dc.description.abstractThe fuel ethanol industry has put into practice several techniques for minimizing energy requirements for ethanol manufacture. Thermal energy usage in fermentation grain ethanol plants has been reduced from the prior practice of 80,900 Btu per gallon ethanol to current demonstrated practice of 49,700 Btu per gallon. Future, state-of-the-art improvements are expected to reduce usage further to 37,000 Btu per gallon or less. The total energy input is projected at 52,000 Btu per gallon after adding in the electrical power. Energy savings have been achieved primarily by flash vapor reuse, pressure cascading of distillation units, and use of more efficient byproduct drying methods. These energy saving techniques should also be useful in other commercial processing applications.en
