Abstract
In this study, enrichment in major component of spearmint oil has been
studied by continuous multicomponent distillation. A mathematical model was
evaluated to predict the enrichment by multicomponent distillation of
spearmint oil. The aim of the work was to obtain simulation data to compare
with experimental data of spearmint oil enriching. The simulation model is
based on bubble point method ,the Wang-Henke algorithm and predictive
Soave-Redlich-Kwong (PSRK) equation. In this method, MESH equations are
solved and a diagonal matrix method for solving equations is used. The model
was validated by experimental data obtained from a pilot-plant system, where
a continuous distillation column with trays of one to five numbers has been
used. The simulation was able to predict satisfactory the experimental data.
The results of simulation and experiments show that the major component of
spearmint essential oil is enriched from 31% to 62.04% by the distillation
column with five trays. The results show that the addition of a tray to the
distillation column with a low number of trays, have more effective relative
to add a tray to the distillation column with higher trays. The results
indicate that increasing of reflux ratio from 2 to 3 increases separation of
the major component from 62.04% to 67.04%.
