Flash-Point Prediction for Partially Miscible Mixture of Methanol + Toluene + 2,2,4-trimethylpentane
Flash point is the most important variable used to characterize fire and explosion hazard of liquids. Herein, partially miscible mixtures are presented within the context of liquid-fiquid extraction processes and heterogeneous distillation processes. This paper describes development of a model for predicting the flash point of multiple partially miscible mixtures of flammable solvents. To co nfmn the predictive efficiency of the derived flash points, the model was verified by comparing the predicted values with the experimental data for the studied mixture: methanol + toluene + 2,2,4-trimethylpentane. Results reveal that immiscibility in the two liquid phases should not be ignored in the prediction of flash point. Overall, the predictive results of this proposed model describe the experimental data well when using the LLE and VLE parameters to estimate the tie lines and the flash point, respectively. Potential application for the model concerns the assessment of fire and explosion hazards, and the development of inherently safer designs for chemical processes containing partially miscible mixtures of flammable solvents.
