4. Distillers (DDG’s) Corn Oil Recovery Process
Grind corn
Cook corn
Fermentation
Separate solids (centrifuge), liquids, alcohol (distillation)
Concentrate liquids (syrup) 30 to 35% solids through evaporators
Centrifuge corn oil from concentrated liquids

5. Distillers Corn Oil Specifications

6. Distillers Corn Oil Production
80% to 85% of ethanol plants extracting
2.0 to 2.2 billion lbs of annual distillers corn oil production
Yields improving
Anti emulsion process aids
Higher process temperatures
Management focus
Fine grind
Enzymes

7. Distillers Corn Oil next steps
Increase yields to 1.0 lb/bu approximately 5.0 billion lbs / year
Potential 1.8 to 2.0 lbs of corn oil / bu
Higher protein values relative to energy value in feed
Continued challenges with changes in processing characteristics
Partial refining / bleaching at ethanol plants

8. Rail Car Situation
Petroleum companies bidding $1200 to $1500 per month = 1/2 this time last year
Petroleum companies taking delivery of new builds – returning short term leased cars
Increased safety concerns / costs
Increased traffic flows
Crude producers like flexibility to markets that rail cars provide vs pipeline
LNG competing to replace diesel

9. Renewable Documentation
Contracts specifying additional feedstock source documentation
RINS
CARB / CI index
ISCC certification
RED certification
Auditing

10. Mineral Oil Specifications
European driven – being adopted elsewhere
Likely added to existing specifications
Not able to detect food grade mineral oil vs non food grade mineral oil
Sources
Rail car / metal wipes
Pumps / hydraulics
