- Butanol Fermentation Demonstration Plant
Our team provided front-end engineering services for a fermentation and extraction project located at a dry-grind corn to ethanol plant in Kansas. The project consisted of two sub-projects.
The first project developed the scope, schedule and estimate for adding a demonstration plant consisting of butanol fermentation and extraction process at the existing ethanol plant.
The second was to develop scope and budget for a grass roots butanol fermentation and extraction plant at full scale. Working with the technology provider, our team identified key process variables that greatly impacted equipment cost and provided the greatest risk to project success.

Some organisms naturally produce butanol. The technology provider on this project used one such organism to develop an effective conversion of butanol from starch-based sugars. Since butanol contains more BTUs per volume than ethanol and is a precursor to other chemicals, this technology is a good addition to a traditional dry grind ethanol plant. It allows more flexibility in the fuel markets and introduces the plant to the chemical market.
Our team worked closely with the technology provider to determine the best available equipment required to meet the client’s design needs for fermenting starch-derived sugars into butanol using their propriety organism. As strict sanitation requirements are not the standard in the ethanol industry, a key design consideration is the need for improved sanitary conditions required for equipment exposed to bio-organisms. In addition, efficient methods for sanitizing the equipment between batches is a must.
