The Simulation of the TBP Curve of Thymol Essence and the Separation of Natural Components with ASPEN plus Software

Abstract

Based on the analysis of GCMASS device, the components of the type of Thymol essence prepared from Nishabour maintains, consist of five main components namely, ?-Pinene, ?-Terpinene, P-Cymene, ?-Terpinene, and Thymol, each of which has the percentage of 1.118, 3.831, 25.815, 14.771, and 54.465 respectively in the essence. Moreover, based on the experiment, the boiling point curve for this essence was achieved, and according to the results of the analysis of the boiling point curve, the simulation for this complex mixture for achieving the characteristics of the essence was done. The simulation of the separation unit of the main components in the pressure range of 44KPa to 101.3KPa showed that with the increase of the pressure, Thymol mole fraction increases from 0.9399 to 0.9496 in the product of the bottom of the distillation column. With the increase of the total pressure of the distillation column from 44KPa to 101.3KPa, the minimum of the return reflux decreases from 17.7 to 13.93.
