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…
There are usually two naphtha cuts produced from most crude. These are: Light naphtha (sometimes called light gasoline) Heavy naphtha. Both these streams are the…
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 way in which the process temperature is controlled varies. In a heater, a temperature controller measures the process temperature and signals a fuel valve…
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…
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…
This fraction is usually the first side stream of a conventional atmospheric distillation unit. It may be cut to meet a burning oil specification or…
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…
A bed of structured packing consists of a bed support upon which elements of structured packing are placed. Beds of structured packing typically have lower…
These are thin diaphragms held between flanges and calibrated to burst at a specified static inlet pressure. Unlike relief valves, rapture discs cannot reseal when…
