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…
Each relief valve should be equipped with inlet piping no smaller than the valve inlet flange size, and inlet piping should be as short as…
The design pressure for a vessel is called its “Maximum Allowable Working Pressure” (MAWP). In conversation this is sometimes referred to simply as the vessel’s…
Two-Phase Flow There are no precise formulas for calculating orifice area for twophase flow. The common convention is to calculate the area required for 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),…
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…
The specific gravity difference between the dispersed water droplets and the oil should result in the water “sinking” to the bottom of the treatment vessel.…
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…
Conventional Valve, Balanced-Bellows Valve, or Pilot-Operated Valve The corresponding equations for liquid flow are the following: Note that a preliminary orifice size must be determined…
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…
