A central composite design and response surface methodology was used to study the influence of the process variables temperature (T), presscake moisture content (MC) and leaching time (LT) on the decontamination process. A significant squared MC effect was observed, resulting in an optimum leaching rate at 27% MC.

Chemical process industries deal with production which further utilizes reaction followed by separation of the reaction mixtures. Reactive distillation is a new technique of combination of both reaction and separation in a single unit beneficial for equilibrium-limited reactions and also cost-effective. This makes it a highly complex process because many parameters involved in …

distillation columns are complex, making them difficult to predict and control. Lack of understanding of the mass transfer and flow dynamics occurring between phases inside these devices is the primary barrier to improving their energy and process efficiencies. New, advanced computational techniques to model distillation column operation

THE DISTILLATION OF ALCOHOL - Distillers Wiki

Distillation is simply a purification process which not only doesn’t make alcohol but is incapable of making it. Alcohol is made by fermentation, not by distillation, so it might be expected that fermentation would be the process subject to control. This is not so however ---- amateur beer- and wine-makers are free

Figure 4 depicts the structure of the distillation process by dividing the vapor/liquid equilibrium information into three distinct zones of process and equipment requirements: stripping, rectifying and dehydration. This division is the basis for the design of equipment and systems to perform the distillation tasks. Considerations in ...
