• 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?)
