Ethanol and Biofuels
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.
Eaton offers Caustic Clean-In-Place filtration solutions to the ethanol industry. By installing a mechanically cleaned filter on a recirculation loop connected to the caustic make down tank, the filter removes the particulate from the caustic tank, reducing consumption of caustic ensuring a consistent CIP cleaning process every time.
