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 5):
The method of  claim 1  wherein the first distillation stripping column is comprised of a series of distillation stripping columns, wherein the first distillation stripping column reboiler is comprised of a series of distillation stripping column reboilers, and a first distillation stripping column in the series receiving the feed stream of weak volatile components, each of the other distillation stripping columns in the series in succession receiving the bottom stream from the prior distillation stripping column in the series, and each distillation stripping column in the series having a reboiler of the series of reboilers which partially condenses compressed overhead vapor from the series of distillation stripping columns, the reboilers each partially vaporizing the weak volatile stream from the final distillation stripping column in the series as well as sequentially reducing the weak volatile components of the feed stream.
