Glycol Dehydration

 

The Application

Glycol dehydration is an adsorption process in which glycol, a liquid solvent, is used to remove water vapor from natural gas. Glycol is brought into contact with the wet gas stream in a contactor tower, and then dry natural gas is transported out of the tower and into a carbon bed to remove hydrocarbons from the gas before further processing

 

The Problem

Solid and liquid contaminants in the wet natural gas cause or contribute to:
 

  • Glycol foaming in the contactor tower, resulting in less water vapor being adsorbed
  • Carbon bed fouling and downstream equipment failure
  • Product that does not meet specification
  • Increased maintenance costs and energy usage

 

The Solution

Two-stage coalescing for removal of liquids and particles prior to the wet natural gas entering the contactor tower will prevent foaming and downstream equipment failure. A coalescing filter upstream of the carbon bed will help to extend its life, and a particulate filter downstream of the unit will remove carbon fines and further protect downstream equipment.
