Abstract

The equation of state Soave-Redlich-Kwong (SRK) and its modification (predictive SRK or PSRK) are applied to simulate multicomponet distillation, which separate main component of spearmint essential oil. The simulation model is based on bubble point method, and the Wang-Henke algorithm. Spearmint essential oil is considered in the study and the original experimental data were obtained from pilot plant. The models were validated by continuous distillation column with trays of one to five numbers. The work allows concluding on the advantages, disadvantages and expected accuracy of SRK and PSRK equations of state for multicomponent distillation data in the system as those studied..
