Ethanol and Biofuels

When the fermentation part of the process is complete, these tanks are pumped out to the distillation system to separate the ethanol from the stillage, or by-product.

Because ethanol plants typically have many fermentation tanks the process is essentially continuous. The systems are optimized so that one tank is offline for cleaning every 1 - 4 hours. This allows the other tanks to be cleaned at some point along in the fermentation process. This clean up is extremely important as it must take place in a very short time period -- typically less than one hour. It also must be done very efficiently to ensure a clean tank prior to refilling. If this is not done in the proper manner, costs escalate and product quality/safety are compromised.
