To perform a good troubleshoot on glycol dehydration equipment, you must know what the system is designed for and how the current conditions compare to that design. Sizing of a glycol unit is based on determining the correct contact tower to pair with a regeneration skid. Regeneration systems are sized for the circulation rate required to remove the water vapor from the natural gas stream. Random packing is used for smaller diameter towers typically under 20” Diameter.

A common way to dehydrate gases is the use of a glycol. The glycol absorbs the water from the wet gas stream, becomes heavier and sinks to the bottom of the contactor where it is expelled. Glycol dehydration involves putting glycol in contact with a stream of natural gas that contains water. A glycol unit is comprised of two major components, the contact tower, and the regeneration skid. Recent News.
