Abstract

Essential oil is one of Indonesia's agro-industrial export commodities, one of which is essential oil from Moringa oleifera leaves. This study aims to study the results of the yield and analyze the essential oil content of Moringa oleifera leaves using the steam distillation method and Soxhlet extraction using ethanol and isopropyl alcohol as a solvent. The fresh feed was either directly extracted or pre-treated using an oven and then followed by several stages of extraction. The pre-treatment of fresh feed was carried out in the oven at 70°C for 1 hour. Atmospheric steam distillation was carried out at 100°C for 6 hours using 500 ml of distilled water. In the case of soxhlet extraction, the temperature was set at the boiling point of the solvent for 6 hours. Once soxhlet extraction was complete, the essential oil was separated from the solvent by distillation. After various extraction processes, the essential oils were analyzed for their compound content using GC-MS. Based on the results of the study, the highest yield of 29.04% was obtained from the treated feed using two stages of soxhlet extraction variable with ethanol as solvent.

Abstract

This study conducted a Computational Fluid Dynamics (CFD) simulation to analyze the hydrodynamics and mass transfer in a distillation column, focusing on the impact of adding steel wool packing on a sieve tray. Tray columns are commonly used in distillation processes but have drawbacks such as low separation efficiency and high pressure drop due to uneven flow distribution. As a solution, modifying the column by adding packing above the sieve tray has been proven to enhance mass transfer and tray efficiency. The study employed a multiphase Eulerian model, the k-epsilon turbulence model, and the species transport model to simulate a binary ethanol-water system. The simulation results show that the addition of steel wool packing produces smaller and more uniform bubbles, thereby increasing the interfacial area and the contact time between vapor and liquid. This leads to a more structured gas flow and a higher ethanol vapor concentration at the tray outlet, indicating improved separation efficiency compared to using sieve trays alone. This research provides an in-depth understanding of the internal physical phenomena that support the performance enhancement of distillation columns through the addition of packing.
