• Potential found through evaluation of three key variables
Corn/Milo •Oil Content•Defines Oil Available•Sets Expectations
Decanting of Stillage
•First Partition•Centrate or Wet Cake•Potential for Oil Loss
Extraction of DCO
•Second Partition•Recovery Rate of Oil•Determines Efficiency

Strong Methodsand Data Evaluation
10
• We built our own proprietary analytical method and platform for analysis.
• Developed analytical eye for optimization throughout the plant to extract corn oil and co-products.
OUR APPROACHAnalysis
specific to ethanol
OUR ANALYTICAL METHODS
Low Standard Deviation
Stronger Mass Balance
RESULT
A more accurate mass balance for your plant.
Industry Report Card
11
A closer look - corn oil production is impacted by:• Corn flour content
(How much oil is available to extract?)
• Decanter operation (How much oil partitions to the centrate?)
• Corn oil extraction (What is the efficiency of extraction at the centrifuge?)
