COMPARISON BETWEEN EXTRACTION ESSENTIAL OIL BY STEAM DISTILLATION AND MICROWAVE ASSISTED EXTRACTION PROCESSES
Keywords:
Extraction processes, Microwave Assisted Extraction, Steam Distillation (SD), Essential OilAbstract
Extraction processes have been developed to be more eco-friendly applied processes, the most popular conventional method to extract essential oils is a steam distillation (SD), whereas a new technic to heat the plants faster is to use microwave cavity. This work is aimed to compare two extraction methods scaled up based on the experimental results obtained using microwave assisted extraction (MAE) for essential oil extraction from lavender flowers. The results proved that the capital cost for MAE mainly increased by microwave cavity and microwave generator, their cost were 8 times higher than that of conventional method steam distillation, while the operating cost for both of them are almost the same. However, MAE over short time and small area to be applied, to extract an essential oil from Lavender flowers. Whereas the SD has an important advantage over the microwave assisted extraction in terms of safety and cost
