Encouraging numbers for corn oil feedstock
The chief technology officer for Greenshift Corp., David Winsness, said only about 4 MMgy of post-ferm corn oil was being extracted from whole stillage at U.S. ethanol plants in May 2007. Two years later, however, that number grew to 33 MMgy. By May 2010 as much as 44 MMgy of post-ferm corn oil was removed and sold as biodiesel feedstock or for other uses. Winsness said by 2022, it is expected that up to 680 MMgy of post-ferm corn oil will be siphoned from the back-end of U.S. ethanol plants.

". . . $830 million of new money . . . "
Winsness said the earlier Greenshift extraction modules were able to secure up to 0.9 pounds per bushel (lbs/bushel) of corn oil, but by applying the company’s latest advanced method, up to 1.7 lbs/bushel of post-ferm corn oil can be extracted. He said ethanol producers can make up to 7.9 cents per gallon of ethanol produced off of selling their post-ferm corn oil. “This could mean $830 million of new money to this industry,” Winsness said.


"It’s barbaric . . . "
"While most corn fractionation processes involve front-end component separation after which the nonstarch streams can be sold into various higher-value markets, Greenshift has trademarked the term Backend Fractionation to represent the selective and efficient removal of valuable components within the whole stillage. “It’s barbaric to use a hammer and chisel approach to separating corn components,” said Winsness of some front-end frac processes.

SkunK note: 

Did you notice the theme of "Innovation, not Imitation" repeated throughout the GERS presentation?   Also note that the ICM presenter spends all his time trying to say how they are "different" from their competitor - GreenShift.   It is important? That they use a "different" centrifuge and somehow are they trying to imply that they are outside the patent?

The FLOTTWEG TRICANTER  is a DECANTER CENTRIFUGE.  (go to ICMINC.com/Go to "Inventory Elimination Blowout"/Drag down "centrifuges" for description of Flottweg Tricanter) For those who think this somehow saves ICM from patent litigation just go to the first GERS patent HERE.  Got to "Edit", then go to "find on this page".  Insert "decanter" and you will see that it is listed 8 times in the patent. 

Words such as those below seem to be there to specifically STOP ICM or anyone else from using a simple substitution of one device for another to run around the patent.  I suggest those who think using a horizontal centrifugal decanter is a good defense need to read the APPROVED GERS patent.

"The descriptions are not intended to be exhaustive or to limit the disclosed invention to the precise form disclosed. Modifications or variations are also possible in light of the above teachings. For example, the syrup recovered from the centrifuge may be evaporated and processed again in a further effort to recover oil before drying. Moreover, in addition to a self-cleaning bowl type of disk stack centrifuge, a nozzle bowl disk stack centrifuge would work as a means for recovering oil from the concentrate, as would a horizontal centrifugal decanter (which may be especially beneficial when the moisture content of the concentrate is less than 50% by weight) or other like devices for separating oil from a substance including suspended solids.
************************

While GERS has continued to license their patented COES to at least three Ethanol Plants (and 5? COES) since the litigation began last fall - ICM has failed to announce one addtional corn oil extraction customer during the same time period. 

It appears the Ethanol Industry is voting with what counts - their checkbooks!SkunK bottom line is GERS would be using a DECANTER CENTRIFUGE if it worked the best.  It would still be covered by the Greenshift Patents.  ICM has used the DECANTER CENTRIFUGE and has had all sorts of reliability problems that users have wrote about in their public filings.  SEE HERE
