1. n. [Production Facilities]

A unit used to remove minute water particles from natural gas if dehydration was not attained using separators. A glycol dehydrator unit is usually composed of an absorber and a reboiler. The wet gas enters at the bottom of the absorber. As the wet gas percolates upward, it releases its water into the glycol solution and dry gas is obtained at the top of the absorber. When the glycol solution becomes saturated with water, the glycol solution is pumped through a reboiler, also called a reconcentrator, which boils the glycol-water mixture and separates the glycol from the water. After separation, the glycol can return to the absorber to contact additional wet gas.
