Industry ObjectiveTo Safely Produce & Deliver
• A liquid energy product• Quality needed• Volumes needed• Where needed• When needed• Optimum flexibility• Cost efficiently

Geography• Most Ethanol produced in Midwest
• Most petroleum refined in the Gulf Coast
• Both away from major markets
• Current refined products pipelines -wrong location or flow direction

Volume Affects Mode
• Petroleum Transportation– Wooden barrels– Rail cars of barrels– ….– Rail Tank cars– Pipelines
• Ethanol Transportation– Tank trucks– Rail cars– Barges– Unit Trains– Pipelines

Pipeline Type• Multiproduct Pipeline
– Geographic issues– Compatibility of materials, existing products– Capacity for ethanol
• Dedicated Pipeline– New or existing pipe – From and To? – Materials (nonmetallic)– Sizing of pipeline & infrastructure
• Combination– Dedicated feeders to multiproduct trunk

Stress Corrosion Cracking
• Dissolved oxygen – May act as light switch
• Saturated with oxygen – some SCC• Deaerated – No SCC
– Extreme lab conditions• Can dissolved oxygen be controlled
below the critical level?

Materials Compatibility
• Ask a terminal engineer• Many terminals currently work with high
and low ethanol concentrations
• Midwest terminals have years of excellent experience

Flexibility to Blend
• The US will go beyond E10• Terminals need the flexibility to blend
beyond E10– E85– Enhanced blends (E10 to E20)?
• Must allow best economics for local markets

Ethanol in PipelinesThere are
No Technical Barriersto moving ethanol in pipelines.
(But we do need more researchto address the operating conditions)
