Ethanol and filtration

Ethanol is a hot topic these days even in the mass media. Ronningen-Petter brand by Eaton Corporation is one of my sponsors and this is an interview with Habib Diallo who is the Project Manager in the Ethanol line of products.

"I see three Ethanol Market Challenges," Says Habib Diallo, Senior Analyst

  1. Unsustainable level of capital spending to build new plants for an energy source that is still inferior to gasoline.

  2. Measuring medium to long term effect of irrigation, pesticides and fertilizers on the nation's water supplies, and..."

I listen to the Podcast and start to get the point. What is the influence of filtering on the Ethanol production process?

  • New plants have been constructed, ethanol is becoming popular
  • Fertilizers effect on the waters through corn manufacturing has to be considered
  • We've to control the process and the effluents better
  • Productivity improvements can be achieved with the right methods
  • Long term staying power improvements
  • The challenge is to using the resources better
  • Make better decisions about how to squeeze out more from existing plants
  • Overall efficiency of operations
  • Improving the operational costs of their plants
  • Decreasing the amount of materials used
  • Running longer without stoppage
  • Leads to higher yield
  • Eliminating unnecessary downtime
  • Increasing the efficiency of capital equipment
  • All process units are linked together
  • Any downtime that isn't planned has an impact on the yield
  • Improve the yield of the plant
  • Safety of the plant
  • Not exposed to unnecessary risks
  • To get the long term staying power
  • How many ethanol installations are going in
  • In US 100 ethanol plants
  • 30 to 40 under construction now
  • Filtering

As part of the ethanol production process, water, enzymes and corn are cooked and then combined in large fermentation tanks. 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.
