Abstract Plasmas in contact with liquids can degrade organic molecules a solution, as reactive oxygen and nitrogen species produced the plasma solvate into liquid. Immersing small droplets (tens of microns diameter) more rapidly activate liquid compared to treating large volume smaller surface-to-volume ratio. The interactions between radio frequency glow discharge sustained He/H 2 O water drop...

Existing refinery distillation systems are highly energy-intensive, and have complex column configurations that interact strongly with the associated heat exchanger network. An optimisation approach is developed for existing refinery distillation processes. The optimisation framework includes shortcut models developed for the simulation of the existing distillation column, and a retrofit shortc...

In industry, many separation processes involve the separation of multicomponent mixtures using distillation. There are many distillation configurations that can carry out the same overall separation process. These configurations use an equal number of distillation columns, but they differ significantly in energy consumption. Therefore a major challenge for a practitioner is the identification o...

This work presents a reactive distillation column for the catalytic disproportionation of trichlorosilane to silane which includes three consecutive reversible reactions. This reaction system is however characterized by a large distinction in the boiling points of the components, which make the reactive distillation extremely favored. Nevertheless, the normal reactive distillation column posses...

The structure of thermally coupled distillation systems offers several control challenges arising from the transfer of vapor (or liquid) streams between columns. In particular, the presence of recycle streams for coupled schemes has led to the notion that control problems might be expected during the operation of these systems, in contrast to the rather well-known behavior of conventional disti...

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...
