RECYCLING AND REUSE OF CARBON DIOXIDE FOR TEMPERATURE CONTROL OF A FERMENTATION PROCESS

摘要

Methods and apparatus for improving the fermentation process by controlling the temperature of the fermentation tanks. Waste byproduct carbon dioxide from the fermentation process is recycled as liquid carbon dioxide and used as a coolant medium for the fermentation process. These methods and apparatus are particularly useful for maintaining temperatures of the fermentation process when applied to production of green ethanol from sugarcane.
