Abstract:
A system and method for producing substantially anhydrous ethanol, methanol or other volatile chemicals includes: (a) a first distillation stripping column or column set with overhead vapors compressed using mechanical vapor recompression to strip off a weak ethanol overheads; (b) a second distillation rectifying column having a higher operating temperature than the stripping column; (c) a dehydration means in fluid communication with the rectifying column; (d) reboiler for the stripping column which partially condenses the vapor from the mechanical vapor recompression, (e) a trim condenser which completes the condensing of the vapor/liquid mix of the reboiler, (f) a heat recovery circuit which condenses the rectifying column overheads and molecular sieve dry ethanol condenser and (g) a heat exchange to transfer the recovered heat of (f) to the first distillation stripping column reboiler feed.

Claim (Index 7):
The method of  claim 5  wherein the series of distillation stripping columns comprises one distillation column divided into sections, each section in series flow for the weak feed stream from top to bottom and in parallel flow for vapor flow into the bottom and out of the top of each section.
