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…

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…
Before choosing a wall thickness it is necessary to choose a pressure rating for the coil. Typically, the high-pressure coil (L1) is rated for the…
Erosional flow criteria will almost always govern in choosing the diameter. Sometimes it is necessary to check for pressure drop in the coil. Typically, pressure…
In order to choose the coil length and diameter, a temperature must first be chosen upstream of the choke; the higher Th the longer the…
The area of the fire tube is normally calculated based on a heat flux rate of 10,000 Btu/hr-ft2. The fire-tube length can be determined from:…
To calculate the heat duty it must be remembered that the pressure drop through the choke is instantaneous. That is, no heat is absorbed or…
As shown in Figure 5-2, the well stream enters the first coil at its flowing tubing temperature and pressure. Alternatively, it could be choked at…
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…
