We are using TEG for dehydrating natural gas and one regeneration system for TEG. We are facing problem of glycol loss. How can we reduce that? Reducing flow of stripping gas can help, I think.
Have an insight or suggestion?

Re: Reducing glycol loss when using TEG19 September 2006 at 1:29pmThe glycol loss can be calculated by knowing the partial pressure of the glycol at the operating temperature and the molar flow of discharge gas. Several things can be done to minimize glycol loss, including reducing the operating temperature (strong function due to vapor pressure curve) or utilizing a vent condenser on the discharge gas. You must know the vapor/liquid equilibrium data for TEG/H2O, as well as the henrys law information for the natural gas out of TEG/H2O solutions.
