Background Hydro-distillation (HD) method is a traditional technique which is used in most industrial companies. Microwave-assisted Hydro-distillation (MAHD) is an advanced HD technique utilizing a microwave oven in the extraction process. Methods In this research, MAHD of essential oils from the aerial parts (leaves) of rosemary (Rosmarinus officinalis L.) was studied and the results were co...

The present work elaborates the process design methodology for the evaluation of the distillation systems based on the economic, exergetic and environmental point of view, the greenhouse gas (GHG) emissions. The methodology proposes the Heat Integrated Pressure Swing Distillation Sequence (HiPSDS) is economic and reduces the GHG emissions than the conventional Extractive Distillation Sequence (...

The compostion of the oils from flower and leaf of Achillea mellifolium L. subsp. mellifolium were collected during the flowering priod from Lar area to Damavand montain, altitude 3400 m in July 2003. The essential oils obtained by different methods of distillation (steam distillation and hydro-distillation), the percentage of oils for flower and leaf by steam distillation were 0.2 and 0.05% an...

the genus boswellia is one of the 17 genera belonging to burseraceae family. in this study resin of boswellia carteri birdwoodcollected or purchased from tehram herbal market as a food and non-food for chemical analysis. the essential oils of the resins of boswellia carteri birdwoodobtained by different methods of distillation (water distillation, steam distillation and hydro-steam distillation...

Control properties of thermally coupled distillation arrangements for the separation of multicomponent mixtures were compared to those of conventional distillation sequences. Seven thermally coupled schemes were investigated. The preliminary steady – state design of complex schemes was obtained by starting from a conventional distillation sequences and then optimizing for minimum energy consump...

Ethanol production from agro-based raw materials normally involves two major steps, fermentation and distillation. These steps are reviewed, mainly in relation to molasses, which is the most common raw material in tropical countries. The specific effect on fermentation efficiency of molasses quality in terms Fermentable Sugars, the ratio of fermentable to non-fermentable solids, Volatile Acids,...

The control properties of thermally coupled distillation sequences for the separation of five – component mixtures of hydrocarbons were compared to those of conventional distillation sequences. Seven thermally coupled arrangements were investigated. The preliminary steady – state designs of complex schemes were obtained by starting from conventional distillation sequences and then optimizing fo...

In this contribution, a different pressure thermally coupled extractive distillation process has been applied on the separation of propylene and propane with aqueous acetonitrile (ACN) solution as entrainer. The novel distillation process integration is the combination of different pressure thermally coupled distillation (DPTCD) and extractive distillation (ED). Both the new process and the con...
