`
`HISTORY
`? Westfalia Separator
`- Late 2007 installation, early 2008 planned startup
`- Second installation for oil recovery
`- Built Westfalia P&lD: No oil recovered!
`- Spin test: No "free" oil
`- Westfalia: "You must have changed your process."
`? BEST Energies
`- Need to disrupt the oil-in-water emulsion
`- Time and Temperature approach
`- Batch operations during reenginering

`
`INITIAL SOLUTION
`
`?
`
`? Heat syrup from 140 °F to 190-192 °F
`- Lower temperature decreases oil yield
`- Higher temperature darkens DDGS
`Increase residence time to 20 hours
`- Lower residence time decreases oil yield
`- Higher residence time is infeasible without $
`? Result: 0.25 lb Oil / bu Corn

`
`Research Goals
`
`1) How does CVEC increase Corn Oil yield and
`maintain DDGS quality?
`2) What consistent Corn Oil yield can we obtain
`and what are the DDGS ramifications?
`3) Can we return our "Standby" stillage tank
`back to "Standby" service?

`
`1.
`
`Increasing Oil Yield
`
`? CVEC discovered literature suggesting that flavor
`compounds in an oil-in-water emulsion were
`more easily separated by the addition of a high
`HLB surfactant
`? The surfactant works to reduce interfacial tension
`between the oil and water phases, allowing oil
`droplets to agglomerate into clusters
`? CVEC is limited to food grade & Kosher additives
`? TWEEN 80 / POLYSORBATE 80

`
`2. Consistent Maximum Oil Yield
`
`? Result: 0.50 lb Oil / bu Corn
`? Need to minimize downtime
`? Need to explore other ways of maximizing
`yield
`- finer grind?
`- Heating stillage?
`? Problem: CVEC is a production organization
`with minimal research capacity

`
`3. "Standby" Stillage Tank
`
`? CVEC has lost some operation flexibility due to
`the use of an additional tank.
`Is there a low capital way of reducing the
`residence time requirement?
