Three process requirements must be met for gas to be dried in a standard glycol dehydration unit: 1. The gas velocity through the contactor tower…

The field supervisor’s first indication of a flooded contactor tower is usually a report of excessive glycol loss. A check of a lowpoint bleeder on…
The hot glycol from the reboiler is cooled by heat exchange with the wet glycol from the contactor. This heat transfer typically takes place in…
The gas exiting the top of the contactor in Figure 6-1 can be assumed to be in equilibrium with the reboiled—i.e., dry—glycol. The higher the…
The first oddity I noticed was the noise from the vents associated with the individual reboilers. As Figure 6-1 shows, the expanding gas, used to…
Removing most of the water vapor from the gas is required by most gas sales contracts, because it prevents hydrates from forming when the gas…
