated from the liquid. This foam can be stabilized with the addition of chemicals at…
