Glycol Contact Towers

The glycol contact tower is the key component to a dehy system as it is the vehicle used to remove the water from the gas by means of circulating glycol. The tower is a pressure vessel with an integral scrubber and absorber section, each having specific requirements for the tower to function. Contact towers functions to contact lean glycol solution with the wet inlet gas. Various contact mechanisms can be employed with the most commonly used are bubble cap trays.

The scrubber section of the tower removes free liquids from the gas while the absorber section is used to make the contact between the gas and the glycol. The removing of the water vapor from the gas happens in the absorber section of the tower using either bubble cap trays, random packing, or structured packing.
