C5PG Glycol Dehydration

Triethylene glycol (TEG) is a common liquid desiccant employed to remove water vapor from natural gas streams. C5 Process Group, Inc. (C5PG) is an industry leader in providing glycol dehydration equipment for natural gas storage, gas transmission and gas gathering applications.

Wet gas enters the absorber contacting the lean, dry glycol in a structured packed or trayed section where water vapor is absorbed into the glycol. Rich, water laden glycol exits from the lower section of the absorber and is piped to a regeneration system while dry gas exits the top of the absorber tower.

Rich glycol is heated to approximately 400°F as water is boiled off (regeneration) and exits through the vent atop the reboiler still column.

Efficient water removal depends on the following: gas pressure and temperature, gas composition, glycol circulation rate, glycol purity, and efficiency of glycol to gas contact.
