Effect of Number of Fractionating Trays on Reactive Distillation Performance

Sneesby et al. recently suggested that adding trays in the stripping and rectifying sections of a reacti®e distillation column can degrade performance. This effect, if true, is not only counterintuiti®e, but ®ery disturbing because it suggests that the design of reacti®e distillation columns cannot use conser®ati®e estimates of tray numbers, that is, we cannot simply add excess trays, as in con...

Vacuum Booster for Distillation Process

Vacuum membrane distillation on a microfluidic chip.

A multilayered microfluidic chip used for vacuum membrane distillation is designed, fabricated and tested by rectification of a water-methanol mixture.

Preliminary Evaluation for Vacuum Membrane Distillation (VMD) Energy Requirement

The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...
