At constant pressure, the water content of the inlet gas increases as the inlet gas temperature increases. For example, at 1,000 psia and 80°F gas…

The commonly available glycols and their uses are: 1. Ethylene glycol—High vapor equilibrium with gas so tend to lose to gas phase in contactor. Use…
Since there is a large difference between the boiling point of triethylene glycol (546°F) and water (212°F), the still column can be relatively short (10…
On larger streams filter separators are used as inlet scrubbers to further reduce glycol contamination and thus increase the life of the glycol charge. Due…
Most glycol dehydration processes are continuous. That is, gas and glycol flow continuously through a vessel (the “contactor” or “absorber”) where they come in contact…
By far the most common process for dehydrating natural gas is to contact the gas with a hygroscopic liquid such as one of the glycois.…
The first step in evaluating and/or designing a gas dehydration system is to determine the water content of the gas. The water content of a…
Gas dehydration is the process of removing water vapor from a gas stream to lower the temperature at which water will condense from the stream.…
