In designing dehydration units for natural gas, several critical parameters exist which can be varied to achieve a specified dew point depression. This paper studies the effects of varying the glycol flow rate, number of stages in the contactor, reboiler temperature, and stripping gas rate on water content in glycol dehydration units. The effect of high carbon dioxide composition in the feed is also presented. Finally, the emissions of aromatic (BTEX) and other VOC's from the regenerator and flash will be considered.
