While this study addresses the uncertainties in D i,air (T, P ), P Sat (T ), and T hr i , it should be noted that temperature and pressure (T, P ) can also fluctuate during experimentation, affecting the results. However, these factors are not considered the most critical variables for the scope of this work. Another important parameter is the area at the gas-liquid interface A l,g , commonly set at 0.071 m 2 . However, no rational basis exists for this specific value in the literature. Consequently, this study does not account for the uncertainty associated with this particular parameter. Finally, the uncertainty in the activity coefficient γ(x, T ) significantly influences predictions, as quantified in distillation processes in . Unfortunately, an accurate assessment of the uncertainty of this variable requires multiple measurements of liquid-vapor equilibrium, which are unavailable for the case study mixture explored here, consisting of limonene, geraniol, vanillin, and ethanol.
