The oil must be held at temperature for a specific period of time to enable de-emulsifying the water-in-oil emulsion. This information is best determined in…
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.…
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 wellstream enters the first coil at its flowing tubing temperature and pressure. Alternatively, it could be choked at the…
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…
A kinetic inhibitor is a polymeric chemical that, when added to a production stream, will not change the hydrate formation temperature but will delay the…
First the amount of water that will be condensed will be determined from Figure 4-6, assuming the gas is saturated at reservoir conditions. Water content…
1. Chemicals can be injected into the production stream to depress the likelihood of significant hydrate formation. 2. A therrnodynamic inhibitor alters the chemical potential…
Choking, or expansion of gas from a high pressure to a lower pressure, is generally required for control of gas flow rates. Choking is achieved…
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…
