Gas Dehydration Units
(Glycol Dehydrator, Dehy, Dehydrator, Gas dehydrator, Gas dryer, TEG unit)
Gas Dehydration Units or “Dehy’s” are equipment that dehydrate the gas from a process stream down to a specific water content acceptable for sale to the pipeline (most commonly spec if <7lbs).
Dehy’s are placed after separation and compression with a Coalescer immediately upstream of the Dehy tower, sales line, Joule-Tomson unit and Cryogenic turbo expanders. Dehy’s are a low-cost way to dehydrate large and small volumes of gas at higher pressures above 700 psig.
