In two field natural gas dehydration units, TEG (Tri Ethylene Glycol) losses are almost 10X those accepted by the industry (0.93 gals per mmscfd VS ~0.1 gal per mmscfd of gas treated). The fabricator has come back to us and said that his design results in high glycol losses very close to these numbers from the reboiler (still column). These losses are outrageous causing us very high opex. Has anyone seen these high glycol losses from a system that is free of foaming issues and is dehydrating a very lean gas at 300 psig??
Appreciate your feedback.
