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 fraction of any one component that flashes to gas at any stage in a process is a function of the temperature, pressure, and composition…
The maximum allowable stress values to be used in the calculation of the vessel’s wall thickness are given in the ASME Code for many different…
It is normally a good idea to include a simple vortex breaker as shown in Figure 4-9 to keep a vortex from developing when the…
Laboratory testing of a particular oil at various temperatures is the most reliable method of determining how an oil behaves. ASTM D 341 outlines a…
These units are designed to allow hydrates to form and to melt them with the heat of the incoming gas stream before they can plug…
Hydrocyclone separators, sometimes called enhanced gravity separators, use centrifugal force to remove oil droplets from oily water. As shown in Figure 7-16, static hydrocyclone separator…
The gravity settling devices previously discussed make use of closely spaced internals to reduce the distance an oil droplet must rise to meet a coalescing…
The maximum and minimum design temperatures for a vessel will determine the maximum allowable stress value permitted for the material to be used in the…
A gas-processing plant, is designed to recover ethane, propane, butane, and other natural gas liquids from the gas stream. A condensate stabilizer also recovers some…
