Water Treatment describes choosing a process for this subsystem, including vessel and open drains. Figure 2-13 shows an enlargement of the watertreating system for the…
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…
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…
Remembering that the weight of each component is the number of moles of that component times its molecular weight (pounds = MW X moles), the…
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),…
One method of assuring that hydrates do not form is to assure that the amount of water vapor in the gas is always less than…
In modern refinery practice the distillation of atmospheric residue is accomplished under high vacuum conditions in a specially designed tower whose internal equipment ensures a…
The first step in choosing a water treating system is to characterize the influent water streams. It is necessary to know both the oil concentration…
The relief header is a system of piping connecting the outlets of all the relief valves into a common pipe or header that goes to…
The flow rate for gas through a given orifice area or the area required for a given flow rate is obtained by:
