Water distillation is mainly concerned with evaporation and then condensation water vapor evaporated, where as alcohol still need to selectively seperate low volatile etanol using heat ,as well as can condense selectively the ethanol and hence need
column.Thus water distiller can be mainly smalltank type ,less condensation problem ,where as ethanol still is column.Hence tey need to be diffrent in design , eventhouh they all envolve similar process as you outlined. We here do like the design for small scale equipment for sustainable biofuel process
developments.using air as coolant and then recover the energy for drying can be possible ,but yet taht type of noval distillation units need to evolved .You can try one taht can save the huge energy cost of ethanol as one need 5 Kg of steam for every 1 l of ethanol.

I have a question for the group. Would a water distiller like the kind found at www.waterdistiller.com be similar to an alcohol still? Usually an alcohol still has a column and uses water as the coolant for the condenser. These water distillers use a coil that is air cooled.
