Thermogravimetric measurement of the equilibrium vapour pressure: Application to water and triethanolamine

A model that describes the pure evaporation kinetics is introduced. This model takes into account gas diffusion and convective gas transport; it describes the evaporation kinetics under the general conditions of thermogravimetric measurements. The model is used to determine the equilibrium vapour pr...
