| 摘要 |
The present invention conserves water by reducing the heat load placed on a cooling tower during the ethanol fuel production process. An air cooler is placed between the ethanol vapor condenser and the cooling tower thereby minimizing process temperature spikes before water enters the cooling tower. This, in turn, shortens the process cycle thereby increasing ethanol production. During certain climactic conditions, the cooling tower may be completely bypassed, thereby conserving more water and increasing ethanol production.
