System for the dehydration of glycolAuthor(s): Tina Parks
A system that provides absorption dehydration is the glycol dehydration system, and a liquid desiccant inside the system provides a way to remove water from the system the circulation of fuel. The initial primary chemical in this system, ethylene glycol (HOCH CH OH) 2 2, has a very strong affinity for water. When in contact with a flow of water-moist herbal fueling, the ethylene glycol absorbs the water from the fueling circulation. Since technology has advanced, glycol dehydration now involves using an aqueous solution of a glycol by-product, where the glycol can be either Diethylene Glycol (DEG) or Triethylene Glycol. Initially, the system used ethylene glycol as the absorbent.
