Abstract

This study proposes a scheme for optimizing the extraction of Damask rose essential oil under supercritical conditions. The

eff ects of temperature, pressure, and static time on the extraction process were investigated using response surface methodology

(RSM). The results showed that increasing pressure and static time had a positive eff ect on extraction, while increasing

temperature had a negative eff ect. The optimal conditions for extraction were found to be 45 °C, 180 bar, and 180 min, with

an effi ciency of approximately 92% and a content of 54.2% for 2-phenylethanol. The extraction process was modeled using

Peng–Robinson equations based on equilibrium data, with values of k ij and l ij determined as 0.311 and 0.037, respectively.

The separation unit was simulated using Aspen Hysys, with operating conditions set at 20 °C and 55 bar. An economic evaluation

of the industrial plan was conducted using Aspen Plus. The fi xed investment cost (FIC) for the project was calculated

as $412,000, and the manufacturing cost was estimated at $220,000. The capital return period for the project was determined

to be 8 months, indicating that the initial investment would be recovered within this timeframe.
