The 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 henry’s law information for the natural gas out of TEG/H2O solutions.
